Email is the only software deployment where teams are expected to cross their fingers and pray nothing breaks. You test your web app, lint your codebase, and automate CI. But the moment an email is sent, you are left hoping that Gmail's dark mode will not invert your logo, that the 102KB clipping limit will not butcher your footer, and that desktop Outlook clients will not destroy your layout. The traditional approach has been to pay expensive subscriptions just to wait minutes in slow screenshot queues and run manual checks after the fact. Emailens treats email compatibility like modern static analysis: fast, automated, and pre-send. It flags layout regressions, unsupported properties, and inbox quirks in milliseconds before an email ever ships. • Open-source engine: https://github.com/emailens • Web app: https://emailens.dev
