Your mailer keeps sending. Mailway handles the rest.
Point your existing SMTP configuration at Mailway, connect the providers you already pay for, and gain a complete delivery record.
Adopting an email gateway sounds like a migration; with Mailway it's a config change. Your application keeps speaking SMTP exactly as it does today, and the diff below is the entire integration. Mailway receives the message, writes it to its queue before acknowledging — the database record and the archived bytes follow within seconds — evaluates your routing rules, and hands it to your first provider.
From there the gateway earns its keep: failed attempts reroute automatically, every step lands on the message's timeline, and the archive keeps the bytes. The interactive demo plays the whole journey in about a minute, including a provider failure and a hold-for-approval, and the quickstart gets a real send through in five. For the due-diligence view — durability, failure semantics, rollback — see the architecture page.
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, with no deploy and 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.
Not 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.

the full comparison →Your email stays
on European soil
EU data residency
Your mail is ingested, routed, and archived inside the European Union, on dedicated infrastructure in Germany. Not "EU region available". EU, full stop.
Encrypted in transit & at rest
TLS on every SMTP connection, both STARTTLS and implicit TLS. Stored payloads compressed and encrypted at rest.
Your keys only
Pure BYOK. Your mail rides your own provider accounts, never pooled with other Mailway customers. 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.
