Email Checker for Gmail™

Email Checker for Gmail is a lightweight Gmail checker and notifier for your toolbar: it shows how many unread emails are waiting in your inbox and alerts you the moment new mail arrives. Outlook is supported too: connect it once and all your mailboxes share one badge, one panel and one set of alerts.\n\nNo more keeping a mail tab open just to check your email. This inbox tracker keeps checking email for you: the badge, the desktop alerts and the side panel answer one question at a glance — is there new mail, and is it worth opening?\n\nWHAT IT DOES\n\n- Live unread counter on the toolbar badge, refreshed every 30 seconds to 5 minutes. The badge can track every unread email in the mailbox, or only the ones listed in the panel.\n- Desktop notifier with a subtle chime: when a new message arrives you get a notification — click it to open the email directly.\n- A minimal side panel to check your Gmail inbox without switching tabs: sender, full subject, preview text and time. Unread emails are bold, mail you have read stays in the list greyed out, just like in Gmail. Click any row to open it.\n- Category filters: Primary, Promotions, Social, Updates — the badge and notifications follow the selected filter, so you can get alerts for Primary mail only and ignore newsletters.\n- Conversation grouping: multiple unread messages in one thread are shown as a single row with a count.\n- Read tracking is automatic: open an email, read it, and within seconds the badge drops and the row turns grey. No manual refresh, no marking anything by hand.\n- Supports up to 3 signed-in Google accounts — the panel and the counter cover all of them.\n- Configurable check interval, notifications and sound each on/off.\n- Optional reminders: if a message you were notified about is still unread, the extension nudges you again every 5, 15, 30 or 60 minutes until you read it.\n- Light and dark theme: follows your system by default, or pick one in settings.\n- Outlook and Microsoft 365 email checker: connect an Outlook.com, Hotmail or work account and its unread mail joins the same list as Gmail, with the same notifier and the same unread counter.\n\nHOW TO USE\n\n1. Install the extension and make sure you are signed in to Gmail in this browser.\n2. Click the icon to check Gmail in the side panel — unread emails in Gmail inbox order, newest at the top in bold.\n3. New mail updates the badge and triggers a desktop notification automatically.\n\nThat is the whole Gmail setup: no account creation, no sign-up forms, no OAuth screens — the extension works with the session you already have. Outlook uses the standard Microsoft sign-in, and the token never leaves your computer.\n\nWHO IT IS FOR\n\n- You wait for an important reply and want a mail check without a Gmail tab pinned all day. The badge tells you when it actually arrives, and the reminder makes sure you do not forget to answer it.\n- You keep asking yourself how to check unread emails in Gmail, or how to find unread emails in Gmail buried under promotions: the panel lists them in one place, newest first, grouped by conversation.\n- You miss the classic Gmail notifier: this email checker is a notifier and mail tracker for Gmail built into the modern browser — one glance at the toolbar instead of another "check my email" round trip.\n- You run several inboxes and check emails across work, personal and a side project: with multi-account support the tracker follows unread mail from each account in one list, and you jump straight to the right message.\n- You get too much mail: point the counter at Primary only, and social or promo messages stop generating noise, while real conversations still trigger an instant alert.\n- You use Outlook or Hotmail as well: this Outlook notifier checks Outlook.com, Hotmail and Microsoft 365 mail from the same toolbar icon — one unread email counter for every mailbox, and no second extension to install just to check Outlook mail.\n\nThe goal is simple: "how do I check my email quickly?" stops being a question. You should not spend the day checking the mailbox to find out there is nothing new. The mailbox should tell you when something worth reading shows up — quietly, through a small number on the badge and a short chime you can switch off at any time.\n\nTIPS\n\n- Pin the extension icon to the toolbar so the unread counter is always visible; the panel opens with one click on the icon.\n- Set the interval to 30 seconds while you wait for something urgent, then relax it back to a few minutes — unread tracking stays accurate either way.\n- Wondering how to see unread emails in Gmail from one category only? Pick the tab in the panel: the badge, the list and the alerts all follow it.\n- The chime is optional: keep visual alerts on and mute the sound for a silent Gmail desktop notifier.\n\nPRIVACY\n\nThe extension tracks your inbox, not you. It reads only Gmail's built-in unread-mail feed (mail.google.com) using your existing browser session — the same mechanism the official Google Mail Checker used. Nothing is sent anywhere: no external servers, no analytics, no accounts, no data collection, no third parties. Message data is displayed and cached locally so the panel can show read mail greyed out; all settings live in your browser and never leave it. Outlook mail is read through the official Microsoft Graph API: the access token is stored only in your browser and is used for nothing but checking your unread mail.\n\nLIMITATIONS WORTH KNOWING\n\n- For Gmail you must be signed in to Gmail in the same browser profile; for Outlook a one-time Microsoft sign-in is needed. Otherwise the badge shows "?".\n- Gmail's feed returns about 20 newest unread messages; the badge count is always exact, and the panel says "Showing X of Y unread" when the rest is not visible.\n\nEmail Checker for Gmail is an independent project.
