The exact message, years later.
Mailway keeps what your app sent, from HTML and text to headers, attachments, and the original DKIM signature, then makes it searchable by sender, recipient, subject, and state.
Transactional email usually vanishes at the moment of sending: the app hands the message to SMTP, the provider answers 250 OK, and no copy exists anywhere on your side. Mailway archives every outbound email exactly as submitted, including HTML and text bodies, headers, attachments, and the original DKIM signature. All of it stays searchable by sender, recipient, subject, and state.
Retention follows your plan, from 30 days on Free to unlimited on Enterprise, with multi-year add-ons for SOX, HIPAA, and FINRA record-keeping; the retention docs have the details. A delivered mail can become signed proof of delivery, and where the stored bytes still carry the sender's DKIM signature, the certificate binds that in too.
Your app doesn't have a sent folder.
Mailway gives it one.
Every mail client keeps what you send. Your app sends the more consequential mail and keeps none of it: receipts, reset links, and contracts vanish the instant SMTP takes them. Mailway archives each message exactly as sent, searchable by sender, recipient, subject, and state. So when finance asks about an invoice from last March, you open the email itself instead of a log line that mentions it.
of Delivery
"I never got that email."
Here's the receipt.
Every message is archived with its raw MIME and original DKIM signature, and can be turned into an Ed25519-signed proof-of-delivery certificate, countersigned by an independent time authority so it can't be back-dated. The signature verifies in anyone's browser, so there's no need to trust our database, and the timestamp doesn't even trust us. Share the rendered email itself with a private mailway.to link, and settle the dispute instead of having it.
90 days on Pro, 6 months on Team, 1 year on Business, unlimited on Enterprise, with 3-to-7-year add-ons for SOX, HIPAA, and FINRA record-keeping. All of it EU-hosted, all of it searchable.
