Use your API key to submit an email. Sendy returns a job ID you can use to check its status.

Email belongs in your product.
The sending infrastructure is on us.

Keep your application focused on what happens next. Sendy handles the work between an API request and a send attempt.

A straightforward integration
Send plain text or HTML with HTTP and JSON. Use a separate API key for each application.
Requests that survive retries
Emails enter a persistent queue. Idempotency keys keep repeated API requests from creating duplicate jobs.
Know where the send stands
Inspect queued requests, sending attempts, and provider acceptance. Temporary failures retry automatically.
