Wait for a yes.
An ACK inbox is a whole mailbox. Your agent receives, threads, drafts, labels and searches mail, and your system hears about every change the moment it happens.
Draft first. Send when a person says so.
The agent writes the reply and holds it as a draft. Someone on your team reads it, edits it if they like, and sends it. Drafts can also wait for a time you set.

Each agent sees only its own mail.
Give a key to the whole organisation, to a pod of inboxes, or to a single inbox. The support agent can't read the finance agent's mail, even by accident.
Bring the history with you.

ACK threads old mail the same way as new mail, skips duplicates, and fires no webhooks, so your agent doesn't answer last year's email. IMAP passwords are used once and never stored.Import an mbox file, a zip of .eml files, or pull from an IMAP server.
