Verification codes, password resets, order confirmations — the emails your users can't miss. Send via REST API or SMTP and it's delivered.
We built the transactional email service we always wanted — fast, reliable, and with none of the complexity.
Built on Amazon SES — one of the most trusted sending infrastructures in the world. Your emails land in inboxes, not spam folders.
A clean, RESTful API that takes minutes to integrate. Or connect any app via SMTP — forums, CMS platforms, game servers, anything. API and SMTP, one platform.
Track every email from send to delivery. See opens (with country), bounces, and failures as they happen — and resend any email in one click.
Authentication is handled from day one — and monitored continuously. We alert you if a record goes missing and block sends until it's fixed.
Go beyond transactional. Send newsletters and bulk campaigns to mailing lists — with blocklist management, open tracking, and per-campaign stats. Premium feature.
No monthly minimums. No overages. No gotchas. Per-email pricing that scales with you — from 100 emails to 100 million.
Get HTTP callbacks for every email event — delivered, bounced, opened, clicked. HMAC-signed for security, with automatic retries and delivery logs.
Store email templates with {{variable}} placeholders. Send via template alias instead of raw HTML — edit content in the dashboard without code deploys.
Queue emails up to 72 hours in advance with a single API parameter. Cancel any time before delivery. Perfect for timezone-aware sends.
Send up to 500 unique emails in a single API call — different content, different recipients, different templates. One request, one response.
Network retry? No duplicate sends. Add an idempotency key to any request and we guarantee exactly-once delivery. 24-hour key window.
Know when every email is opened and every link is clicked. Pixel tracking and link rewriting, toggleable per send or at account level.
