About Email Fast
An independent email platform built on one conviction: an email company should be able to prove what it claims.
The premise
The email industry runs on adjectives. "Best-in-class deliverability." "Bank-grade security." "Trusted by thousands." Almost none of it is checkable, many platforms quietly rent the infrastructure they're selling — you often can't tell from the outside — and every security page leans on somebody else's certificate.
Email Fast was built to be the other kind of email company: Email Fast runs its own mail transfer agent, warmup engine, reputation breaker, and per-tenant fair queue — we run these ourselves, with no upstream ESP reselling us your delivery. Every delivery can produce evidence — delivered messages can mint an Ed25519-signed delivery certificate — receiving mail server, TLS details, the server's SMTP response, and timestamps, with the recipient stored only as a keyed hash — chained into a tamper-evident ledger and verifiable without trusting us. Customers who want to go further can hold their own keys, with a revoke that locks us out too. And this website itself runs on the same principle: every factual claim in our copy is checked against a claims ledger at build time, so overstating what we've built is literally a build error.
How it was built
The platform is the work of a small, focused team using modern engineering practice to an unusual degree of rigor: 141 numbered database migrations, with a full fresh-database bootstrap proven, 14 runtime dependencies, and a fail-closed boot guard: production refuses to start if any of 13 load-bearing secrets is weak or a dev default.
We're honest about what small means: no sales floor, no analyst-relations budget, no badge wall. What you get instead is a platform whose architecture answers the questions a badge is supposed to answer — and a security page that states its posture plainly.
The name
Email Fast is what it says: email, sent fast, built fast, verified fast. The domain is emailfast.dev because developers are who we built the first door for — but the platform serves creators and security teams with the same machinery.
