Set up Postmark

A newly connected provider becomes the one that sends. Other connected email providers stay as fallbacks after a hard failure. Authdog's managed provider sends when none of yours is active.

Prepare the server

In Postmark, open the server you will send from and copy its Server API token. Confirm the From address is a verified sender signature, or belongs to a domain Postmark has confirmed. Authdog does not verify domain ownership for you. An unconfirmed sender still fails at send time.

Leave Message stream blank to use outbound. Set a stream only when this server sends auth mail on a dedicated stream.

Connect Postmark

In the Authdog console:

1. Select the project and environment.
2. Open Notifications > Providers.
3. Select the Email channel.
4. Choose Postmark and select Connect.
5. Enter:

6. Save. Postmark becomes the active provider.
7. Select Test, enter a recipient outside your own domain, and confirm delivery.

The server token is encrypted and is not loaded back into the browser. On a later edit, leave it blank to keep the stored token. Enter a new value only to replace it.

Use Set active if you connected Postmark but another provider is still in use. Use managed returns delivery to Authdog.

Set the visible From name and Reply-to under Notifications > Configuration. Those defaults apply to every template, independent of which provider sends.

Test it

1. Send the provider test and confirm the message arrives.
2. Trigger a real template, such as a magic link or an invitation, in the same environment.
3. Confirm the send appears under Notifications > Events.

Use a separate Postmark server and token for production. Provider configuration does not copy between environments.
