Theming

The email message text goes through three transformations before sending:

1. Template File

   A template file is applied to your message header, subject, and body text. The default template is the included htmlmail.html.twig file. You may copy this file to your email theme directory (selected below), and use it to customize the contents and formatting of your messages. The comments within that file contain complete documentation on its usage.

2. Theming

   You may choose a theme that will hold your templates from Step 1 above. If the Echo module is installed, this theme will also be used to wrap your templated text in a webpage. You use any one of over 800 themes to style your messages, or create your own for even more power and flexibility.

3. Post-filtering

   You may choose a text format to be used for filtering email messages after theming. This allows you to use any combination of over 200 filter modules to make final changes to your message before sending.

   Here is a recommended configuration:

   • Emogrifier Converts stylesheets to inline style rules for consistent display on mobile devices and webmail.

   • Transliteration Converts non-ASCII text to US-ASCII equivalents. This helps prevent Microsoft "smart-quotes" from appearing as question-marks in Mozilla Thunderbird.

   • Pathologic Converts relative URLS to absolute URLS so that clickable links in your message will work as intended.
