Paubox Receiving lets you accept inbound email via the Email API. Provision a domain, and pull messages and attachments via REST, with no mail server to run.

​
How it works

  1. Enable inbound email. A receiving domain is automatically provisioned as a subdomain of inbound.paubox.email (e.g. gentle-dolphin.inbound.paubox.email). A catch-all inbox handles mail to any address on the domain.
  2. Receive email. Anyone can send to any address on your domain. Messages are stored and available via the API within seconds.
  3. Retrieve messages. List, read, and download attachments through the API. Cursor-based pagination keeps large inboxes fast.
  4. Get notified. Subscribe to the email.inbound.received webhook event in the Paubox Dashboard to receive a POST to your endpoint each time an email arrives. The Webhook Endpoints API doesn’t accept this event, and it isn’t yet available on every account; see Webhooks.
