Domain Tracking

Mailgun offers tracking for clicks, unsubscribes, and opens, with optional HTTPS protocol support on tracking URLs. To enable HTTPS, Mailgun uses Let’s Encrypt with HTTP-01 challenges through your existing tracking CNAME record to issue a TLS certificate. This setup also includes support for HTTP Strict Transport Security (HSTS) for enhanced security.

Operations

DKIM Security

Automatic Sender Security DKIM Key APIs. To enable this feature please see 'Update a domain' API docs.

Operations

Account Webhooks

Webhooks API to manage account-specific webhooks. You can create, retrieve, update, and delete webhooks programmatically. Account-level webhooks are configured independently for US and EU regions. When triggered, webhook URLs are deduplicated by event type, across account and domain levels to prevent redundant webhook sends.

Bounces

Bounces - Bounce list stores events of delivery failures due to permanent recipient mailbox errors such as non-existent mailbox. Soft bounces (for example, mailbox is full) and other failures (for example, ESP rejects an email because it thinks it is spam) are not added to the list.

Operations

Allowlist

The allowlist API provides the ability to allowlist specific addresses from being added to bounce list. You can allowlist by domain name (i.e example.com) or by specific address (i.e. alice@example.com). Mailgun doesn’t add an address to bounce list if the address is allowlisted. This API is very useful if you test against your private services and don’t want to constantly clean up bounce lists
