General Readability and Accessibility

Writing clear, readable emails with focus on readers with visual impairments, dyslexia etc.

Please help edit this page if you have knowledge/guidance on any of these issues.


Using non-serif fonts such as the one here in this document makes text easier to read.

Extinction Rebellion do have official fonts of FUCXED and Crimson, but these aren't necessary for use on an email. Crimson is a 'serif' font - having embelishments on each letter and is therefore less readable for people with dyslexia.

Avoid using italics, capitals, or colour for emphasis. Instead, use bold text.

Font size should be at least 14 point or equivalent.


Include alternative (alt) text to describe images, tables, and graphics for people using screen readers. Just click the image after you've imported it into an email and write a description for the 'alt/title' e.g. Rebel holding pink banner reading 'Act Now' - this is good practice for accessibility reasons but could also help with deliverability

Adding images can sometimes stretch out your email width-ways and make your text appear really small (especially on a phone). You can fix these problems with the advice below...

Using 'Visual/html' method


Alt text: A grey switch with the options of 'Drag and drop' and 'Visual/HTML'. The switch is on 'Visual/HTML' and this option is circled in red for emphasis.

To set the alt tag and the size of an image, click on the image within your email and edit these options... email_image_options.png

Using 'Drag & Drop' method


Then make sure you use an image container box and put your image in there. Don't copy/paste images into text boxes. Again there are options for alt text and layout available.
