When contact count grows faster than contact quality, ActiveCampaign gets noisier to work with.
The fix is straightforward: export the data, review it, and stop mailing the addresses that are clearly causing drag.
Step 1: export the contacts
Export the audience or segment you want to review as a CSV.
You can clean:
- the full contact base
- older or low-engagement segments
- recently imported contacts
- campaign-specific send lists
Step 2: run the CSV through MailCull
Upload the file to Verify List and review the status breakdown.
MailCull helps surface:
- malformed addresses
- typo domains
- disposable providers
- domains that are not set up to receive mail
Step 3: act on the results
For most workflows:
- remove or suppress undeliverable
- review risky
- keep deliverable
That gives you a more trustworthy audience before the next send.
Why this is worth doing
The payoff is practical:
- fewer avoidable bounces
- more confidence in send quality
- less wasted audience space
