Email¶
Control how Zammad sends and receives email.
Hint
- Using Gmail / G Suite?
Set up a Google channel instead.
- Using Microsoft 365?
Set up a Microsoft 365 IMAP or Microsoft 365 Graph channel instead.

- 🚛 Migrate existing email channel to “XOAUTH” channel
At this moment Zammad supports XOAUTH for the following providers:
Microsoft 365 IMAP Email (formerly Office 365)
Note
Microsoft 365 Graph Email supports XOAUTH as well, but currently there is no migration option. Instead, you have to remove the existing and add the new channel manually.
- 👥 Accounts
Connect Zammad to your email provider so that it can watch your inbox, send auto-replies, and more.
(Self-hosted users may have already completed this step during new system setup.)
- 🗂️ Filters
Make sure new tickets show up in the right place with automated, if-this-then-that rules for all incoming email.
- 📜 Signatures
Customize signatures for all outgoing email.
- ⚙️ Settings
Manage options like:
set the “From:” address on system notifications
raise the limit on attachment sizes
modify subject-line prefixes (e.g., use “AW:” instead of “RE:”)
Hint
Want to manually edit email subjects or always copy parent messages into your replies?
Check the ✍️ Composer Settings.
- 📇 Header based actions
Manipulate auto response behavior or incoming routing.
Warning
🤓 This is a very advanced topic.
