The ``gmail`` transport is simply a shortcut that uses the ``smtp`` transport

and sets ``encryption``, ``auth_mode`` and ``host`` to work with Gmail.

..note::

Depending on your Gmail account settings, you may get authentication errors

within your app. If your Gmail account uses 2-Step-Verification, you should

`generate an App password`_ to use for your ``mailer_password`` parameter.

You should also ensure that you `allow less secure apps to access your Gmail account`_.
