About SendLint

SendLint checks every email against your approved assets: copy deck, links, alt text and creative. Approvals mint certificates anyone can verify.

SendLint provides 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, including the copy deck, links matrix or spreadsheet, and approved design, along with accessibility, compliance, and brand rules in any language. An AI Agent detects issues outside the rules and suggests fixes for your approval. Each round is re-checked, and sign-off issues a certificate linked to the exact HTML, helping you catch what your checklist missed.
