# Emailsify

> Emailsify gives AI agents and developers instant temporary inboxes. Receive verification codes and links, then let them expire after 2 hours. Free in the browser; MCP for agents on Pro.

Emailsify provides temporary email inboxes. Mail sent to any @emailsify.com address is readable immediately in a browser with no sign-up, and is deleted 2 hours after it arrives. Paid plans (Pro, Scale) add a hosted MCP server so AI agents can create addresses, wait for verification codes, and read and delete mail.

Key facts:
- Free: browser inbox, no account needed. Pro: MCP server for AI agents ($9/month or $50/year).
- MCP endpoint: https://www.emailsify.com/mcp (Streamable HTTP; OAuth sign-in or Bearer API token).
- Agents can: create an inbox, wait for a verification code or link, read mail, and delete mail.
- Message bodies are returned to agents as cleaned, truncated, untrusted text; waiting for a code returns only the extracted code or link.
- Inboxes are not private: anyone who knows an address can read it. Do not use for sensitive accounts.
