Accessibility Testing
Help more subscribers actually read your email, not just receive it.
Preflight checks colour contrast, alt text, and accessibility issues before you send so more people can read, understand, and act on your message.
Make More Emails Readable
Accessibility is revenue protection, not a nice-to-have.
We run your HTML through APCA-W3 (WCAG 3) to flag colour contrast issues in your text before you send.
Accessibility helps make sure more of your customers can see, read, and act on your email, not just receive it.
Alt Text Checks
Help every image carry its message.
Catch missing or incomplete alt text so key visuals, CTAs, and product content still make sense when images don't load or someone uses assistive technology.
Language Verification
Help assistive technology read your content.
We use a language identification model to check your content matches any declared language in the markup. This helps screen readers and other assistive technology understand your content correctly, preventing wrong language or mixed-language content slips in a campaign.
