Frequently asked questions
Short answers about the B2B Contact Finder: what it checks, what it costs and where it stops.
All free toolsHow does the B2B contact finder work?
Give Clu a name and a company. It looks the person up across 25+ data providers in sequence, verifies the email via SMTP handshake, and returns the address at 1 credit per verified email.
Why does this tool need an account?
Because a real answer takes a provider lookup and a mailbox check, and those run inside the product. A new Clu workspace starts with 14 days of Pro (up to 3 seats, 250 credits).
Can I find phone numbers with the contact finder?
Yes, inside Clu. A workspace starts with 14 days of Pro (up to 3 seats, 250 credits). Clu's waterfall enrichment found a phone number for 85% of contacts on our 500-lead benchmark.
How is a single-source email finder different from a waterfall?
A single-source finder queries one dataset and returns whatever that dataset holds, so a miss is final. Clu runs waterfall enrichment instead: each contact goes through 25+ providers in sequence until one returns a deliverable result, and the result is verified before delivery. Clu states 98% verified work emails and 85% phone numbers as product specs. Several well-known email finders are sources inside that cascade rather than alternatives to it.
