How Inboxes work
Inboxes mirror the familiar email inbox structure, using threads, labels, and drafts to organize your conversations.inbox, sent, archive, trash, and spam folders are built in to your Resend Inbox.
Receiving email in an inbox is different from receiving
emails, which delivers inbound messages
for a domain to your own webhook endpoint. Use Inboxes when you want Resend to
store, thread, and organize conversations for you.
Inboxes features
With Resend Inboxes you can:- Draft and send new emails from a dedicated email address that users can reply to.
- Receive inbound emails and attachments and reply to them in a threaded conversation.
- Forward received emails to another email address.
- Read threads, and move them between

- Search and filter threads.
