About Mermail
What the tool does and who it's for
Mermail provides dedicated email identity, communication, and payment infrastructure for AI agents. It allows autonomous agents to perform real-world online tasks beyond simple chat by giving them persistent email addresses and virtual wallet credentials. Agents can sign up for services, receive verification codes (OTPs), execute web payments, manage subscriptions, organize receipts, and engage in two-way support threads. Designed for agentic workflows, Mermail integrates seamlessly with tools like Claude, ChatGPT, Codex, Cursor, and OpenClaw via Model Context Protocol (MCP), Skills, SDKs, and REST APIs.
