Before we begin
Want to protect your data quality before you ever hit send? Thought so.
This Claybook helps you verify email addresses, validate website domains, enrich person and company data, and check for tech stack signals—all from a single email input. By adding a master domain blacklist, you can also automatically filter out bad-fit, risky, or irrelevant domains, keeping your lists clean and compliant.
No more wasting credits or risking deliverability on the wrong leads.
How it works:
- Copy the template to your Clay workspace
- (Optional) Build a custom master domain blacklist in table two
- Customize which tech stack signals to track with HG Insights
- Add email addresses to the first column
- Clay will automatically verify emails, validate domains, enrich company and person data, check for tech stack, and detect job changes
