* ``loose`` uses a simple regular expression (just checks that at least one ``@``
character is present, etc.). This validation is too simple and it's recommended
to use one of the other modes instead;
* ``html5`` uses the same regular expression as the `HTML5 email input element`_,
making the backend validation consistent with the one provided by browsers;
* ``html5`` uses the regular expression of the `HTML5 email input element`_,
except it enforces a tld to be present.
* ``html5-allow-no-tld`` uses exactly the same regular expression as the `HTML5 email input element`_,
making the backend validation consistent with the one provided by browsers.
* ``strict`` validates the address according to `RFC 5322`_ using the
`egulias/email-validator`_ library (which is already installed when using
:doc:`Symfony Mailer </mailer>`; otherwise, you must install it separately).

.. versionadded:: 6.2

The ``html5-allow-no-tld`` mode was introduced in 6.2.

.. tip::

The possible values of this option are also defined as PHP constants of
:class:`Symfony\\Component\\Validator\\Constraints\\Email`
(e.g. ``Email::VALIDATION_MODE_STRICT``).


The default value used by this option is set in the
:ref:`framework.validation.email_validation_mode <reference-validation-email_validation_mode>`
configuration option.
