FAQ
How many MCP servers are there for email automation?
Electra Index lists 191 active MCP servers for email automation from the Official MCP Registry. 98 offer a hosted endpoint and 156 publish their source code.
Is there a hosted MCP server for email automation, with nothing to install?
Yes. MailMask, OpenMail and Posylai — AI Email Builder declare a remote endpoint you add to your assistant's MCP settings.
Is there a ready-made AI agent for email automation instead?
Yes. If you prefer a finished product to plugging tools into your own assistant, Apollo.io, Zapier Agents and Jason AI SDR do this out of the box.
How this list is ordered: a tool comes first when the use case appears in its name rather than only in its description, then when it offers a hosted endpoint, then when its source code is public, then by how recently our robot saw it in the Official MCP Registry. The match to email Automation comes from the publisher's description (keyword method), not from a test of the tool. Only active tools with a real description are listed. No tool pays to appear here.
