Receive email
Native inbound accepts application email—replies, support requests and intake forms—inside the project’s regional boundary. It is an application receiver, not a personal IMAP inbox.
Set up receiving
Add a receiving domain. Create a domain with receiving enabled, preferably a dedicated subdomain such as replies.acme.com.
Publish its MX record. Add the MX record shown in the project’s domain page and verify the domain.
Create a webhook. Subscribe to email.received (and optionally email.stored) to receive signed inbound events.
Build for reliable delivery
Verify each webhook against its raw body before parsing it, acknowledge after durable enqueueing, and deduplicate with event.id. That ID is stable across delivery retries; the delivery ID identifies only one attempt. Fetch the message from the regional API when you need its full content or attachments.
