Every channel, one API
Send transactional email, SMS, push, and web push from a single API — with one template store, one set of webhooks, and no provider lock-in.
Transactional email that lands in the inbox — receipts, password resets, verifications, and alerts. Send on built-in infrastructure or route through Amazon SES, Postmark, SendGrid, or SMTP with no lock-in.
- Templates managed in a dashboard, edited without a deploy
- SPF, DKIM, and DMARC handled for you
- Webhooks for delivery, bounces, and complaints
SMS & alerts
