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, most platforms rent the infrastructure they're selling, 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 — the pipes are ours, not resold. 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, 65 end-to-end verification suites and 351 unit tests, green at every commit, and a 19-stage adversarial security review, run to zero confirmed findings before launch was even considered. That review was internal and adversarial — a documented find→refute→fix→re-verify loop — not a third-party audit. We say exactly which one we have.
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.
