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
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.
