Auto-Clean Bounced & Invalid Emails
Automatically remove invalid emails and hard bounces
Syncs hard bounces and invalid emails from Mailchimp daily, automatically removing them from lists to improve deliverability and keep compliance records clean.
Email list hygiene directly impacts sender reputation and deliverability rates. Every email service marks bounces, but cleaning lists is manual. This automation runs daily, pulling all hard bounces and invalid emails from Mailchimp, then automatically removing them from active lists to prevent re-mailing dead addresses. It also logs bounce details by type (domain invalid, address invalid, mailbox full) for compliance audits. Many regulations require proof of list maintenance — this automation creates audit logs showing when addresses were removed and why. Hard bounces and stale addresses come off the list daily instead of accumulating until a send gets throttled. List hygiene stops depending on someone remembering to do it.
Runs daily at 2:00 am using Mailchimp, run by your Marketing Manager.
