Editing of Email body (HTML Template) having dynamic binding

I have created an Email template having dynamic bindings which get populated before the user sends out the email via Wappler Mailer API.
How to Allow users to edit the HTML Email Template so that the user may make necessary edits before sending the mail.

Hi.
The current implementation of email and HTML templates is limited to what you have.

You can allow users to create templates and save in DB, and with custom module then use that DB value as email body instead of template file.
