Shaan,
I have accomplished this by creating a single text attribute on an entity and then, in a microflow, create an html string with the table containing all of your content. You can loop through the items you want in your email and create a row for each one. Once you’ve got it built, put that html string into the text attribute and you can use it in your email.
Hope that helps,
Mike
