Why should you add Alt-text to images?
Alt text allows visually impaired users to "see" the image through screen readers.
Alt text is displayed in some email clients (such as Outlook) when images are not enabled.
Not adding alt text to all images increases the risk of your email being flagged as spam.
How to add Alt-text
Select the image.
Below the image in the right-hand panel, you'll find a text field called “Alternative text”.
Enter your alt text there.
Alt-text (or alternative text) is a way to provide information for those who can’t see the image - whether due to visual impairment, poor internet connection, or other reasons.
It should give a brief description so that even those who can’t view the image still receive the essential message.
Alt text should be short (ideally under 50 characters).
It should focus on the function of the image, not just describe what it looks like.
Example:
If the image is a right-pointing arrow linked to the next page, the alt text should be:
“Next page” - not “Arrow pointing right”.
Images that are purely decorative or don’t convey meaningful content should still have an alt text - use a simple “-” (dash) in these cases.
Leaving alt text blank can cause issues, as many screen readers will instead read out the image’s web address.
