Send an Email Asynchronously

POST 
/send-async

Queues an email message for asynchronous processing and returns immediately with a request ID.

The email will be processed in the background, and you'll receive webhook events for all delivery status updates (e.g. dropped, processed, delivered, hard-bounced). These webhook events are identical to those sent for the synchronous /send endpoint.

Use this endpoint when you need to send emails without waiting for processing to complete. This can improve your application's response time, especially when sending to multiple recipients.
