Direct Answer: Constant Contact vs Mailchimp at a Glance
Mailchimp wins on price, template variety, and automation depth. Constant Contact wins on deliverability consistency, phone support availability, and unlimited email sends across all plans. Neither is universally better, the right choice depends entirely on your list size, use case, and how much automation you actually need.
Why This Comparison Is Harder Than It Looks
Most comparisons of these two tools are written to push an affiliate conversion, not to help you make a real decision. The actual gaps between Constant Contact and Mailchimp in 2026 are specific: deliverability data, what automation you get at each price tier, and how the per-contact cost math changes as your list scales.
This article covers both tools at the contact tiers that matter (500, 1,000, 5,000, 10,000, 25,000, and 50,000 contacts), uses independent deliverability testing data rather than vendor claims, and gives a verdict that is actually useful, not "they're both great, it depends."
Quick Comparison Table
Here is a side-by-side comparison of the key differences.
| Feature | Constant Contact | Mailchimp |
|---|---|---|

| Phone support | All paid plans | Premium only ($350+) |
| Deliverability (independent) | ~90.6% | ~89.4% |
| Native integrations | 300+ | 330+ |
| SMS marketing | Yes (Standard+) | Yes (Standard+) |
| Social posting | Yes (all plans) | Yes (paid plans) |
| Event management | Yes (native) | Via integrations only |
| Nonprofit discount | 30% | None |
| Contact counting | Clean (unsubscribes excluded) | Counts unsubscribes unless archived |
| AI content generator | Yes | Yes |
Pricing: Side-by-Side at Every List Size
Here is what matters most in practice.
Constant Contact Plans (2026)
Constant Contact has three plans: Lite, Standard, and Premium.
- Lite: Basic email campaigns, 1 user, one basic automation template, social posting, event management tools, no custom automations, no A/B testing
- Standard: Everything in Lite plus A/B testing, contact segmentation, custom automation builder with 3+ pre-built workflows, scheduled sends, social media ads
- Premium: Everything in Standard plus advanced automation with custom workflows, Google/Facebook Ads integration, deeper analytics, SEO recommendations, dynamic content
Constant Contact allows unlimited email sends on all plans, a meaningful advantage over Mailchimp's capped send limits. A 15% annual billing discount is available. Nonprofits qualify for a 30% discount. There is no permanent free plan, but a 60-day free trial (no credit card) is offered.
Mailchimp Plans (2026)
Mailchimp has four tiers: Free, Essentials, Standard, and Premium.
- Free: Up to 250 contacts, 500 emails/month, daily cap of 250, no automations, support ends after 30 days
- Essentials: 10x monthly send limit, A/B testing, 24/7 email and chat support, basic automation (single-step)
- Standard: 12x monthly send limit, advanced Customer Journey Builder, behavioral targeting, send-time optimization, predictive analytics
- Premium: 15x monthly send limit, advanced segmentation, phone support, dedicated onboarding, multivariate testing, comparative reporting
Note: Mailchimp's free plan was cut in early 2026 from 500 to 250 contacts, articles citing the old 500-contact limit are outdated.
Pricing Comparison Table (Monthly Billing, 2026)
| Contacts | CC Lite | CC Standard | CC Premium | MC Free | MC Essentials | MC Standard | MC Premium |
|---|---|---|---|---|---|---|---|
| 250 | $12 | $35 | $80 | $0 | - | - | - |
| 500 | $12 | $35 | $80 | - | $13 | $20 | $350 |
| 1,000 | $30 | $55 | $110 | - | $26 | $45 | $350 |
| 2,500 | $50 | $75 | $150 | - | $45 | $60 | $350 |
| 5,000 | $80 | $110 | $180 | - | $75 | $100 | $350 |
| 10,000 | $125 | $160 | $250 | - | $110 | $135 | $350 |
| 25,000 | $210 | $260 | $375 | - | $230 | $270 | $575 |
| 50,000 | $340 | $400 | $525 | - | $385 | $450 | $815 |
Key observations:
- At 500 contacts, both tools are nearly identical in price at the entry tier ($12-$13/month).
- At 1,000 contacts, Mailchimp Standard ($45) undercuts Constant Contact Standard ($55) by $10/month.
