how to insert the html email

[stariknatali]

Sorry I'm new to the Forum, besides kosnozychie.
I have mail on roundcube , but do not know how to insert the html email. Where to paste the code? An absolute must tell button maker

When composing email you should see an option to use plain text or html. If not, it could be disabled in the configuration. Check the defaults.inc.php and config.inc.php files.
