ai-mail.sh gives your AI agent its own email address for $0.05, paid with x402 (USDC on Base), with no signup. Verification codes and links come back already extracted, and wait holds the request until mail arrives. Addresses are never reassigned: come back months later, pay again, same address. Receive-only, no tracking, and you delete it, it's gone. Works over HTTP or MCP.
Mac & Windows: let ChatGPT, Claude & Cursor use your email, calendar, iMessage, Teams, files. Free.
Let AI agents check whether an email is a real person's work address or a personal, disposable, relay or shared team inbox (info@, sales@, support@), and see which stack the company runs: Google Workspace or Microsoft 365 with tenant ID and identity provider. Every verdict comes with reason codes and an allow / review / block recommendation. Docs: https://isbusinessemail.com/docs/mcp

AgentiSend is a transactional email API: send through verified domains with a message log, budgets, a preflight and refusals that name the fix; built so AI agents can send on your behalf. The hosted MCP server at https://api.agentisend.com/mcp exposes 82 tools (44 on tools/list; the rest via list_more_tools). A send is one message or a batch of up to 500 items with per-item results. preflight_email runs every gate a real send runs, sends nothing, and costs nothing. Every 4xx returns code, message, and fix. There is no tool for unsolicited mail. Auth is a bearer API key or OAuth 2.1 with dynamic client registration. Starter prompts: "Send this receipt to the customer." "Preflight this send and tell me what would stop it." "What can I spend today?"
Send and receive across email, SMS, WhatsApp, and voice. One API, one contract.
Find customers, research each one and draft the outreach. Nothing sends without approval.
