As with all email, the first hurdle is to write a subject line that says, “must open.” Great subject lines telegraph the content of the message and promise a product, service, or outcome of real value. So many e-mail sales messages have FREE or DISCOUNT in the subject line that those words would seem to be a prerequisite. But after the first dozen or so free offers, the reader is wary and wants something more.

Visuals help your recipients quickly understand what the point of the email is.
