The Importance of a One-Sheet Attachment Promo in an Email

Q:

What is the importance of a “one-sheet” attachment promo in an email sent to a potential client? How many images and should this promo include any descriptive text about the images, background/bio, pitch, etc., or should all of the text be in the body of the email?

A:

When saying hello in an email, it can be good to have a fast visual sampling looking like it belongs in that email. The key to a one-sheet promo is that it’s a quick relatable read of a small number of images only, not needing that extra step of being clicked to open.
