You can either create your messages in plain text or HTML format.
You do not need to know HTML to create HTML messages, as
we offer an HTML editor, which will let you easily change the
shape and color of your message using the tools available
in the toolbar on top of the editor.
If you know HTML, you can enter your own code into the message.
Just choose the HTML Body as your message format and click on
the link >> Enter your own HTML Code.
