How to choose between them

Emailmd ranks #1 on the installs + stars + recency blend; Email MCP has the most raw installs (39,767 last month) if adoption is all you weigh. 3 of these 15 offer a remote endpoint (no local process to run); the rest are local stdio servers. 5 document no required env vars - paste the config and go; the others need env vars set first (each page lists exactly which). Where we've compared two of these head-to-head, the comparison is linked on each one's page.
