Settings

Go to Settings → Mailpit in the Control Panel, or create a config/mailpit.php file:

<?php

use craft\helpers\App;

return [
  'host' => App::env('MAILPIT_HOST'),
  'type' => App::env('MAILPIT_TYPE'),
];

Setting	Config key	Description
Host Address	host	The URL of the Mailpit web interface, e.g. https://mailpit.test.
Display Location	type	page shows Mailpit in the navigation (default), utility in the utilities.

Tip

Both settings support environment variables.

Note

The plugin only shows Mailpit, it doesn’t change how Craft sends emails. Set that up in Settings → Email, e.g. with the SMTP transport.

Caution

The Control Panel embeds Mailpit, so the host must be reachable from your browser. An http:// host inside an https:// Control Panel is blocked as mixed content.
