Is there a way to customize email template further to display additional data from table?
My particular case is to include user name into the registration confirmation email (while identity is set to email). Is there any special syntax to refer to the corresponding table column in the email template? Maybe there is a way to write a kind of custom script to include into the email processing pipeline?
At the moment custom placeholders for email templates are not supported (though it may be done in future).
If you need to send a custom email you can use Event handlers for specific events (like user registration, login). I.e. all the logic for sending email is now on your side.
Although it won’t work in case of email confirmations letters with a confirmation link (since this link is created on our backend).
