Pidgeon and the alternatives
Where Pidgeon fits next to the tools developers already reach for when an agent needs email — and where one of them is the better choice.
Agent inbox APIs
Built for the same job: an address the agent owns.
Transactional senders
Built to send mail from an app. Receiving is a webhook, not a mailbox.
Pidgeon vs Resend
Resend is a sender that has learned to receive; Pidgeon is a mailbox that also sends. Here is which one an agent needs, and when to use both.

Checked
