You can view which of your user's email addresses bounced, complained and the rate at which these events occurred within your OneSignal dashboard Settings > Email > Email Reputation or Suppressions.

Email Reputation

The rates in which your users bounce or report your emails as spam over a 24 hour, 7 day, and 30 day period. Rates are calculated across all email sends in the current app.

If your bounce and spam report rates are too high, it will affect your domain and IP reputation which reduces deliverability and potentially violates our Acceptable Use Policy & Code of Conduct.

See How to improve email deliverability and lower bounce rate? for more details.

Suppressions

Track which email addresses bounced and complained. These addresses will be removed from further email sends.

You can add emails manually with the Add Email button and remove emails from the list with the trash can icon.
