MailFoundry drafts, personalizes and optimizes your entire outreach — then warms your inbox and scores deliverability before you hit send.
Trusted by outreach teams at fast-moving companies
One platform that handles the writing, the testing and the technical plumbing that usually wrecks outreach.
Describe who you're reaching and what you offer. MailFoundry writes a complete, personalized email in your tone — opener, value, social proof and a CTA tuned to your goal. No blank-page paralysis, ever.
Auto-generates subject-line variants and routes traffic to the winner so your open rates climb on autopilot.
Gradually builds your sending reputation in the background, so your campaigns land in the inbox — not in spam.
Every draft is scanned for spam triggers, length and tone — with a live score before a single message leaves the door.
Build follow-up sequences that pause the moment a prospect replies. MailFoundry watches your threads, stops the bots, and hands warm conversations straight to a human — so nobody gets that awkward "did you see my last email?" after they've already said yes.
Fill in a few details, pick a tone, and watch MailFoundry write a ready-to-send email — right here in your browser.
No signup needed — this is the real engine, simulated client-side.

MailFoundry started with a simple frustration: great salespeople were spending their best hours fighting blank pages and spam filters instead of talking to people.
So we built a forge. A place where a rough idea goes in one end and a polished, personalized, deliverable email comes out the other — in seconds. We obsess over the unglamorous stuff (warm-up, reputation, reply detection) because that's what separates outreach that works from outreach that gets buried.
We're a small, independent team based in Noida, India, building in the open and shipping fast. Our promise is boring on purpose: software that respects the human on both ends of the email.
Pintu Kumar is the founder and CEO of MailFoundry, on a mission to make great outreach effortless for every growing team. Before MailFoundry, Pintu spent nearly a decade in sales and growth roles, where he watched talented reps burn entire afternoons rewriting the same cold emails and chasing replies that never came. He became convinced the problem wasn't effort — it was tooling. In 2024, working out of his apartment in Noida, he began prototyping an AI engine that could draft, personalize and optimize outreach the way a seasoned copywriter would, but in seconds instead of hours. That prototype became MailFoundry. Pintu is a self-taught engineer with a background in computer applications, and he still writes code alongside the team most mornings. He believes deliverability and authenticity matter far more than raw volume, and he's stubborn about building software that respects the people on both ends of an email. When he isn't shipping features or reading customer feedback, you'll find him mentoring first-time founders in India's startup community, tinkering with home-lab hardware, and hunting for the perfect cup of filter coffee.
