### Handle Bounces, Complaints, and Unsubscribes

Delivery events protect future sends by keeping risky addresses out of normal campaigns.

Bounces, complaints, and unsubscribes are not just bad news. They are signals that help protect the list. Mailrith uses subscriber status and email delivery service events so future sends do not keep mailing people who should not receive them.

This works best when email delivery service webhooks are configured. Without webhooks, Mailrith may not receive important delivery events quickly or at all.

- Treat hard bounces as addresses that should not receive normal future sends.
- Treat spam complaints as serious negative feedback.
- Do not manually resubscribe people unless you have a clear, legitimate reason and they asked for it.
- Check webhook setup if bounces or complaints appear in your email delivery service dashboard but not in Mailrith.
- Use subscriber activity history and [Suppression Lists and Subscriber Status](https://mailrith.com/guides/suppression-lists.md) to understand what happened to a specific person.

## Fix Common Issues
### Check Complaints and Bad Addresses

A reputation or blacklist result suggests bounces, complaints, or bad list sources may be contributing to the issue.

1. Open the latest campaign results in Mailrith.
2. Review bounces, complaints, unsubscribes, and low engagement together.
3. Compare the risky campaign with the list source used for that send.
4. Keep bounced and complained subscribers suppressed.
5. Fix imports, signup forms, or subscriber targeting before sending again.
