Sender field requirements for Email activities

We fixed a bug in the Email API that previously allowed creating emails without a sender in cases where a sender is required.

The sender field is required for emails with status inbox, scheduled, outbox, or error. It may be omitted in the following cases:

  • For draft, since the sender can be specified later before sending.
  • For sent, where it defaults to the email address of the user associated with the email or the owner of the API key.

When updating a draft’s status to scheduled or outbox, the sender field is now required if the email doesn’t have one yet.