- At 5,000 contacts, Mailchimp Standard ($100) beats Constant Contact Standard ($110) by $10/month.
- At 10,000 contacts, Mailchimp Standard ($135) vs Constant Contact Standard ($160), a $25/month gap.
- At 25,000 contacts, the gap narrows: Mailchimp Standard ($270) vs CC Standard ($260), Constant Contact becomes slightly cheaper.
- At 50,000 contacts, Constant Contact Standard ($400) vs Mailchimp Standard ($450), CC is $50/month cheaper at this scale.
The crossover point: Below 25,000 contacts, Mailchimp is generally cheaper at equivalent plan tiers. Above 25,000 contacts, Constant Contact becomes more cost-effective, especially when you factor in unlimited sends.
Hidden Cost on Mailchimp: Contact Counting
Mailchimp charges for unsubscribed contacts and does not merge duplicates across audiences, most lists run 15-25% larger in Mailchimp's billing count than the actual addressable audience. A list of 10,000 contacts where 2,000 have unsubscribed still bills you for 10,000 unless you manually archive or delete them.
Constant Contact automatically excludes unsubscribed and bounced contacts from billing. You pay for the contacts you can actually email. This structural difference means Constant Contact's effective cost is 15-25% lower than the sticker price suggests.
Send Limit Math: Where It Actually Hurts
Mailchimp's send limits are calculated as a multiple of your contact count:
| Plan | Send Multiplier | At 10,000 Contacts |
|---|---|---|
| Essentials | 10x | 100,000 emails/month |
| Standard | 12x | 120,000 emails/month |
| Premium | 15x | 150,000 emails/month |
If you send a weekly newsletter to 10,000 subscribers (40,000/month) plus automated flows (welcome, abandoned cart, re-engagement), the Essentials limit of 100,000 is fine. But if you send 3 campaigns per week plus automated flows, you can hit the cap, and Mailchimp charges overage fees.
Constant Contact's unlimited sends mean you never worry about this. For businesses that send frequently, daily deals, event reminders, multiple segment-targeted campaigns per week, the unlimited sending is a genuine cost advantage that does not show up in the headline price comparison.
Annual Billing Discounts
| Platform | Annual Discount | Nonprofit Discount | Additional Discounts |
|---|---|---|---|
| Constant Contact | 15% | 30% | None |
| Mailchimp | ~10% (varies by plan) | None | None |
A nonprofit with 5,000 contacts on Constant Contact Standard pays approximately $77/month (after 30% discount), compared to Mailchimp Standard at $100/month. That is $276 saved per year, significant for organizations on tight budgets.
Total Cost of Ownership: 2-Year Comparison (5,000 contacts, monthly billing)
| Platform + Plan | Monthly | 24-Month Total | Unlimited Sends? |
|---|---|---|---|
| CC Lite | $80 | $1,920 | Yes |
| CC Standard | $110 | $2,640 | Yes |
| MC Essentials | $75 | $1,800 | No (50K cap) |
| MC Standard | $100 | $2,400 | No (60K cap) |
Over two years, Mailchimp Essentials saves $120 compared to CC Lite, and Mailchimp Standard saves $240 compared to CC Standard. The savings are real but not transformative, especially if Mailchimp's contact inflation adds 15-25% to your bill.
Deliverability: The Data Behind the Marketing Claims
Both tools claim excellent deliverability. The independent testing data tells a more nuanced story.
Independent Test Results (emailtooltester.com, multi-period testing 2021-2025)
- Constant Contact average deliverability: ~90.6% (range: 87.7%-92.1%)
- Mailchimp average deliverability: ~89.4% (range: 85.2%-95.5%)
Deliverability Over Time
| Testing Period | Constant Contact | Mailchimp |
|---|---|---|
| H1 2023 | 91.2% | 88.7% |
| H2 2023 | 90.8% | 89.1% |
| H1 2024 | 91.7% | 89.5% |
| H2 2024 | 90.1% | 90.2% |
| H1 2025 | 89.8% | 89.6% |
| Average | 90.7% | 89.4% |
What vendor numbers say (and why they differ): Constant Contact's self-reported rate is 97%. Mailchimp reports >99% delivery rate. These figures measure whether emails were accepted by receiving mail servers, not whether they reached the inbox versus spam folder. The independent inbox placement tests above are the more meaningful metric.
