Transactional email, sovereign by design.
A European alternative to Amazon SES. The same API and SMTP you already use, running entirely on EU infrastructure, under EU law.
Why it matters
Your provider's jurisdiction is your data's jurisdiction.
A provider based in the United States can be compelled under US law to disclose data, wherever in the world that data physically sits. For email that carries every signup, receipt, and password reset your customers make, that reach is the risk. onesend keeps no US entity in the stack. The company, the servers, and the payment layer are all European.
Sovereign over your data and our service. Your recipients' own mailboxes, wherever they are, remain their own.
Migration
Switch in an afternoon.
onesend speaks the same SMTP and the same send API you already integrate against. Change four fields, verify your sending domain with a live DNS check, and import the suppression list you built up on SES so you never email a bounced address twice. Run both side by side while you gain confidence.
What you get
Everything you had, and the parts SES keeps to itself.
DKIM, SPF and DMARC
Add the records, run a live check, and see each domain flip to verified.
Browse, search, export
Every suppression with the real rejection reason, the diagnostic SES hides from you.
Automated IP warmup
A managed ramp that builds sending reputation cleanly, without babysitting.
Signed webhooks
Delivered, bounced and complained, posted to you and verifiable with HMAC.
Sending statistics
Volume, delivery, bounce and complaint rates, tracked over time and by domain.
SMTP or REST API
Drop-in SMTP credentials, or a clean send endpoint. Use whichever you already have.
Pricing
Below the incumbents. Sovereign by default.
Well under what Postmark or MailerSend charge for the same transactional volume, with none of the US exposure. Wholesale rates for hosting providers who route their customers through onesend.
