Frequently asked questions
How does Sculptor source contacts in bulk?
Sculptor takes your target industry or account list, searches multiple contact-data sources for matching contacts, and runs each result through waterfall enrichment across 150+ providers. It queries providers in sequence until it finds a verified email for every contact, then returns each row with company name and verified email ready for export.
How accurate are the emails Sculptor finds?
Coverage typically lands between 30% with a single provider and 80%+ when Clay waterfalls across multiple sources. Clay also validates each email in bulk before it reaches your sequences, catching bad addresses at the sourcing stage so you avoid deliverability hits. You only spend credits on successful matches.
Can I source contacts in bulk for a whole list at once?
Yes. Paste an account list or type a target industry into the Sculptor prompt and Clay builds the entire contact table in one run. You can also upload a CSV of target accounts. Once the table is built, push company name and verified email rows directly to HubSpot or Salesforce, or export as a CSV for your outbound sequencer.
Is sourcing B2B contact data for cold email legal?
In the U.S., the CAN-SPAM Act permits unsolicited B2B email as long as you include a valid physical address, an honest subject line, and a working opt-out mechanism you honor within 10 business days. Penalties reach up to $53,088 per non-compliant email. In the EU, GDPR Article 6(1)(f) allows B2B outreach under the legitimate interest basis, provided recipients would reasonably expect the contact.
Always check the rules for your specific jurisdiction before launching outbound campaigns.
