When you have images in your emails, be sure to use descriptive “alt tags.”
An alt tag is a word or phrase attached to an image that shows up on your recipient’s screen in case the image can’t be read by his or her email technology.

Tagging the image as “small left-hand photo” or “big blue box” won’t be of any use to the reader.
But a tag that reads “Click to here to order at [URL]” will. Be descriptive and use direct response copy.
