mySMTP webhooks will notify your application in real time when something happens to an email you sent, such as a delivery, bounce, or spam complaint. Webhooks are planned for release in late Q4 2026, together with the Email API.
Webhooks are not available yet. Event types, payload formats, and setup steps will be published here at launch.

​
What webhooks are for

Typical uses for email webhooks include:
  • Removing hard-bounced addresses from your lists automatically.
  • Suppressing recipients who mark your mail as spam.
  • Updating delivery status in your CRM or application.
  • Alerting your team when bounce or complaint rates rise.
