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. The introduction email (step 0) is created empty, so Claude writes its subject and body with Update-Sequence-Follow-Up, then starts the sequence -- confirming before any email goes out. Nothing here needs the dashboard, as long as the sending inbox is already connected.

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).