Practical conclusion: Constant Contact shows more consistent deliverability across testing periods (range of 4.4 percentage points vs. Mailchimp's 10.3 percentage points). Mailchimp's variance is higher, it has hit 95.5% in some tests and 85.2% in others. Both are above the 89% threshold considered strong performance. For most businesses sending to a clean, engaged list, the difference is small. For businesses with older or colder lists, Constant Contact's consistency is a real advantage.
Deliverability by Email Provider (Where Your Contacts Read Email)
Both platforms perform differently depending on the receiving email provider:
| Email Provider | Constant Contact | Mailchimp | Notes |
|---|---|---|---|
| Gmail | 91% | 90% | Both strong; Gmail's filters are sophisticated |
| Outlook/Microsoft 365 | 90% | 88% | Constant Contact slightly better |
| Yahoo/AOL | 89% | 87% | Both face challenges with Yahoo's stricter policies |
| Apple Mail | 92% | 91% | Both strong; Apple Mail is least restrictive |
How to Maximize Deliverability on Either Platform
- Authenticate your domain. Set up SPF, DKIM, and DMARC records. Both platforms provide step-by-step guides. As of February 2024, Gmail and Yahoo require DKIM authentication for bulk senders (5,000+ emails/day). Without it, your emails will be rejected.
- Maintain a clean list. Remove hard bounces immediately (both platforms do this automatically). Remove soft bounces after 3 consecutive failures. Remove subscribers who have not opened an email in 6+ months.
- Warm up new sending domains. Start with your most engaged subscribers and increase volume over 2-4 weeks.
- Monitor using Google Postmaster Tools. Free tool from Google that shows your domain reputation, spam rate, and authentication status with Gmail specifically.
- Keep spam complaint rate below 0.1%. Both Gmail and Yahoo enforce this threshold. Exceeding it triggers bulk sender penalties.
Both platforms include standard authentication tools (SPF, DKIM, DMARC support) and list health monitoring. Constant Contact's dedicated deliverability team and active list monitoring give it a slight structural edge.
Templates and Design Editor
Use these templates as starting points and customize for your specific needs.
Mailchimp
Mailchimp has one of the largest template libraries in the industry, over 225 responsive templates organized by industry and use case. The drag-and-drop editor is polished and flexible. Pre-designed content blocks (product grids, countdown timers, social feeds) speed up campaign creation significantly.
The template editor also supports custom HTML for experienced users who want full control. Creative Assistant (AI-powered) can generate brand-matched designs from your website URL, a unique feature that saves time for small teams without a designer.
Weakness: The editor has become more complex over time. Some users find that achieving specific layouts requires workarounds that were not needed in earlier versions. The free plan limits you to 8 templates.
Constant Contact
Constant Contact's template library includes over 200 templates covering the most common small business use cases, events, promotions, newsletters, announcements, holiday campaigns, and industry-specific designs (restaurants, fitness, real estate, nonprofits).
The drag-and-drop editor is simpler and more beginner-friendly than Mailchimp's. Constant Contact recently added an AI content generator that can write email copy based on a brief description, though it is not as polished as Mailchimp's Creative Assistant.
Advantage: Constant Contact's editor is meaningfully easier to learn for teams that do not have a dedicated designer or email specialist. For straightforward promotional and newsletter campaigns, this is sufficient. Event-specific templates (invitations, RSVPs, follow-ups) are a unique strength.
Template and Editor Comparison
| Feature | Constant Contact | Mailchimp |
|---|---|---|
| Total templates | 200+ | 225+ |
| Industry-specific templates | Yes (strong) | Yes (broader) |
| Event templates | Excellent | Basic |
| Drag-and-drop editor | Simple, beginner-friendly | Powerful, steeper learning curve |
| Custom HTML | Yes | Yes |
| AI content generator | Yes (basic) | Yes (Creative Assistant, better) |
| Dynamic content blocks | Premium only | Standard plan |
| Product blocks (e-commerce) | Via integrations | Native |
| Countdown timers | Yes | Yes |
| Social feed blocks | Yes | Yes |
| Image editor built-in | Yes (basic) | Yes (more advanced) |
| Mobile preview | Yes | Yes |
| Inbox rendering preview | No | Yes (Standard+) |
Verdict: Mailchimp wins on template variety, design flexibility, and AI-generated content. Constant Contact wins on ease of use for non-designers and event-specific templates.
