The built-in Email Action sends messages as emails. This Action will by default send out a styled email with the most important aspects of an alarm, including a link back into Humio with the result.

Should you want to modify the email, you can do so by checking _Use custom email template and filling out the Message Body Template. On cloud we will add a small disclaimer on top of every email to clarify that it is sent as a Humio Action. On prem customers have the option to enable it themselves, by setting the ALERT_DISCLAIMER environment variable. Custom Email templates are only available for self-hosted and licensed cloud customers. See Message Templates documentation page for how to use our templates.

Example configuration for the Alert disclaimer:

ALERT_DISCLAIMER=This is an Alert from ${repoName} repository.

The ${repoName} will be replaced by the name of the view or repository.
