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.
What changes on your side: the SMTP host, and the credential your app signs in with. What doesn't: your mailer, your templates, your provider accounts, and your sender domains. Mailway receives the message, writes it to its queue before answering, evaluates your rules, and hands it to your first provider; the database record and the archived bytes follow within seconds.
From there, 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 about five minutes. For durability, failure semantics, and 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 an HTTP API.
Paste in the keys you already have
Add your provider API keys, assign them to projects, and pick how each project chooses a provider: fallback (a fixed order), free-first (providers with free allowance left go first, counted approximately), round‑robin (each provider in turn), or random (the default). All from the console, with no deploy and no DNS changes.
Mailway takes it from here
Mailway handles routing, retries, suppression, and the archive. Switching providers never touches your code again.
Not another provider
Mailway doesn't replace Amazon SES, SendGrid, Postmark, or any other provider you use. Your provider accounts, keys, and sender domains stay yours. Mailway sits in front of your providers and adds one thing: the record.
- Provider accountsfor example Amazon SES, SendGrid, Postmark
- Provider keyscreated in your provider account, stored encrypted
- Sender domainsverified at your provider
- Sender reputationnever pooled with other Mailway customers
- Provider pricingbilled to you, no markup
- Your mailerover SMTP, only the host and SMTP credential change
- An exact copy of every email your app sends: its Sent folder.
- Every provider's answer, and delivery events where the provider reports them.
- Failover when a provider refuses, on Pro and up.
What Mailway stores
stays on European soil
EU data residency
Your mail is received, routed, and archived inside the European Union, all in Germany: the servers in Falkenstein, the archived messages in Frankfurt (AWS S3). Not an optional EU region: the only one.
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, 889,000+ messages, 99.9% accepted by a provider after failover.
one EU region today, with additional regions on the roadmap as we grow