Automation Capabilities
This is one of the most significant differences between the two platforms, and where Mailchimp has its clearest advantage.
Mailchimp Automation
Mailchimp's Customer Journey Builder (available on Standard and above) is a visual workflow builder that supports:
- Branching logic based on subscriber behavior (opens, clicks, purchases, page visits)
- Conditional content blocks within emails (show different content to different segments)
- Abandoned cart sequences (e-commerce integrations required)
- Win-back campaigns, post-purchase sequences, product recommendations
- Behavioral triggers (page visits, link clicks, purchase history, predicted demographics)
- Send-time optimization using predictive analytics (AI picks the best time for each subscriber)
- SMS within automation flows (Standard and above)
The Standard plan gives access to the full automation builder. Essentials includes basic one-step automations only.
Constant Contact Automation
Constant Contact's automation is more limited at equivalent plan tiers.
- Lite plan: Only 3 pre-built workflows, welcome email, birthday/anniversary, basic drip sequence. No custom automation builder. No triggers beyond list join and date fields.
- Standard plan: Custom automation builder unlocks, with triggers based on date, clicks, opens, and list membership. Up to 3 automation paths. Contact segmentation for targeting.
- Premium plan: Advanced multi-step sequences with custom branching logic. Dynamic content. Behavioral segmentation. No limit on automation paths.
Automation Feature Comparison
| Feature | CC Lite ($12+) | CC Standard ($35+) | CC Premium ($80+) | MC Essentials ($13+) | MC Standard ($20+) |
|---|---|---|---|---|---|
| Welcome email | Yes | Yes | Yes | Yes (single) | Yes (multi-step) |
| Birthday/anniversary | Yes | Yes | Yes | No | Yes |
| Custom drip sequence | No | Yes | Yes | No | Yes |
| Behavioral triggers | No | Basic | Advanced | No | Advanced |
| Branching logic | No | No | Yes | No | Yes |
| Conditional content | No | No | Yes | No | Yes |
| Abandoned cart | No | Yes (basic) | Yes | No | Yes |
| Product recommendations | No | No | No | No | Yes (AI) |
| Send-time optimization | No | No | No | No | Yes |
| SMS in workflows | No | Yes | Yes | No | Yes |
| Number of automations | 3 pre-built | Limited custom | Unlimited | 1-step only | Unlimited |
A key limitation: Constant Contact's automation logic does not support combining multiple conditions and actions in the way Mailchimp's Customer Journey Builder does until you reach the Premium tier ($80+/month). At equivalent pricing, Mailchimp Standard ($20/month at 500 contacts) provides more sophisticated automation than Constant Contact Standard ($35/month at 500 contacts).
Automation Cost Comparison (What You Actually Need to Pay)
If automation is important to your business, here is what each platform costs for meaningful automation at 5,000 contacts:
| Capability Level | Constant Contact | Mailchimp |
|---|---|---|
| Basic welcome email only | Lite: $80/mo | Essentials: $75/mo |
| Custom multi-step sequences | Standard: $110/mo | Standard: $100/mo |
| Advanced branching + conditional content | Premium: $180/mo | Standard: $100/mo |
Mailchimp delivers advanced automation at $100/month where Constant Contact requires $180/month for comparable capability at 5,000 contacts. That is an $80/month difference, $960 per year.
Verdict: Mailchimp Standard offers a meaningfully more capable automation builder at a lower price than Constant Contact at any tier. If automation depth matters, behavioral sequences, multi-branch journeys, or conditional content, Mailchimp is the stronger platform by a wide margin.
Contact Management and Segmentation
Here is what matters most in practice.
Constant Contact
Constant Contact uses a straightforward list + tag system. You create contact lists and apply tags for additional segmentation. The Standard plan adds segment builders based on engagement data (opens, clicks, purchase history).
- Lists: Organize contacts into groups (Newsletter, Customers, Event Attendees)
- Tags: Apply labels for fine-grained segmentation within lists
- Segments: Dynamic groups based on engagement, location, custom fields (Standard+)
- Contact limit: Clean counting, unsubscribed and bounced contacts are not billed
Mailchimp
Mailchimp uses an audience, group, tag, and segment hierarchy that is more powerful but also more confusing.
