Fatmail

Fatmail is email built on a simple idea: your inbox is nobody's business but yours. Most email is scanned, profiled, and monetized. Every message you open reports back. Every newsletter knows when you read it, where you were, and what device you used. Fatmail is built to make all of that impossible. PRIVATE BY DESIGN Your mail is encrypted so that it stays yours. No ad targeting. No content scanning. No profile built quietly in the background. TRACKERS BLOCKED BY DEFAULT Remote images and tracking pixels are blocked before they load. Senders don't learn when you opened a message, how many times you read it, or where you were. NO CONTACTS UPLOAD Fatmail never asks for your address book. Autocomplete is built from your own mail, on your own device. A FAST, CLEAN INBOX Privacy shouldn't mean compromise. Fatmail is quick, quiet, and stays out of your way โ swipe to archive, search that actually finds things, threading that makes sense. BUILT FOR THE LONG HAUL No ads, ever. We make money from people who pay us, not from advertisers who want your attention. Fatmail. Email that forgets you.
