ActiveCampaign is a widely used marketing automation platform with powerful email sequencing, CRM, and segmentation capabilities. Its deliverability, however, depends entirely on the quality of the contact data feeding those automations.
ActiveCampaign bounce cleanup is the process of identifying, suppressing, and removing bounced and high-risk contacts from your ActiveCampaign account before they accumulate into a domain reputation problem. This guide covers how ActiveCampaign handles bounces, where to find them, how to clean them, and how to prevent future accumulation.
How ActiveCampaign Handles Email Bounces
ActiveCampaign automatically processes bounce events and applies status flags to affected contacts:
Hard bounces: Permanent delivery failures (invalid address, non-existent domain, account permanently closed). ActiveCampaign automatically marks these contacts as 'Bounced' and removes them from future email sends. This suppression is automatic but must be maintained actively.
Soft bounces: Temporary delivery failures (full mailbox, server temporarily unavailable). ActiveCampaign tracks soft bounces and will convert repeated soft bounces to a hard bounce status after a threshold of failures on the same address.
Unsubscribes: Contacts who click unsubscribe are marked as unsubscribed and excluded from future emails. This is separate from bounced contacts.
Understanding the distinction is important: ActiveCampaign's automatic bounce handling protects your account from the immediate impact on deliverability, but it does not remove the underlying data quality problem — your list still contains contacts whose email addresses were never valid to begin with.
Finding Bounced Contacts in ActiveCampaign
Contacts Segment: Bounced Filter
In ActiveCampaign, go to Contacts. Apply a filter: Status = Bounced. This shows all contacts that ActiveCampaign has automatically marked as bounced based on delivery failures.
Campaign Bounce Reports
In each Campaign report (Campaigns > select campaign > Reports), the Bounce section shows:
Hard bounce count and percentage for that campaign.
Soft bounce count and percentage.
Individual contact-level bounce details when you click into the bounce section.
List-Level Bounce Analysis
For a list-level view: Lists > select list > Statistics. This shows the cumulative bounce history for all contacts in that list, helping identify which lists have the worst bounce rates.
ActiveCampaign Bounce Cleanup: Step-by-Step
Step 1: Export Bounced Contacts
From the Contacts view with the Status = Bounced filter applied, export all bounced contacts to CSV. Retain this export for reference — you may want to cross-reference against your CRM or attempt to find alternative contact information for high-value accounts.
Step 2: Delete Bounced Contacts
In ActiveCampaign, select all bounced contacts using the bulk select option and delete them. Deleting bounced contacts removes them from your contact count (which may reduce your subscription cost if you are near a tier threshold) and eliminates any possibility of accidentally re-importing them.
Note: If you use ActiveCampaign as your CRM, consider whether any bounced contacts have associated deal or pipeline data before bulk deleting. Archive those contacts rather than deleting if they have a commercial history.
Step 3: Clean Soft-Bounced Contacts
Export contacts that have soft-bounced 3 or more times. These addresses are at high risk of becoming permanent delivery failures and should be verified before being included in future sends.
Run the soft-bounce email addresses through a bulk email verify tool. Remove those classified as invalid. Flag catch-all addresses for cautious monitoring.
Step 4: Clean Unengaged Contacts
Beyond bounced contacts, unengaged contacts are a deliverability risk in ActiveCampaign. Create a segment: Contacts who have not opened any email in the past 12 months AND have not clicked any email in the past 12 months.
Run a re-engagement campaign on this segment. Suppress non-responders. This is critical for maintaining high engagement rates in ActiveCampaign, which directly influences inbox placement.
Step 5: Verify Your Remaining Active List
After cleaning bounced and unengaged contacts, export all remaining active contacts and run a full verification pass. This identifies addresses that have not yet bounced but are classified as invalid or high-risk by SMTP verification.
Remove invalid results. Segment catch-all results for separate, monitored campaigns.
Preventing Future Bounce Accumulation in ActiveCampaign
Real-Time Verification on Forms
ActiveCampaign's native forms do not perform SMTP-level email verification. Add a verification step by:
Using ActiveCampaign's Webhook integration to trigger a verification API call on form submission before the contact is created.
Implementing a JavaScript-based verification check on the form field using the BounceProof API before form submission.
Using a middleware tool (Zapier, Make.com) to intercept form submissions, verify the email, and only create the ActiveCampaign contact if verification passes.
Import Verification Policy
Establish a mandatory policy: all CSV imports to ActiveCampaign must pass through bulk email verify processing before upload. Never import an unverified list directly.
Automated Bounce Monitoring
Set up an ActiveCampaign automation:
Trigger: Contact tag 'Bounced' is added (ActiveCampaign adds this tag automatically on hard bounce).
Action: Notify the list owner via email with the bounced contact details for CRM cleanup.
Action: Add the contact to a 'Suppression' list for reference.
This gives visibility into bounce events as they happen rather than discovering them in quarterly audits.
ActiveCampaign Deliverability and Bounce Rate Thresholds
ActiveCampaign monitors bounce rates at the account level and will issue warnings or account restrictions if bounce rates consistently exceed safe thresholds:
Hard bounce rate: Keep below 2% per campaign. ActiveCampaign's own guidance flags accounts with persistent hard bounce rates above 5%.
Spam complaint rate: Keep below 0.1%. ActiveCampaign integrates with ISP complaint feedback loops and reports complaint rates in account dashboards.
Exceeding these thresholds for multiple consecutive campaigns can trigger account-level sending restrictions. Proactive cleanup is substantially easier than recovering from a restricted account.
Key Takeaways
ActiveCampaign bounce cleanup addresses hard-bounced contacts (automatically flagged by ActiveCampaign), soft-bounced contacts (requiring manual verification), and unengaged contacts (a deliverability risk independent of bounce status).
ActiveCampaign's automatic hard bounce suppression is a protection mechanism, not a substitute for proactive list cleaning.
Prevention requires real-time verification on forms, mandatory pre-import verification policies, and automated bounce monitoring workflows.
Keep hard bounce rates below 2% per campaign to avoid ActiveCampaign account-level sending restrictions.
Frequently Asked Questions
Does ActiveCampaign automatically remove bounced contacts?
ActiveCampaign automatically suppresses hard-bounced contacts from future email sends by marking them as 'Bounced.' It does not automatically delete these contacts from your account — deletion must be done manually or through automation.
Can I re-activate a bounced contact in ActiveCampaign?
Technically yes, but it is strongly inadvisable. If an address hard-bounced, it failed permanent SMTP-level delivery validation. Re-activating it and sending again will produce another hard bounce, which counts against your deliverability metrics.
How can I quickly reduce ActiveCampaign bounce rates?
Run a bulk verification pass on all active contacts and suppress invalid addresses before the next send. This is the fastest single action that reduces bounce rates — typically reducing hard bounce rates by 60–90% on the post-verification campaign.
Will cleaning bounces improve my ActiveCampaign deliverability score?
Yes. ActiveCampaign's internal deliverability scoring is influenced by your account's bounce rate history. Sustained clean sending with low bounce rates improves your sending reputation within the platform and with the ISPs that ActiveCampaign's infrastructure sends through.
Conclusion
ActiveCampaign bounce cleanup is an essential operational discipline for any marketing team using the platform for significant email volume. The combination of deleting bounced contacts, verifying and cleaning soft-bounce addresses, suppressing unengaged contacts, and implementing real-time validation on forms produces a list that ActiveCampaign can send safely and effectively.
Start with the bounced contacts filter. The numbers will tell you how urgent the cleanup is — and they will almost always be more urgent than the last time you checked.