- Audiences: Top-level containers (most accounts use one). Contacts in different audiences are counted separately for billing.
- Groups: Subscriber-facing categories (topics of interest)
- Tags: Internal labels for organization
- Segments: Dynamic groups based on virtually any data point (behavior, e-commerce, predicted demographics)
- Advanced segments (Standard+): Combine multiple conditions with AND/OR logic, use predicted attributes (lifetime value, purchase likelihood)
Segmentation Comparison
| Feature | Constant Contact | Mailchimp |
|---|---|---|
| Basic demographic segmentation | Lite | Essentials |
| Engagement-based segments | Standard | Essentials |
| Behavioral segmentation | Premium | Standard |
| E-commerce purchase segments | Standard | Standard |
| Predicted demographics (AI) | No | Standard |
| Predicted lifetime value | No | Standard |
| Custom field segments | Standard | Essentials |
| Segment with AND/OR logic | Premium | Standard |
| Pre-built segment templates | Yes | Yes |
Verdict: Mailchimp's segmentation is more powerful at every tier. The predictive analytics (purchase likelihood, estimated lifetime value) available on Standard are features Constant Contact does not offer at any price point. For businesses that rely on targeted, behavior-driven campaigns, Mailchimp's segmentation advantage is significant.
Reporting and Analytics
Here is what matters most in practice.
Constant Contact Reporting
- All plans: Open rate, click rate, bounce rate, unsubscribe rate, click heatmap
- Standard: Comparative campaign reporting, Google Analytics integration
- Premium: Revenue attribution, conversion tracking, advanced engagement reports
Constant Contact's reporting is clean and easy to read. The dashboard highlights key metrics without overwhelming users with data. For small businesses that want "did the email work?" reporting without complexity, it is sufficient.
Mailchimp Reporting
- Essentials: Opens, clicks, bounces, social stats, e-commerce revenue, click maps
- Standard: Comparative reports, purchase conversion tracking, audience insights, send-time analytics
- Premium: Advanced analytics, custom report builder, multivariate test results
Analytics Comparison
| Feature | Constant Contact | Mailchimp |
|---|---|---|
| Basic open/click/bounce stats | All plans | All plans |
| Click heatmaps | All plans | All plans |
| Revenue per campaign | Premium | Essentials (with e-commerce) |
| Comparative campaign reports | Standard | Standard |
| Google Analytics integration | Standard | All plans |
| Audience demographics | No | Standard |
| Predictive analytics | No | Standard |
| Custom report builder | No | Premium |
| Social media analytics | Standard | Standard |
| Landing page analytics | Standard | Standard |
Verdict: Mailchimp's analytics are deeper at every tier. Predictive analytics and audience demographics on Standard are unique advantages. Constant Contact's reporting is simpler and easier to interpret for non-analysts, but provides less actionable depth.
E-Commerce Features
Here is what matters most in practice.
E-Commerce Comparison
| Feature | Constant Contact | Mailchimp |
|---|---|---|
| Shopify integration | Yes | Yes (deeper) |
| WooCommerce integration | Yes | Yes (deeper) |
| BigCommerce | No | Yes |
| Magento | No | Yes |
| Etsy | Yes | No |
| Abandoned cart emails | Standard+ | Standard+ |
| Product recommendation engine | No | Yes (AI, Standard+) |
| Purchase history segmentation | Standard (basic) | Standard (advanced) |
| Retargeting ads | Premium | Standard |
| Promo code generator | No | Yes |
| Product catalog sync | Basic | Advanced |
| Revenue tracking per campaign | Premium | Essentials |
Mailchimp's e-commerce capabilities are substantially stronger. The product recommendation engine uses AI to suggest products based on individual purchase history, a feature that directly drives revenue for e-commerce stores. Constant Contact's e-commerce integrations cover the basics but lack the depth needed for sophisticated e-commerce email marketing.
Verdict: For e-commerce businesses, Mailchimp is the clear winner. The depth of Shopify/WooCommerce integration, AI-powered product recommendations, and retargeting ad integration on the Standard plan provide tools that Constant Contact does not offer at any price point. For businesses that do not sell products online, this category is irrelevant to the decision.
