What is Stamp?
Stamp is the pioneering AI-native email client designed to act as your personal AI Secretary, autonomously managing your emails and calendar around the clock. Built for "doers," Stamp addresses the challenge of inbox overload by working proactively, ensuring that when you return, your communications are organized, summarized, and often already drafted, ready for your swift review. It's your intelligent "second brain" for a more productive workday.
Key Features
📧 Autonomous Inbox Prioritization & Summaries: Stamp intelligently sifts through your incoming mail, prioritizing important messages and filtering out the noise. It then generates concise summaries for critical emails and delivers them as notifications, ensuring you stay informed without being overwhelmed.
✍️ Context-Aware Draft Replies: Leveraging your entire mailbox, calendar, and its own long-term memory, Stamp automatically drafts personalized replies to incoming emails. These drafts are rich in context and designed to reflect your unique communication style, saving you significant time.
🤖 Agentic Task Automation: Delegate complex tasks to Stamp's Agent and Composer. Whether it's drafting personalized bulk emails for multiple contacts or cleaning up your inbox by identifying and selecting unimportant messages for deletion, Stamp executes these actions intelligently, allowing you to review and approve.
🗣️ Hands-Free Voice Mode & Web Research: Engage with your inbox on the go using the mobile app's Voice Mode, allowing you to chat with Stamp Agent hands-free. For crafting informed replies, Stamp can access the web, performing deep research across dozens of websites to gather necessary context.
🗓️ Smart Calendar & Label Management: Stamp seamlessly integrates with your calendar, allowing you to schedule or modify events directly through the Agent. Furthermore, you can define plain-English labels for your emails, and Stamp will automatically categorize incoming messages and even perform specified actions based on those labels.
Use Cases
Streamlined Return from Absence: Imagine returning from vacation or a long meeting to an inbox where Stamp has already prioritized, summarized, and drafted replies for urgent emails. You simply enter "Stamp Mode" to quickly approve or reject its actions, catching up in minutes instead of hours.
Efficient Outreach Campaigns: Need to send personalized follow-ups to several clients or prospects? Ask Stamp to bulk-draft emails. It will locate contact information, pull relevant context from past communications, and generate tailored drafts for each recipient, ready for your final approval.
Maintaining a Pristine Inbox: Delegate the tedious task of inbox cleanup to Stamp. Specify what constitutes "unimportant" mail, and Stamp will automatically identify and select those emails for archiving or deletion, providing you with a quick review to keep only what you truly need.
Unique Advantages
Stamp distinguishes itself significantly from traditional email clients and basic AI add-ons by operating as a truly autonomous AI Secretary.
The First True AI Secretary: Unlike tools that merely assist, Stamp is built from the ground up to proactively manage your email and calendar. It doesn't just offer features; it performs tasks on your behalf, acting as an extension of your professional self.
Uninterrupted 24/7 Productivity: Stamp works tirelessly around the clock, even when you're offline or not actively using the client. This continuous operation ensures your inbox is always managed, prioritized, and prepared, offering a level of constant support that traditional methods cannot match.
AI-Native Architecture for Deep Intelligence: Leveraging Large Language Models alongside custom-built AI models, Stamp goes beyond simple automation. Its ability to gather context from your entire digital history (emails, calendar, memories) and even conduct web research allows for highly personalized and intelligent actions, making it genuinely "your second brain" for communication.
Conclusion
Stamp redefines email and calendar management by providing an intelligent, autonomous AI Secretary that works tirelessly for you. By handling the heavy lifting of organization, prioritization, and communication, Stamp empowers "doers" to focus on high-impact tasks.
