Every email has a goal and 99 out of a hundred times that involves the subscriber taking an action. So the call to action is one of the most important parts of any email. But what if you can’t find them?
Even if you swear the piece is strictly informative, you must have an action in mind for the reader to take. (Share? Comment?) If not, why send it in the first place?
So be sure to think this through and make it clear and easy.
