Formatting, readability and accessibility

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

Text and Style guide

Use sans serif fonts (such as Arial and Calibri). Once you have chosen a font it's best to stick to it; don't mix fonts in an e-mail.

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

Font size should be at least 14 point or equivalent.

Use simple language that is clear and easy to understand. Use shorter sentences and avoid using abbreviations and jargon.

Some more general guidance on text, style, colour and layout.


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.
