sender/post

Tool: create

Create a new sender (email account).

Creates a new sender identity that campaigns can use to send email. Returns the created sender object on 201. See schemas/sender for all response fields.

Creation is accepted without verifying connectivity. SMTP/IMAP credentials are not tested at create time — the 201 carries connection_state: "validating", not disconnected/recent_error_count (validation runs async, not yet run). Re-read via sender/get_by_id after ~15 s: healthy only when disconnected is false AND recent_error_count is 0. A fresh row in sender/errors_by_id is the authoritative bad-credentials signal and can land within seconds (3–8 s observed), but an empty error list read before that wait has elapsed proves nothing — wait and re-check rather than reporting the sender connected. See schemas/sender for connection state semantics.

replyTo caveat: if set, Unibox will not catch replies unless the reply-to address is also connected as a sender.
