Transactional Email

Transactional email that belongs in your inbox.

One POST call sends password resets, receipts, and notifications. Full message history stored. Real-time delivery webhooks. Idempotent sends. All on the same platform as your marketing campaigns.

Simple API

One POST call to send.

No complex SDKs. Bearer token auth. Works with any language or framework.

// Send a transactional email POST /api/tx/v1/send Authorization: Bearer tx_your_api_key { "to": "user@example.com", "from": "you@yourdomain.com", "subject": "Your receipt #9001", "html": "<p>Thanks for your order.</p>", "idempotency_key": "order-9001" } // Response { "status": "queued", "message_id": "d5201056-b486-407a-..." }
What's included

Everything you need for reliable transactional sending.

Streams & API keys

Organize sends into streams — password-reset, receipts, alerts. Each stream gets its own API key for security and monitoring.

Full message history

Every message body and delivery event stored and searchable. See exactly what went out and when — crucial for debugging.

Open & click tracking

Track engagement on transactional emails just like marketing campaigns. Know when receipts are opened or links are clicked.

Delivery webhooks

Real-time delivery events pushed to your endpoint — delivered, opened, clicked, bounced, complained. HMAC-signed.

Suppression management

Per-stream suppression lists. Automatically suppress bounces and complaints before they damage your sender reputation.

Idempotent sends

Pass an idempotency key and we guarantee exactly-once delivery — even if your server retries. No duplicate receipts.

Template management

Store HTML templates server-side and reference them by ID. Update without deploying code.

Same platform as marketing

One login for marketing campaigns and transactional sending. Shared contacts, shared deliverability infrastructure.
