Example Workflows
Sales Rep Researching a Target Account
> "Tell me about stripe.com, then find their VP of Sales and verify the email."
Claude will chain Company Enrichment -> Domain Search -> Email Finder -> Email Verifier automatically.
Founder Building an Outbound List
> "Find fintech startups in France with 50-200 employees, then get the CTOs' email addresses."
Claude will use Discover to find companies, Domain Search to find contacts, and filter for CTOs.
Marketer Finding Contacts for a Campaign
> "Find marketing leaders at SaaS companies in Germany. Verify all their emails."
Claude will chain Discover -> Domain Search -> Email Verifier, confirming credit usage before verification.
SDR Launching Outreach
> "Add my fintech CTO list to a new sequence with a 3-day follow-up, then start it."
Claude will use Build Sequences to create the sequence, add a follow-up step and message template, and add recipients from your list. Because the introduction email (step 0) has no API yet, Claude points you to the Hunter dashboard to write it, then starts the sequence once it's authored -- confirming before any email goes out.
Credits
| Operation | Credit Cost | |-----------|------------| | Domain Search | 1 credit per 10 results | | Email Finder | 1 credit | | Email Verifier | 1 credit | | Company / Person / Combined Enrichment | 1–2 credits each (plan-dependent) | | Discover (companies & people) | Free | | Email Count | Free | | Leads, lists, sequences, CRM push, saved searches, usage | Free |
Claude will always confirm before running operations that consume credits in bulk, and before any destructive action (deleting leads or lists, or pushing to your CRM).
