# SendLint

> SendLint is an email QA platform that verifies marketing emails against their approved sources before they're sent: the copy deck (line by line, English and French), the approved creative (PDF/XD, block by block), every link followed through tracking wrappers to its real destination, WCAG 2.1 AA accessibility, real Chromium rendering with an Outlook risk overlay, spam and deliverability signals, and brand voice. When a campaign round passes its client's compliance policy, SendLint mints a certificate (id like SL-2026-XXXXX) that binds the approved emails to their exact bytes by SHA-256; anyone can verify the final HTML byte-for-byte on the public verify page, and a pre-send API gate can block a send whose bytes changed after approval.
