MailSignal

MailSignal is one of those apps that makes you wonder why it didn't exist sooner. You know that feeling when you've got Gmail, Outlook, work email, and maybe a shared inbox all going at once? You're constantly tab-jumping, losing focus every time you switch. Research shows context-switching kills about 23 minutes of focus per switch. MailSignal fixes that by putting every unread count right on your Windows taskbar—all your accounts, one glance, zero tab juggling.

Connect Gmail personal and Workspace, Microsoft 365, personal Microsoft accounts, and shared mailboxes. Then just click to jump straight to any inbox. The privacy piece is clean: they only access unread counts via gmail.labels and Mail.ReadBasic scopes. They literally cannot see your emails, subjects, senders, nothing. Tokens stay local and encrypted with Windows DPAPI. Nothing touches their servers.

Free tier gets you 2 accounts with 5-minute polling. Pro is $25 one-time—no subscription, ever, free updates forever. That gets you unlimited accounts, 10-second polling, Chrome profile selection, custom sections, and priority support. Single license works on up to 3 machines. That's it. No fluff, no monthly fees, just a small tool that does exactly what it says.

Based in the software-as-a-tool world where things don't need to be bloated. If you're managing more than two email accounts and still tab-switching manually, you're leaving time on the table.
