Receive emails and get structured JSON with bodies, attachments, and headers parsed automatically, plus authentication checks.
Create, personalize, and send newsletters and product launches with a markdown-based email builder, dynamic segmentation, and domain warmup.

Give every AI agent a real inbox and one API to use it

Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support.
