How it works

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.

Try the interactive demo Join the waitlist

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 — the diff below is the entire integration. Mailway receives the message, stores it durably before acknowledging, 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 — including a provider failure and a hold-for-approval — in about a minute, and the quickstart gets a real send through in ten.

How it works

The whole migration
is a config change.

the migration — mailer config

const transporter = nodemailer.createTransport({

- host: "smtp.sendgrid.net",

+ host: "smtp.mailway.net",

port: 587,

auth: { user, pass },

});

01connect

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.

02configure

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.

03relax

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.

The difference

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.

Without Mailway

Hardcoded to a single provider

Provider goes down = your emails stop

Switching providers means a code change

No single view of what was sent

Each provider only knows its own bounces

Days of retention, nothing to show a dispute

Locked into one provider's pricing

With Mailway

Route through any provider — or all of them

Automatic failover, mid-send

Switching is a dashboard action

Every email searchable, with a full timeline

Outcomes pool — a bounce learned once protects every provider

Months-to-years archive + signed proof of delivery

Free tiers spent first, volume spread across providers

Built in Europe

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.
