Best MCP servers for email marketing

Email marketing from an agent spans two layers: the platform that manages audiences, campaigns, flows, and reporting, and the delivery layer that actually sends and tracks the mail. A capable setup lets an agent segment a list, draft and schedule a campaign, build a flow, and read performance, then send transactional and broadcast email reliably. The right picks depend on whether you are running lifecycle marketing, e-commerce flows, or developer-driven broadcasts. The servers below cover the major email platforms and a developer-first sending layer, each a real MCP server with a verified, current install config.
