What the warning means

  • Your bounce or complaint rate crossed Mailchimp's threshold.
  • If it stays high, Mailchimp can pause or suspend sending to protect their servers.
  • The fix is removing the contacts causing the bounces and complaints — not sending less.

Mailchimp's term for this: Omnivore warning

This isn't a you problem. Every list rots.

Natural decay

People change jobs and abandon inboxes — addresses die quietly.

Bot signups

Bots submit real people's addresses through your forms; those people mark you as spam.

Old imports

Contacts from past tools or purchased lists that were never verified.

Proof

We got a bounce warning the week before our biggest send of the year. The free analysis showed us how much of our list was bad and gave us a sample we could check ourselves — that was enough to trust it. We paid for the deep clean, and the campaign shipped on schedule. No panic, no guesswork.
