Integration

Verify your ActiveCampaign audience before you send

ActiveCampaign runs Lists, Campaigns, and Automations off the same contact record, so a bad address does not just bounce a send — it can trigger automations, skew lead scores, and sit in reporting as an active contact. Verifying a List with Bounceless before you import or re-send catches dead mailboxes and disposable addresses while they are still rows in a CSV, not contacts already wired into your account's workflows.

How it works

[01]Export your ActiveCampaign list to CSVIn ActiveCampaign, go to Contacts > Lists and open the list you want to check. Use the Status dropdown to choose Active, Unconfirmed, Unsubscribed, Bounced, or Any, click Export, then name the export and pick fields in the Export Options modal before exporting.
[02]Upload the CSV to BouncelessIn the Bounceless dashboard, create a new bulk verification job and upload the exported CSV. Every address gets a confidence level, reason codes, and a Pre-Send Decision.
[03]Download the verified resultsWhen the job finishes, download the results file. Addresses are grouped by Pre-Send Decision: send, review, or suppress.
[04]Re-import the clean list into ActiveCampaignIn ActiveCampaign, click Contacts, then Import, then Import from File, and upload the send-decision addresses. Map the columns, select the destination list under Select Lists, and check Update Existing Contacts so re-imported rows refresh existing records instead of creating duplicates.
[05]Suppress the invalid addressesImport the suppress-decision addresses in a second pass and choose Import as Excluded in the Import Options dropdown. This adds them to the account-wide Exclusion list so they stop receiving campaigns and automation emails without deleting the contact record or the list history.

Steps are sourced from ActiveCampaign's official documentation (reference) and have not yet been walked on a live ActiveCampaign account by a Bounceless team member — treat exact menu labels as indicative until this note is removed.

When to run it

Pre-send hygiene on an existing listExport a List filtered to Bounced or Unconfirmed status (or the full list with Status set to Any), verify it with Bounceless, then re-import with Update Existing Contacts checked, or route the invalid rows straight into the Exclusion list instead of deleting them.
New-list intake before the first campaignBefore a purchased or partner list ever touches ActiveCampaign, verify it with Bounceless and import only the send-decision rows as Active Contacts. That keeps a brand-new list from tripping ActiveCampaign's own sender-reputation and deliverability monitoring on the roadmap on day one.
Ongoing suppression alongside engagement cleanupBounceless checks syntax, domain, and mailbox-level validity; ActiveCampaign's own engagement-based automations handle unsubscribes for contacts who stop opening or clicking. Run both so the Exclusion list and list statuses reflect deliverability and engagement, not just one or the other.

Common questions

Does this integration require connecting the ActiveCampaign API?

No. The workflow is CSV-based: export a list from Contacts > Lists, verify it in Bounceless, then re-import the clean rows. That keeps your ActiveCampaign API URL and key out of the loop entirely, and it works the same way regardless of which ActiveCampaign plan you are on, since list export and CSV import are both built-in account features.

Should I delete invalid contacts or use the Exclusion list?

For most cleanup passes, importing invalid addresses as Excluded is the safer choice. The Exclusion list stops an address from receiving campaigns or automation emails across the whole account without touching its per-list subscription status or deleting the contact record, so you keep the history if you ever need to review it later.

Does ActiveCampaign's List Cleanup tool already do this?

Not the same job. ActiveCampaign's List Cleanup tool only exists on accounts created before February 22, 2022, and it removes contacts by list status or a manual email list, which is reactive housekeeping. Bounceless verification happens before you import or re-send, catching addresses that would bounce rather than cleaning up after they already have.
