# email.replied

> Fires the first time a recipient replies to an email you sent.

The `email.replied` event fires the **first time** a recipient replies to an email you sent. The reply arrives as an inbound message on one of your receiving domains and is matched back to the original send (via its threading headers, or the latest email sent to the replying address).

Repeat replies to the same email do **not** re-fire the event — each reply is still stored as its own received email (with an `email.received` event) and linked to the sent email via `reply_to_email_id`.
