Email QA for developers and marketing teams
Real client previews, accessibility audits, and delivery checks that help you ship error‑free emails.
I've been working with our internal AI QA agent for the past couple of weeks so my brain is in this space. Preflight is SO much better than our AI QA tool, so 👏👏👏👏

Features
Reach every subscriber with
Accessibility Checks
Accessibility isn't just about compliance.. it's about better experiences for everyone. Preflight helps you catch email issues that might impact readablity and conversion.
By using advanced perceptual contrast technology (earmarked for WCAG 3.0), you aren't just staying compliant, you're ensuring your message resonates with the widest possible audience.
