Mail7

Integrations

Integrations, plugins and SDKs

Put Mail7 email validation where you already work. Ready-to-install plugins for popular mailing tools, an MCP server for AI assistants, official SDKs for developers, and one simple REST API.

Everywhere, the same three answers

Valid Not Valid Unknown

Every integration keeps Mail7's honest three-way result, so an address that simply can't be confirmed is never wrongly rejected. Plugins block only confirmed-invalid addresses and fail open when a check cannot run.
