SendLint tools
Tools for building and checking emails
Small, single-purpose tools from SendLint’s email QA workflow — for copy decks, links, images, alt text and inbox previews. The subject and pre-header preview works without an account; the rest come with SendLint.
Prepare a deck
Drop any copy deck — Word, Pages, PDF or a designed PDF — plus the links spreadsheet if they live apart. See exactly what SendLint reads, then download it all as one deck in the SendLint layout.
See how it works →Deck compare
Drop two versions of a deck (V27 and V28). See every line that changed, version by version and language by language, so a round re-checks only what moved.
See how it works →Alt text writer
Drop any image — a screenshot, a design export, a photo — and the AI Agent writes accessible alt text the way email teams do: one short sentence on what it shows, a banner's own words, or alt="" for decoration. Or give it a whole email.
See how it works →Link sheet
Paste an email. Every link followed to where it really lands — status, redirects, tracking parameters, error pages and test sites — as a sheet you can export.
See how it works →Subject & pre-header preview
Type a subject line and pre-header and see where each inbox cuts them off, on desktop and mobile, with character counts.
Use it now →Image check
Drop an email. Every image checked — file size, real versus displayed dimensions, retina sharpness, format and missing alt text — with what to fix in each.
