SendLint checks an email against your approved deck before anyone sends it
Grounded in available product and source data
SendLint is an autonomous QA agent for email. It reads your copy deck and your approved creative, then checks copy, links, images, accessibility, metadata, spam, rendering and brand guidelines in a single pass.
A finding quotes the deck line beside the email line and names the fix, so a second round only re-checks what moved. When a round is clean, the tool issues a certificate bound to the final HTML, and reopening the round revokes it.