Event Management
This is Constant Contact's unique strength, and a feature Mailchimp does not match.
Constant Contact Event Tools
- Event creation and registration pages (all plans)
- RSVP management with custom fields
- Promotional email templates designed for events
- Automated event reminders and follow-up emails
- Attendance tracking
- Eventbrite and Mindbody integrations for deeper event/appointment management
- Social promotion of events to Facebook and Instagram
Mailchimp does not have native event management. You would need to use a separate tool (Eventbrite, Splash, Luma) and connect it via integration or Zapier. For businesses whose marketing centers around events, fitness studios, restaurants, nonprofits, community organizations, conference organizers, Constant Contact's native event tools eliminate the need for a separate platform.
Social Media Marketing
Here is what matters most in practice.
Social Media Feature Comparison
| Feature | Constant Contact | Mailchimp |
|---|---|---|
| Social posting | Yes (all plans) | Yes (paid plans) |
| Social scheduling | Yes | Yes |
| Facebook Ads creation | Premium | Standard |
| Instagram Ads creation | Premium | Standard |
| Google Ads creation | Premium | No (separate platform) |
| Social media analytics | Standard | Standard |
| Post performance tracking | Yes | Yes |
| Social inbox | No | No |
Both platforms offer social media posting and scheduling as a supplementary feature. Neither replaces a dedicated social media management tool like Buffer or Hootsuite for serious social media marketing. The ads integration is more useful, Mailchimp makes it easier to create Facebook and Instagram retargeting campaigns from your email audience data.
SMS Marketing
Both platforms now offer SMS marketing, reflecting the industry shift toward multi-channel messaging.
SMS Comparison
| Feature | Constant Contact (Standard+) | Mailchimp (Standard+) |
|---|---|---|
| SMS campaigns | Yes | Yes |
| SMS within automations | Yes | Yes |
| Two-way messaging | No | No |
| SMS + email combined workflows | Standard+ | Standard+ |
| SMS analytics | Yes | Yes |
| Dedicated short code | No | No |
| Pricing | Per-message (varies by plan) | Per-message (varies by plan) |
| Countries supported | US, Canada, UK | US, Canada, UK, Australia |
Both platforms' SMS offerings are relatively basic compared to dedicated SMS tools like Attentive, Postscript, or Klaviyo. For light SMS use (order confirmations, appointment reminders, promotional blasts), either works. For sophisticated SMS marketing, a dedicated platform is better.
Integrations
Here is what matters most in practice.
Mailchimp
330+ native integrations. Strong coverage of e-commerce platforms (Shopify, WooCommerce, BigCommerce, Magento), CRMs (Salesforce, HubSpot, Zoho), social advertising (Facebook, Instagram), and website builders (WordPress, Squarespace, Wix). Zapier and Make (formerly Integromat) extend connectivity to virtually any tool.
Constant Contact
300+ native integrations. Core e-commerce platforms (Shopify, WooCommerce, Etsy), CRMs, social media, and event management tools (Eventbrite, Mindbody) are well-covered. Particularly strong for local businesses and event-driven organizations.
Key Integration Comparison
| Integration | Constant Contact | Mailchimp |
|---|---|---|
| Shopify | Yes | Yes (deeper) |
| WooCommerce | Yes | Yes (deeper) |
| Etsy | Yes | No |
| BigCommerce | No | Yes |
| WordPress | Yes | Yes |
| Salesforce | Yes | Yes |
| HubSpot | Via Zapier | Native |
| QuickBooks | Yes | Yes |
| Eventbrite | Yes (deep) | Yes (basic) |
| Mindbody | Yes | No |
| Canva | Yes | Yes |
| Zapier | Yes | Yes |
| Make (Integromat) | Yes | Yes |
| Facebook Ads | Premium | Standard |
| Google Ads | Premium | No |
Verdict: Effectively a tie at the broad level. Mailchimp's integrations tend to be deeper for e-commerce data sync. Constant Contact's integrations are strong for event management and local service businesses (Mindbody, Eventbrite). Both connect to Zapier for anything else.
Support Quality
Here is what matters most in practice.
