POST
Inboxes are currently in private beta and only available to a limited number of users. The response shape might change before GA.Get early access if you’re interested in testing this feature.Once you have access, upgrade your Resend SDK to use the new methods:
An inbox sends and receives email at an address on one of your domains, such as support@example.com. The domain must belong to the team. Without forwarding, the domain must have receiving enabled, with DKIM and SPF verified and the inbound MX record verified or pending. With forwarding set to true, the domain only needs DKIM and SPF verified for sending.
  • A domain that does not meet these rules returns a 422 validation_error.
  • An address or receiving address that is already in use returns a 409.
  • A team that has reached the inbox limit of its plan returns a 403 validation_error.
  • A blocked account returns a 451.

Body Parameters

string
Internal name for the inbox. Recipients do not see it. Max 64 characters. Defaults to email_address.
boolean
When true, Resend provisions a receiving address so you can receive mail without adding an MX record. Read it from receiving_address with Get Inbox. Defaults to false.
