How it works
Send emails via API

Integrate in minutes by simply passing JSON data through API endpoints.

Test, debug, and preview emails with sandbox API endpoints.
Build templates visually

Use the data from API calls to drive content and logic without a single line of code.
–
Make design and content changes without re-deploys.

Build freely knowing your emails will render well across clients (yes, even Outlook).
Land in inboxes, not spam
–
Send confidently via world-class AWS infrastructure.
–
Scale to sending millions of emails on auto-pilot.
–
Enjoy high deliverability rates without paying for a dedicated IP (we manually review each sender).
Monitor every send
–
Track detailed logs, including opens and clicks.
–
Filter and search across email activity.
