Disposable, receive-only email inboxes for AI agents. Create an address, wait for the verification email, and get the one-time code or magic link back as structured fields. Long-polling wait_for_email with sender and subject filters, attachments, sanitised HTML, and restore for later password resets. OAuth 2.1, hosted in the EU, cannot send email.
Official remote MCP server of MailSenpai, the EU-hosted email marketing platform. Connect Claude, ChatGPT, Cursor or another MCP client with OAuth 2.1 and PKCE. 74 tools manage lists, subscribers, segments, templates, draft campaigns and stats, and check email DNS, blacklists and spam. Sends and deletions require explicit confirmation; every call is logged. The same team also offers SMTP Senpai, an SMTP relay and email API for transactional sending: https://en.mailsenpai.com/smtp-senpai/.
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.
Disposable email inboxes for AI agents: create an address, wait for mail, read OTP codes and links.
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
Hosted agent inboxes: read mail, send to owner-approved recipients. Mail is server-readable.
Voidly MCP: research, Atlas score, capabilities; gated Voidpay, Voidmail, Home, board and bounty.
Your agent needs a mailbox of its own — to receive, thread, draft and send, with attachments, without borrowing your personal inbox or your company's SMTP. **What you can ask for** • "Create an inbox for this agent and tell me its address." • "Read the new messages in this thread and draft a reply." • "Send this message with the attachment and wait for the response." • "Search this inbox for everything from that domain." • "Show delivery metrics and the events on this inbox." **How to use it** Point any MCP client at https://mcp.aisa.one/mail/mcp and sign in with OAuth — there is no key to create or paste. 49 tools: create and delete inboxes, list and read messages, raw message bodies, attachments, threads, drafts and draft attachments, send and reply, message search, inbox events, metrics, and list entries — reads and writes. **Why this rather than the source** A real inbox an agent owns, rather than an SMTP credential it borrows from a human. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the contact elsewhere in the catalogue, then write to them from here — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/sales/mcp finds the person to write to.

email59's MCP server lets an agent send email on its own. It signs up by asking for a 6-digit code at an address it can read, then uses the session key for everything else. Mail goes out from a name you choose at email59.com, so there's no domain to verify before the first send. Email is sent from @email59.com and replies aren't received yet.
