To be able to receive webhooks from Mailgun, your Home Assistant instance needs to be accessible from the web and you need to have the external URL configured.

To set it up, go to the integrations page in the configuration screen and find Mailgun. Click on configure. Follow the instructions on the screen to configure Mailgun.

You will get a URL of the following format: https://<home-assistant-domain>/api/webhook/9940e99a26fae4dcf6fe0a478124b6b58b578ea4c55c9a584beb1c9f5057bb91. To receive webhooks from Mailgun, you need to provide that URL as a callback URL in the Webhooks tab of the Mailgun Control Panel.

There is currently support for the following device types within Home Assistant:


# Example configuration.yaml entry
  domain: EXAMPLE.COM
  api_key: YOUR_API_KEY

Configuration Variables

domain string Required

This is the domain name to be used when sending out mail. Needs to be the first custom domain you have set up.

api_key string Required

This is the API token that has been generated in your Mailgun account.

sandbox boolean (Optional, default: false)

(Deprecated) Whether to use the sandboxed domain for outgoing mail. Since the domain item is required, it should be set to the sandbox domain name, so this isn’t needed.

Events coming in from Mailgun will be available as events in Home Assistant and are fired as mailgun_message_received. The data specified by Mailgun will be available as the event data. You can use this event to trigger automations.

You can then consume that information with the following automation:

    platform: event
    event_type: mailgun_message_received
      action: call_service
    service: light.turn_on


The Mailgun notification service allows you to send emails via Mailgun’s REST API. It requires the Mailgun component to be set up.
