Accessible campaigns: contrast, captions, email, social and documents
Make every campaign asset usable by more people: check text and graphic contrast against WCAG 2.2, never rely on colour alone, keep important text out of images, caption and review video, avoid flashing content, and publish emails, social posts and documents that work with assistive technology.
