Here are some example of content from emails to demonstrate what is acceptable use of text over images.

In this example, the smaller text in the black box is rejected because it is not big enough to read on smaller screens. Text embedded in images is not dynamic and so will simply shrink down when viewed on smaller screens. The text that remains is acceptable because it's:

• big enough to read on smaller screens
• is permitted as illustrative text and is not essential informative text

In this example, the smaller text under the logo is rejected because it contains informative text under it which should be displayed as a caption, heading or body copy. Additionally, it is rejected because it is not big enough to read on smaller screens. The text that remains is acceptable because it's:

• big enough to read the text on smaller screens
• it is a logo
