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.
I've spent my career between product and quality: product management in edtech and fintech, and these days QA for email campaigns. That job means checking marketing emails against everything the client approved, word by word: the copy deck, every link, every alt tag, every module of the design, across launch and reminder versions and multiple languages, round after round. It's work where 99% right is still a fail, because the remaining 1% is a wrong offer or a missing legal line landing in a million inboxes, and there is no unsend.
SendLint is the tool I kept wishing existed, so I put my PM hat back on and built it.
What it does:
• Checks every line, link and alt tag of the built email against your approved assets: the copy deck, the links matrix or spreadsheet, in any language • Compares the email to the approved design, module by module • Runs accessibility (WCAG 2.1 AA), compliance, spam and the client's own brand rules in the same pass • An AI Agent catches what no rule covers, like an offer the legal copy doesn't back up, and writes the HTML fix for you to accept or reject • Tracks every finding round over round until the build is clean, with waivers on record • On sign-off, issues a certificate tied to the exact HTML, with a public page anyone can use to verify that what went out is what was approved
The 60-second video shows the whole flow. You can also try it on your own email, no account needed, at sendlint.com/demo.
Launch offer: 30% off your first 3 months with code PRODUCTHUNT, until November 10.
I'd love to hear how your team handles email QA today, especially if you ship multilingual or regulated campaigns. I'll be here all day. Ask me anything.

Who hunted SendLint?
SendLint was hunted by Michael. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
