Quick Answer
Log in to Mailgun and go to Sending → Domain Settings. Select the correct domain, locate Unsubscribe, click Edit, toggle the setting on or off, and click Save.
What the Unsubscribe Setting Controls
Mailgun’s Unsubscribe setting controls unsubscribe behavior at the sending-domain level. If you manage multiple domains, you can configure this setting independently for each one.
Selecting the correct domain before making changes is important because updating one domain does not automatically update the others in your Mailgun account.
Navigation path: Mailgun → Sending → Domain Settings → select a domain → Unsubscribe.
