To enable incoming email alerts with Mailgun in Keep, you don’t need to configure anything on your Mailgun account—Keep uses its own Mailgun setup and handles routing internally. In Keep, add the Mailgun provider and configure its authentication fields: the email address to receive alerts (auto-populated), an optional sender filter, and (optionally) extraction rules for parsing email content with regex. You’ll also need to set the MAILGUN_API_KEY environment variable for authentication, and you can select the Mailgun region (US/EU) via the UI or the MAILGUN_REGION env var—defaults to US if not set.

To validate, send a test email to the address shown in the provider’s authentication section and check that the alert appears in Keep. By default, the alert’s name comes from the email subject, the source from the sender, and the message from the stripped text content. You can use extraction rules to pull structured data from the email, for example, extracting severity from the subject with (?P<severity>\w+): as a regex pattern on the subject field.

If you see errors about missing subject or message, make sure your emails include both a subject and a plain text body—these are required for alert creation. For more details and examples, see the Mailgun provider documentation and Mailgun provider code.
