Send the email. Then watch what happens to it.

Sendtera is a transactional email API for developers. One endpoint to send, SDKs for the languages you already write, and a delivery log that tells you where every message actually went — not a number in a dashboard a week later.

No newsletter. One message when your key is ready.

You're on the list.

We'll send your API key to when the beta opens.

POST /v1/emails us-east

One request to send. JSON in, message ID out. React templates, attachments and idempotency keys included.

Every message keeps its own timeline. Queued, sent, delivered, opened, bounced — searchable for 30 days, streamed to your endpoint in real time.

Your domain, your reputation. SPF, DKIM and DMARC set up in the dashboard, on dedicated IPs that aren't shared with strangers.
