SendLint

SendLint is email QA for agencies and in-house email teams. It checks every line, link, alt tag and module of the built email against your approved assets (copy deck, links matrix and design) plus accessibility, compliance and brand rules, in any language. An AI Agent catches what no rule covers and writes the fix for you to approve. Every round is re-checked, and sign-off issues a certificate tied to the exact HTML. Find what your checklist missed.
