Keep bounce and complaint rates healthy

The thresholds that matter and how to stay under them.

Inbox providers watch how often your email bounces or is reported as spam. Sendonia tracks the same levels Amazon SES uses to review senders.

  • Bounce rate: aim below 2%. Above 5% is critical.
  • Complaint rate: aim below 0.08%. Above 0.1% is critical.

How to stay healthy

  • Only email people who opted in.
  • Remove old, unengaged addresses before you import.
  • Use a sender name and subject line your audience recognises.
