Stamp
Stamp
Stamp is an AI-native email client designed to automate and streamline inbox management by acting as a personalized “second brain” that handles emails, prioritization, and task tracking with minimal user effort. It integrates directly with existing email providers and uses artificial intelligence to automatically draft replies in the user’s own voice by analyzing past messages, context, and communication patterns, producing responses that closely match the user’s tone and intent. It continuously organizes incoming emails by applying intelligent labels based on plain-English rules, grouping related messages, and filtering out low-priority content so users can focus only on what matters most. Stamp also generates real-time summaries for every email, allowing users to understand key information without reading full threads, while simultaneously extracting and tracking action items to ensure follow-ups are not missed.Starting Price: $20 per month -
