Know when mail is waiting
The Unread Mail key shows a big number of unread emails in the folder or label you pick, green when there is mail and white at zero. Very large counts show as 12k.

Keys show how many emails are unread in Gmail, Yahoo, iCloud and other IMAP mail, and a press opens your mail.

Overview
To see your unread Gmail, Yahoo or iCloud emails on a Stream Deck, add Unread Mail Counter, put its Unread Mail key on your Stream Deck and type your email address and an app password in its settings: the key shows the number of unread emails in your inbox right away, green when there is mail and white at zero, and new mail in the inbox shows within seconds on most servers.
One press opens your mail in the browser, and the plugin only reads: nothing is marked as read, moved or deleted.
Features
The Unread Mail key shows a big number of unread emails in the folder or label you pick, green when there is mail and white at zero. Very large counts show as 12k.

Gmail opens the same label, or a search with the same filters. Yahoo, iCloud and other services open their webmail, or any web address you set for the key.

Each key has its own folder or label, a sender filter (a name or an address), an only-starred switch and, for Gmail, a search such as category:primary.

The unread count with the sender and subject of the newest unread email on the touch strip. Turn to switch accounts, push or tap to open your mail.

The keys and the settings follow the language of your Stream Deck app, and folders named in Japanese are shown in Japanese.

The key says Check password or Offline in plain words, keeps the last count with a small dot while the server cannot be reached or answers with an error, and the settings page says what happened.

Up to 5 accounts, typed in once and shared by every key, each on its own key.
Classic, Neon, Ring, Bars or Solid.
Your addresses and app passwords stay in the Stream Deck app on your PC, out of exported profiles, and go only to your own mail server over an encrypted connection. No server of ours, no tracking.

FAQ
Short answers to what people ask before they add it.
Email contact
Add the Unread Mail key of Unread Mail Counter and type your Gmail address and a Google app password in its settings. The key shows the number of unread emails in your inbox right away and updates within seconds when new mail arrives.
Gmail, Yahoo and iCloud let mail apps sign in only with an app password, made in your account's security settings. It works only for mail apps, and you can remove it at any time without changing your real password.
No. It opens your folders read only and reads the counts and, for the dial, the sender and subject of the newest unread email. Nothing is marked as read, moved, deleted or sent.
Yes. Each key has its own folder or label, a sender filter and an only-starred switch, and Gmail keys also take a Gmail search such as category:primary.
No. Microsoft no longer lets mail apps sign in with a password, so Outlook.com, Hotmail and Microsoft 365 accounts cannot be read by this plugin.
