-  It's a nice perk that Mautic can use any transport provided by Symfony Mailer. However, be aware that such transports (from Symfony) don't support batch sending, even via API.

They also don't support transport callback handling used for bounce management.

These plugins are available in the :doc:`Mautic Marketplace </marketplace/marketplace.rst>`.
