Bounce and complaint protection

Automatic guards that pause sending before real damage is done.

Updated Sep 10, 2026 1 min read

MunchReach watches bounce and complaint rates per mailbox and pauses a mailbox that crosses a safety threshold.

Why

A mailbox with a climbing bounce or complaint rate is destroying reputation with every additional send. Pausing costs you a day; not pausing costs you the domain.

What to do when it triggers

  1. Open Warmup or Email Accounts and read the pause reason.
  2. Fix the underlying cause: clean the list, remove the source of bad addresses, repair authentication.
  3. Resume only afterwards.

Important notes

Resuming without fixing anything trips the same guard again and compounds the damage. Treat a protection pause as information, not an obstacle.
