How it works
example.com Verified
Add the SPF, DKIM, and DMARC records we generate, so mailbox providers trust mail from your domain.
POST /v1/emails 202
Send through the REST API, SMTP, or both.
email.delivered 200
Delivered, deferred, bounced, or rejected: each outcome reaches your app by webhook.
203.0.113.24 Active
Move to a dedicated IP when volume grows, so its reputation is yours alone.
Two ways to send
Use the Email API for code your team maintains, and SMTP for apps that already send mail. You can use both on the same account.
curl https://api.prontuno.net/v1/emails \
-H "Authorization: Bearer $PRONTUNO_API_KEY" \
-H "Idempotency-Key: order-1042-receipt" \
-d '{
"from": "receipts@example.com",
"to": "ada@example.com",
"subject": "Your receipt",
"html": "<p>Thanks for your order.</p>"

Transactional email only. Every plan covers mail your product sends because something happened: password resets, one-time passcodes, receipts, order and shipping updates, and account notifications. Newsletters, marketing campaigns, and cold outreach are not supported.
