You get an email address instantly (or bring your own domain with MX records). When email arrives, MIME is parsed into clean JSON with subject, body (plain + HTML), headers, threading info, and attachments with signed download URLs.
Webhook delivery includes configurable retries and request signing. Alternatively, you can poll via REST API.
Free tier: 100 emails/mo. Paid plans from $9/mo.
One honest limitation: delivery latency is typically a few seconds from email receipt to webhook delivery. Not real-time in the sub-second sense, but fast enough for most integration use cases.
