Transactional email,
sovereign by design.
A European alternative to Amazon SES. The same SMTP you already use, plus a clean REST API, 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 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. Prefer REST? Our own send API is clean and modern. 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 our own clean REST endpoint. Keep the SMTP you have, or move to the API.
Pricing
From €5 a month.
20,000 emails a month, fast pre-send verification included, and unlimited daily sending once warmup completes. Retention control and DMARC monitoring come free, where others charge extra. A dedicated IP is a flat €10 add-on, open to any account.
