# Email notifications

In **Settings > SMTP** tab you can setup a connection to an SMTP server.

This enables your Defguard instance to send **email notifications** to users and admins.

After you fill in all the relevant fields you can use the **Send test email** form at the bottom to test if your configuration is correct.