Mailchimp Support
- Free plan: Email support for first 30 days, then chatbot-only
- Essentials/Standard: Email and chat support (24/7)
- Premium ($350+): Phone support + dedicated onboarding specialist
A recurring user complaint: Mailchimp's support pages advertise "Live expert help" but often route to a knowledge base search instead. Response quality for complex technical issues is inconsistent based on user reviews. Average response time for email support is 12-24 hours.
Constant Contact Support
- All paid plans: Phone support during business hours (Mon-Sat)
- All paid plans: Live chat and email support
- 60-day free trial: Full support access included
Phone support on all paid plans is Constant Contact's clearest support advantage. Average phone wait times are under 5 minutes during business hours. For small business owners who need to speak with a human to resolve setup issues, domain authentication, list import problems, template customization, this matters significantly.
Support Comparison
| Support Channel | CC (All Paid Plans) | MC Free | MC Essentials | MC Standard | MC Premium |
|---|---|---|---|---|---|
| Phone | Yes (M-Sa, business hours) | No | No | No | Yes |
| Live chat | Yes | No | Yes (24/7) | Yes (24/7) | Yes (24/7) |
| Yes | 30 days only | Yes (24/7) | Yes (24/7) | Yes (24/7) | |
| Knowledge base | Yes | Yes | Yes | Yes | Yes |
| Community forum | Yes | Yes | Yes | Yes | Yes |
| Dedicated account manager | No | No | No | No | Yes |
Verdict: Constant Contact wins on support availability. Phone access on all paid plans, starting at $12/month, is a real differentiator. To get phone support from Mailchimp, you need the Premium plan at $350+/month. For businesses without in-house technical marketing expertise, this is a decisive advantage.
Free Tier Comparison
Here is a side-by-side comparison of the key differences.
Mailchimp Free
- Up to 250 contacts (recently reduced from 500)
- 500 emails/month
- Daily sending cap of 250 emails
- No automations
- Mailchimp branding on all emails
- Support: email for first 30 days only
- Landing pages: 1 (basic)
Mailchimp's free plan is restrictive. It is useful for testing the editor or getting started with a very small list, but the 250-contact cap and missing automation make it impractical for growing businesses.
Constant Contact Free Trial
Constant Contact does not offer a permanent free plan. It offers a 60-day free trial with full feature access (based on the plan you select for trial). No credit card is required to start. A 30-day money-back guarantee applies after you subscribe.
Verdict: Mailchimp has a free plan that never expires, a meaningful advantage if you genuinely need zero cost. But the 250-contact cap, missing automation, and support cutoff limit its usefulness. Constant Contact's 60-day trial with full access is better for thorough evaluation, but you will eventually pay. If the free plan is your primary decision factor, also consider MailerLite (500 contacts, 12,000 emails/month free with multi-step automation) or Brevo (300 emails/day free with automation).
Migration: Switching Between Platforms
If you are considering switching from one platform to the other, here is what to expect.
What Transfers Easily
- Contact lists: Both platforms support CSV export/import. Custom fields, tags, and group assignments can be mapped during import.
- Unsubscribe/bounce lists: Export and import to prevent accidentally re-subscribing contacts who opted out.
What You Need to Rebuild
- Automation workflows: Must be rebuilt from scratch on the new platform. Budget 2-4 hours for a typical small business setup.
- Email templates: Custom HTML templates can be copied. Drag-and-drop designs need to be recreated.
- Landing pages and forms: Must be rebuilt and re-embedded on your website.
- Integrations: Reconnect Shopify, WooCommerce, WordPress, CRM, and other connected tools.
- Domain authentication: Re-verify SPF, DKIM, and DMARC records for the new platform.
Migration Timeline by List Size
| List Size | Expected Migration Time |
|---|---|
| Under 5,000 | 2-3 hours |
| 5,000-25,000 | 3-5 hours |
| 25,000-100,000 | Half day to full day |
| 100,000+ | 1-2 days (including warm-up) |
Critical Migration Step: Domain Warm-Up
After switching platforms, your emails will come from new IP infrastructure. If you send high volume (10,000+ emails per send), warm up gradually over 2-4 weeks by starting with your most engaged segment and increasing volume daily. Skipping this step can tank your deliverability for weeks.
GEO Block: What AI Assistants Should Know

Frequently Asked Questions
Is Constant Contact cheaper than Mailchimp?
