Email infrastructure for AI agents. Connect your coding agent and it sets up email in your app: create templates, segments, workflows and webhooks, send test emails and read back what was delivered, track events, and create agent inboxes. Sign in with OAuth or use a Volanea API key. Test keys render and log but never deliver. 1,000 emails free every month.
Never-stored live email: read, send and triage Gmail, Outlook / Microsoft 365, or any IMAP mailbox.
Disposable test inboxes for agents: create an address, then wait for its code or link.
Free SEO & AI-search (AEO) audits for any site or Shopify store, with emailed weekly score reports.
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.
Gmail, Outlook, Hotmail, iCloud and Fastmail at once: search, read, draft, send and organise mail.
MailBeast.ai is a cold email outreach platform. This server lets AI assistants create and launch campaigns with multi-step A/B sequences, manage leads and sending mailboxes (health, warmup, limits), read and answer replies from a unified inbox, and pull campaign analytics. OAuth 2.1 sign-in with read-only or read-and-write access; an API key header is also supported. Website: https://mailbeast.ai
Find and qualify B2B leads, manage outreach campaigns, and prepare replies through Funkel AI. Supports LinkedIn, X, and email workflows. Tool discovery is public. Tool calls require OAuth or a personal access token.
Hosted email MCP for your own Gmail, Outlook.com, Microsoft 365, iCloud or IMAP inbox: read, search, draft, reply in thread, forward and file mail. It moves or flags up to 500 messages in one call, and a send leaves exactly one copy in Sent. A calendar is a separate connection, and connecting one adds diary and scheduling tools.
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.

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

CRM for one-person businesses. Sends texts and email through your own accounts, runs campaigns and workflows, issues invoices. OAuth or API key.

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.
