Every emailyour app sends,accounted for.
Point your SMTP config at Mailway and keep sending the way you always have. Behind it: automatic failover across your providers, a delivery timeline for every message, and an archive that can prove what you sent — years later, if it comes to that.

Bring your own keys — the providers you already pay for
Works with Amazon SES, SendGrid, Mailgun, Postmark, Brevo, Mandrill, Gmail, and any SMTP provider.
The whole migration
is a config change.
Point your app at Mailway
Swap host, port, and credentials in the mailer you already use — Nodemailer, Laravel, Rails, smtplib, whatever ships your mail today. 7 SMTP ports open, so it works even where your cloud blocks the usual ones. Prefer HTTP? There's a REST API.
Paste in the keys you already have
Add your provider API keys, assign them to projects, pick failover, free-first, round-robin, or random per project. All from the dashboard — no deploy, no DNS archaeology.
Mailway takes it from here
Routing, retries, suppression, logging, archive. The next time someone asks about an email, you look it up instead of guessing — and switching providers never touches your code again.
One gateway.
Four pillars.
Mailway sits between your app and the providers you already pay for. Each handoff becomes resilient, observable, and provable.
Product overviewAn archive for every send
Search the exact HTML, text, headers, recipients, and attachments your application handed off.
Explore the archive02Failover without a redeploy
Keep multiple providers behind one endpoint. Mailway routes around timeouts, outages, and billing failures.
See provider failover03One inspectable timeline
Follow a message from SMTP receipt through rules, provider attempts, acceptance, and delivery events.
Inspect observability04Proof that survives the dispute
Create a signed, independently verifiable record of what was sent and when it left your system.
See delivery proofSend one email through the whole system.
Pick the route, fail a provider, hold the send for a person's approval — and watch the record write itself. Browser-only; nothing real is sent.
Open the demoNot another provider
Mailway doesn't replace SES, SendGrid, or Postmark. It sits in front of them and makes them interchangeable — which changes what they can do to you.

Your email stays
on European soil
EU data residency
Ingested, routed, and archived inside the European Union, on dedicated infrastructure in Germany. Not "EU region available" — EU, full stop.
Encrypted end to end
TLS on every SMTP connection — STARTTLS and implicit TLS. Stored payloads compressed and encrypted at rest.
Your keys only
Pure BYOK. Mailway never sends from shared IPs, so nobody else's spam problem can ever become yours — your reputation stays yours.
Proven in production
5+ years of real customer volume, 865,000+ messages, 99.6% provider-accept rate. Not a weekend project.
one EU region today — additional regions on the roadmap as we grow
Your mailer config has
one line to change
Mailway is in private beta — we onboard teams one at a time. Leave your email and we'll send your invite when it's your turn.
