Mailgun - Atako

Let your agents send emails from your Mailgun domains, add mailing list members, and read delivery events, metrics, suppressions and templates.

Connection

Authentication: API key (Private API key).
Required settings:
- Region — api for a US account (api.mailgun.net), api.eu for a domain hosted in the EU (api.eu.mailgun.net).

Mailgun dashboard → Account Settings → API keys → Create key: name it and copy the private API key secret (shown only once). A domain sending key is not enough — the agent also reads domains, events and lists. Set the region to “api.eu” if your domains are hosted in the EU region.See Mailgun’s documentation.
