Questions

Common questions, straight answers.

What do I enter to connect Mailgun?

Your Mailgun API key, the sending domain you configured at Mailgun, and the region — US or EU. PostFrame stores the key in its secrets vault.

Is the EU region supported?

Yes. Pick EU when you connect and PostFrame sends through Mailgun's EU endpoint for that connection.

What happens when this provider returns an error?

The send moves to your next provider by priority on the same request, up to three attempts. After five failures inside five minutes the provider's circuit opens and it is skipped for sixty seconds before being tried again.

Where do I see how Mailgun is performing?

The Providers report in PostFrame analytics breaks delivery, bounce and complaint numbers down by connected provider, so Mailgun sits next to SES or Postmark on one screen.
