Layout and accessibility Required
Send text instead of pictures of text
Put every important word in live text. Never send a message that is one large image.
How to do it
Live text can be read when images are blocked, searched, translated, resized and read aloud. Image-only messages also look like spam to filters. Keep text in images to logos and decoration, and repeat any offer in live text.
How to check
Turn images off. The subject, the main message and the call to action are all still readable.
