Problem
Email inboxes are cluttered with newsletters, receipts, promotions, and notifications that bury important messages from real people. Users struggle to triage incoming mail efficiently and often miss critical correspondence amid the noise, while unwanted bulk senders continue to fill the inbox with content the user never reads.
Solution
MailTag automatically assigns user-defined category labels to every incoming email as it arrives, directly within existing email clients like Gmail, iCloud, or any IMAP inbox. Users write plain-language category descriptions once, and MailTag uses self-hosted open-weight AI models to classify each message in memory without storing email content. The platform also labels historical mail retroactively, and provides sender analytics that show which bulk senders are rarely opened. One-click unsubscribe, archive, spam, and custom sender rules give users direct control over their inbox flow, while all processing happens on the company's own servers in Germany.
Target Audience
Primary users are individual professionals, small business owners, and productivity-focused email users who handle high volumes of incoming mail and want automated organization inside the email client they already use.