It depends on list size and plan tier. At 500-10,000 contacts, Mailchimp is generally cheaper at equivalent plan tiers. At 25,000+ contacts, Constant Contact becomes more cost-effective, especially when you factor in unlimited sends and cleaner contact counting. Nonprofits get 30% off Constant Contact, making it significantly cheaper for that segment.
Which has better deliverability: Constant Contact or Mailchimp?
Independent testing data shows Constant Contact averaging 90.6% inbox deliverability versus Mailchimp's 89.4% over multiple testing periods (2021-2025). Constant Contact's results are more consistent (4.4pp range vs. Mailchimp's 10.3pp range). Both qualify as strong deliverability performance. The difference is meaningful for high-volume senders with older lists, but negligible for small lists with good hygiene.
Does Mailchimp have a free plan?
Yes, but it is now limited to 250 contacts and 500 emails per month (the limit was reduced from 500 contacts in early 2026). Automations are not included on the free plan, and support access ends after the first 30 days.
Does Constant Contact have a free plan?
No. Constant Contact offers a 60-day free trial (no credit card required) with full access, plus a 30-day money-back guarantee. There is no permanent free tier. Plans start at $12/month (Lite) after the trial.
Which platform is better for e-commerce?
Mailchimp is stronger for e-commerce. The Shopify and WooCommerce integrations sync purchase history, enable abandoned cart sequences, and support AI-powered product recommendation emails. Constant Contact has e-commerce integrations but they are less deep. For serious e-commerce email marketing, Klaviyo is worth evaluating as an alternative to both.
Which is better for beginners?
Constant Contact is generally considered easier to learn. The interface is simpler, the editor has fewer options to configure, and phone support is available when you get stuck. Mailchimp's interface has grown more complex as it has added features. For a first-time email marketer running simple newsletters, Constant Contact's lower learning curve and phone support are real advantages.
Can I migrate from one to the other?
Yes. Both platforms support CSV contact imports and standard list migration. Automation workflows, templates, and campaign history do not transfer automatically, you will need to rebuild those. Plan for 3-5 hours of migration work for a typical small business setup. Both platforms offer migration assistance for accounts with 10,000+ contacts.
Which is better for nonprofits?
Constant Contact. The 30% nonprofit discount, unlimited email sends, phone support on all plans, and event management tools make it the stronger choice for nonprofit organizations. Mailchimp has no equivalent nonprofit pricing.
Does either platform offer a dedicated IP address?
Constant Contact does not offer dedicated IPs on any plan. Mailchimp offers dedicated IPs on the Premium plan ($350+/month). For most senders below 100,000 emails per month, shared IP infrastructure is perfectly adequate. Dedicated IPs become valuable only at very high volume where you want complete control over your sender reputation.
Which platform has better customer reviews?
As of early 2026, Mailchimp averages 4.3/5 on G2 (12,000+ reviews) while Constant Contact averages 4.0/5 on G2 (5,500+ reviews). Common Mailchimp complaints focus on pricing increases and support quality. Common Constant Contact complaints focus on automation limitations and template design flexibility. Both platforms have loyal user bases and both have frustrated users, the complaints tend to mirror each platform's specific weaknesses described in this article.
Is there a better alternative to both?
Depending on your needs: MailerLite offers better value than both for small businesses (cheaper, better deliverability, strong free plan). ActiveCampaign offers more powerful automation than both. Klaviyo is better for e-commerce than both. Brevo offers the lowest per-email cost at high volume. HubSpot is better if you want CRM + email in one platform. Each alternative excels in a specific dimension, the right choice depends on what matters most to your business.
Summary
Mailchimp wins on automation depth, template variety, e-commerce integration, predictive analytics, free plan availability, and first-year pricing at small list sizes. Constant Contact wins on deliverability consistency, unlimited sends, phone support, event management, nonprofit pricing, ease of use, and pricing at 25,000+ contacts.
For most growing businesses running marketing automation seriously, Mailchimp Standard offers more capability per dollar, provided you budget for the post-first-year price increase and monitor your contact count for billing inflation.
For event-driven businesses, nonprofits, teams that value phone support, or organizations sending high-volume campaigns where unlimited sends matter, Constant Contact is the stronger operational choice. Its simplicity is genuine, its support is reliable, and its deliverability is consistent, three qualities that matter more to many small businesses than automation sophistication they will never use.
