Rich text email with item lists

I would like to create a rich-text email which contains a list of items, e.g. from a custom relationship table.  Is this possible, as I see no way of adding a repeating structure in the mail template editor?  For example, how could I list all of a person's AD accounts, including SamAccountName, Mail, OU and domain for each.

Alternatively, can I use a report to create a rich-text email or would this have to be as a PDF file attachment?

I'm using Q1IM 6.0.1.
