Stop guessing how your emails perform. MailTester.ai instantly analyzes newsletters, campaigns, or community emails, giving actionable insights to boost engagement, open rates, conversions and saving you hours of guesswork.
TL;DR: I m a designer, my friend s a full-stack dev. We created an early beta of Mailtester.ai
At a one day app-building event. Basically a full-day coding plus vibe coding. Send a test email to a unique address and instantly get AI + technical analysis (spammy phrasing, link reputation, SPF/DKIM/DMARC, etc.).
Quick tests work without signup. Register, and you get a workspace with a full history of all your emails.
The problem we wanted to solve? You never really know where your emails end up: spam, promotions tab, or the real inbox. And sometimes they even look like a phishing email from 2012.
