# Overview

**Connected mailboxes are the email accounts your team has connected to Allegrow for sender reputation monitoring.** Someone on your team connects a mailbox through the Allegrow app, and from then on Allegrow continuously measures how reliably that mailbox's email reaches the primary inbox — rather than spam or the promotions tab.

Each mailbox carries two things you'll see throughout these endpoints:

* **Reputation** — a 0–100 score of inbox placement, tracked daily. This is the same figure your colleagues see on the *Performance* and *Leaderboard* screens in the app. A new mailbox starts reporting a few days after connection.
* **Connection status** — whether Allegrow's link to the mailbox is currently healthy. `connected` means monitoring is active; `disconnected` or `credentials_error` mean the owner needs to reconnect it in the app before fresh data can flow.

Each mailbox is normally owned by a [user](/reference/users-overview) in your workspace — `owner` can be `null` if that user has since been removed — and its sending domain rolls up into the [Domains](/reference/connected-domains-overview) view.

One distinction worth knowing before you build: these are **not** the same population as [Safety Net mailboxes](/reference/safety-net-overview). Connected mailboxes are accounts your team plugged into Allegrow for monitoring; Safety Net mailboxes are synced automatically from your sales-engagement platform. A mailbox can be in both lists, either, or neither.

Start with [List Connected Mailboxes](/reference/list-connected-mailboxes) for the workspace-wide view, then [Get Connected Mailbox](/reference/get-connected-mailbox) for one mailbox's day-by-day reputation history.
