About Mermail
Mermail provides AI agents with a dedicated email address and wallet, enabling them to autonomously register for services, receive verification codes, process online payments, and maintain receipts. The platform integrates with MCP-compatible agent clients such as Claude, Codex, and OpenClaw, allowing agents to perform web-based tasks like purchasing domains, booking services, or managing subscriptions without requiring human intervention. Users can begin with a Mermail-hosted email address and later transition to a custom domain for production workflows, ensuring scalability and flexibility. The system supports file attachments, automated routing of communications, and retrieval-augmented generation (RAG) for efficient document processing and retrieval. It is designed for AI-native users who delegate routine online errands to their agents while keeping transaction records organized in a dedicated inbox. Mermail emphasizes secure and organized handling of agent interactions, ensuring that all communications and transactions are tracked and retrievable. The platform aims to streamline workflows by reducing manual oversight for repetitive web-based tasks.

Frequently asked questions about Mermail
What is Mermail?
Mermail provides personal AI agents with a private email address and wallet, enabling them to register for services, receive verification codes, make online payments, and maintain receipts while completing web-based errands.
Why does my AI need its own email address?
Many online tasks require an email address for account creation, verification codes, confirmations, receipts, and support threads. Mermail assigns an email identity to the agent, keeping these communications separate from a user's personal inbox.
Why does my AI need a wallet?
AI agents can research and compare options, but many workflows require payment to proceed. Mermail provides a dedicated wallet and card for purchases, subscriptions, and bookings, while keeping receipts tied to the task.
Is Mermail a replacement for Gmail?
No. Mermail functions as an inbox for your AI agent, while Gmail remains your personal inbox. The agent can interact with Gmail or other email providers, but it operates with its own identity and task history.
What tasks can I delegate to my AI agent using Mermail?
Users can delegate online errands such as signing up for tools, purchasing domains, booking services, paying small invoices, tracking receipts, canceling subscriptions, following up with vendors, and handling refund or support emails.
Can I use a custom domain with Mermail?
Yes. Users can start with a Mermail-hosted email address and later switch to a custom domain on paid plans to align the agent's identity with their brand or project.
