Follow up Autoresponder PRO has built-in TinyMCE editor. It is very easy to use and customizable editor. They have a very active forum going on, so support wouldn't be a problem.
We can add tables, images and different fonts etc to html emails very easy with TinyMCE editor. But the problem is the URL of the images will be stripped-out when the subscriber actually receives the email. This was the complaint from the users of Follow up Autoresponder PRO.
So I digged deep into their documentation on TinyMCE's web site and changed the code which is used to implement the TinyMCE into the autoresponder script.
PROBLEM WAS BROKEN IMAGES IN THE HTML EMAILS:
Even when users of the script add the image urls as full absolute paths during message creating, the TinyMCE truncates the first half of the url, so the images won't display in html emails when the subscribers receive it.

HOW TO FIX IT:
You need to tweak the integration code of TinyMCE a little
bit. My first code looks like this in the template files of Follow up Autoresponder PRO.

Later I added an extra line to stop the url truncation by TinyMCE. I added the following code to the present integration code:
convert_urls : false
Now the code looks like this: This code tells TinyMCE to stop converting urls to reletive url paths.
