Workflow templates with verification built in
9 free templates for the tools sales and marketing teams already use. Each one checks the email address with SimpleVerifier before anything is sent, and says plainly where a person still has to decide. Download an n8n workflow or a Make blueprint, copy exact settings for Zapier and Clay, or paste a prompt into Claude or ChatGPT. The templates are free. The verification step uses your API key.

How the templates work
- Every template calls the same endpoint, the SimpleVerifier REST API, with your key. No key is stored in any file.
- Files are plain JSON or a script you can read before you import it.
- AI steps use your own AI key. The prompts only use the facts in your data and forbid invented news.
- Catch-all addresses are never marked valid, so they stay out of your main campaign unless you choose otherwise.
Looking for ready-made connections instead? See the integrations for Instantly, Smartlead, HubSpot and more, the API docs or the MCP server. For email copy rather than automation, see the email templates.
