20 Best Email MCP Servers, Compared (September 2026)

Updated 20 of 2,238 Email servers in the Glama registryRebuilt weekly

The short answer

Most readers should reach for Resend's Email Sending MCP (resend/resend-mcp). It is npm-installable, had 12,786 downloads in a typical week, exposes 103 tools with A-grade descriptions, and had a commit 2 days ago with 43 commits in the last 12 weeks. If you need an agent to read and manage an existing mailbox over IMAP/SMTP instead, MCP Email Server (Wh1isper) is the better answer: it exposes 18 tools for read, send, forward, organize, archive, delete, and tag mail, and had a commit 0 days ago.

Whichever you choose, give it the narrowest access that still works (a read-only credential, a replica, a scratch account), and widen it only once you have watched what your agent actually asks for.

Glama operates the MCP registry these numbers are measured from, and sells MCP hosting and a gateway. No position on this page is paid for. How the registry is built.

The ranking, with the evidence

Each position is a weighted mean of adoption (40%), maintenance (24%), momentum (14%), tool description quality (13%) and trust (9%), multiplied by three attenuators: how directly the server is about Email (named for it, declaring it, tagged with it, or merely mentioning it), whether its repository is still moving, and how much independent evidence of adoption it has. Open the score on any entry to see every number, including the ones marked ≈, which were imputed from the median of the other candidates rather than measured. The maintenance grade on each entry is mostly issue responsiveness, release recency and open security alerts rather than commits, so a recent commit beside a low grade is two different measurements rather than a contradiction.

  • Abandoned but popular: People use it, but its default branch has stopped moving. Fine to keep running, risky to adopt.
  • Community favourite: Widely adopted and still actively maintained.
  • Dormant: Neither changing nor widely adopted. Here because it still matches the search.
  • Emerging: Small audience, growing quickly, maintained. The bet with the most upside.
  • Steady: Maintained, modest audience, no surprises in either direction.

    Best for: AI agents that need disposable local mailboxes for email and SMS: it provides send, receive, reply, and inbox-management tools without a third-party email API.

    The server runs a local mail server and exposes MCP tools for agents to send, receive, reply, forward, search, delete, schedule, and tag email, manage contacts, drafts, signatures, templates, folders, and agent accounts. One requirement to know is that real internet email requires a Gmail/Outlook relay or a Cloudflare custom domain, and administrative tools require a master API key.

    Atomic Mail Agentic

    Community favourite▲ 1
    Atomic-Mail/atomic-mail-agentic ↗

    Best for: Autonomous agents that need to register and run their own inbox with no human setup: proof-of-work signup and JMAP handle registration, reading, and sending.

    Its README documents an MCP client with register, jmap_request, and help operations that wrap Atomic Mail's JMAP API and proof-of-work signup. It depends on a hosted @atomicmail.ai account and Atomic Mail's proof-of-work onboarding.
