About

Stamp AI is an AI-native email client that acts as an AI secretary for professionals overwhelmed by inbox volume — automatically filtering, prioritizing, composing, and sending emails in the user's voice, tracking action items, and managing calendar interactions without requiring the user to manually triage every message. Built on the insight that employees spend 25%+ of work time in email and 4 billion people globally check email daily for an average of 6+ hours, Stamp positions itself as the first email client designed from the ground up for AI assistance rather than as a traditional email client with AI features bolted on.
