Marketing is where a small business meets AI first, and where it burns money fastest. A new tool launches every week, each with a free tier that looks generous right up to the moment you hit the wall. This is a buying guide rather than a launch roundup: how to decide which AI marketing tools deserve a line in your budget, and which are simply another subscription you will cancel in three months.
Name the job before you name the tool
"AI marketing tool" is not one category. At least four different jobs hide under that label:
- Writing: blog posts, email copy, ad copy, captions.
- Email and automation: campaigns, welcome sequences, send-time optimisation.
- Social scheduling: captions, queueing posts, reporting.
- Visual content: social graphics, brand kits, image generation.
Most small teams buy for the job they enjoy and then discover the bottleneck was a different one. Track for one week where the hours actually go. If the honest answer is "we write everything at the last minute", buy writing help. If the answer is "posts never go out", buy scheduling. The tool follows the bottleneck, never the other way around.
Map the free tiers before you pay anything
Every tool worth considering ships a free tier that is real but deliberately capped. The paywall sits exactly where the tool becomes convenient: removing branding, raising AI limits, or unlocking automation. That is not a trick. It means a free stack genuinely works until you outgrow one specific limit, and you should find that limit on purpose rather than by surprise.
The caps worth knowing:
- HubSpot: the free CRM tier is permanent and includes Breeze Copilot, the chat-style assistant. The advanced Breeze agents sit in the Professional tier.
- Mailchimp: free covers 250 contacts and 500 emails per month. Contact-priced plans count unsubscribed and non-engaged contacts as well, unless you archive them.
- Buffer: free covers 3 channels with up to 10 queued posts each, and the AI Assistant is included on every plan, including the free one.
- Canva: free includes a monthly allowance of AI uses that resets every month, which is workable for light use.
- Jasper: no permanent free plan, only a 7-day trial. That alone tells you who it is built for.
Three stacks by budget
Stack A, nothing per month. HubSpot free CRM for contacts and Breeze Copilot, Buffer free for scheduling, Canva free for graphics. This covers a solo founder who posts a few times a week and writes their own copy. It stops working the day you need automation or a branded asset.
Stack B, around $20 per month. HubSpot Starter at about $20 per seat, Mailchimp Essentials from $13 per month for 500 contacts and 5,000 sends, or Canva Pro at $18 per month, which drops to about $12 per month if you pay $144 per year. Pick one, not all three.
Stack C, a two-to-five person content team. Jasper Pro at $59 per month billed annually, or $69 month to month, for one seat. At this price the question is not whether the tool is good but whether your team produces enough on-brand content to justify it. A solo founder gets most of the same drafting done by pairing a general AI assistant with the free Canva tier.
What each tool is actually good at
HubSpot Breeze is the all-in-one: contacts, email, forms, landing pages, and an AI layer on top. Best when you want one place to live.
Mailchimp is still the default for email. Its AI features, from content generation to subject-line help and send-time optimisation, are part of the paid plans, and the value shows up in automation more than in raw writing.
Buffer is the budget scheduler that respects small budgets. It prices per channel instead of per seat, which matters the moment a second person needs access.
Canva Magic Studio is where non-designers already work. Magic Write, Magic Design, the background remover and image generation are bundled into every plan.
Jasper is the premium copywriting platform: brand voice, templates for every format from blog posts to ad copy, and a canvas editor. It earns its price when consistency across a team matters more than the cost of one seat.
The two traps
The free tier can shrink. Mailchimp cut its free plan to 250 contacts and 500 emails per month, roughly half of what it offered before. A stack you built on a free tier is a stack you may have to rebuild.
Contact pricing punishes a stale list. On plans priced by contact count, unsubscribed and non-engaged contacts keep costing money until you archive them. Cleaning the list is not housekeeping, it is a price cut.
A four-week rollout
- Name the bottleneck and pick the job.
- Run the free stack for that job only, and note the day you hit a cap.
- Add one paid tier that removes exactly that cap.
- Review the bill after a month and cancel whatever did not earn its line.
Prices move often. The figures above were checked in September 2026 — confirm them on the vendor's own pricing page before you commit.
