# Sending emails

Sending emails via Mailgun is supported out of the box.

The following environment variables must be set for email sending to be enabled:

• MAILGUN_API_KEY - the Mailgun domain sending API key.
• MAILGUN_API_ENDPOINT - the Mailgun API endpoint (e.g https://api.eu.mailgun.net/).
• MAILGUN_FROM_ADDRESS - email address for the from field in an email - must end in @<DOMAIN> where <DOMAIN> is the domain for which Mailgun sending is configured.

If the mailer is enabled then the mailer property in the bootstrapped object will be set.
