We all know the trick of copy/paste to add static HTML in the mail but to add dynamic content is a different kettle of fish ...
In particular, I think about the following needs:
- Display a table containing the information related to the current record (eg list of contacts from an account)
- Show a link to a form without displaying any url but just a clickable word
<a href="aLink">Click here</a>
will just display
In the same way, you can display HTML table with CRM content and insert it in mail body.
[UPDATE] Code example - Url builder. This code create an hypertext html control that will be used in email body. You can set a text for the hypertext control with the input property and you get back the hypertext control in output property
