Integrations
SimpleVerifier connects to Google Sheets, Instantly and Smartlead, and to your own code through the REST API, Node.js and Python SDKs and an MCP server. The Sheets script, API, SDKs and MCP server use your API key, which comes with the paid plans. For any other tool, export the list as a CSV, verify it and import the clean file back.
