Gmail Multi Account Notifier

Checks configured Gmail accounts for unread mail and warns when an account needs sign-in.

Gmail Multi Account Notifier helps people who use multiple Gmail accounts keep track of unread messages from one Chrome toolbar popup. Click Detect accounts and the extension finds the Gmail accounts you are already signed into in this browser, so you do not have to look up slot numbers by hand. You can rename any account, add or remove one, or edit it later. The name you give an account is the name shown everywhere. If an account is signed out or points to a different email, it is shown in red in the popup and on the toolbar badge, so a broken account is visible at a glance without interrupting you. Features: - One-click detection of the Gmail accounts you are signed into - Custom names for each account - Per-account unread Gmail counts - Chrome toolbar badge with total unread count - Click an account to open that Gmail inbox - Chrome notifications for new unread messages, bundled so several accounts never produce a burst of alerts - A single summary notification when you return after being away, instead of one alert per account - Signed-out accounts shown in red rather than as notifications - Light and dark theme support - Local-only settings storage - No external server - No Google Cloud or OAuth setup required The extension uses Gmail's signed-in browser session and Gmail unread feed. It does not collect, sell, transmit, or share your data with any third-party server.
