Handle Bounces, Complaints, and Unsubscribes
Delivery events help protect future sends by keeping risky addresses out of normal campaigns.
Overview
Bounces, complaints, and unsubscribes are not only bad news. These events help protect your list. Mailrith uses subscriber status and email delivery service events so future campaigns do not keep emailing people who should not receive them.
Delivery event handling works best when email delivery service webhooks are configured. Without webhooks, Mailrith may receive important delivery events late or not receive them at all.
What to Check
- 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 to be resubscribed.
- Check the webhook setup if bounces or complaints appear in your email delivery service dashboard but do not appear in Mailrith.
- Use subscriber activity history and Suppression Lists and Subscriber Status to understand what happened to a specific person.
Fix Common Issues
Check Complaints and Bad Addresses
A reputation or blacklist check may show that bounces, complaints, or poor list sources are contributing to the issue.
- Open the latest campaign metrics in Mailrith.
- Review bounces, complaints, unsubscribes, and low engagement together.
- Compare the risky campaign with the list source used for that send.
- Keep subscribers who bounced or complained suppressed.
- Fix imports, signup forms, or subscriber targeting before you send again.
