curl -X POST https://api.do.dev/v1/send/emails/send \
-H "Authorization: Bearer do_live_..." \
-H "Content-Type: application/json" \
-d '{
"from": { "email": "hello@yourdomain.com", "name": "Your App" },
"to": ["user@example.com"],
"subject": "Welcome aboard!",
"html": "<h1>Thanks for joining</h1>"
}'Features
Everything you need to deliver email
Transactional email for developers who need reliable delivery without babysitting an SMTP server.
Send from your domain
Verify a domain once and send from any address on it. We generate the SPF and DKIM records; you paste them into DNS.
Delivery logs
Every message tracked from queued to delivered, bounced, or complained — with the SES diagnostic attached.
Suppression handling
Hard bounces and complaints are suppressed automatically so your sender reputation stays intact.
Compliance built in
GDPR and CAN-SPAM friendly by default. Per-tenant reputation isolation keeps one customer's mistake off your domain.
Ownership verification
Domains prove ownership to send.dev with a TXT record before sending is unlocked — no lookalike-domain abuse.
Developer first
Plain REST with JSON. Reusable templates with variables. One API key for every do.dev product.
Simple integration
Start sending in under 5 minutes
Create an API key, verify your domain, and POST one JSON body. That is the whole integration.
- Plain REST — no SDK to install
- Bearer token auth with one do.dev API key
- Queued in under 100ms, delivered in seconds
- Delivery, bounce, and complaint events in your logs
