Use cases

What teams use LookValid for

Four jobs that bring teams to LookValid: stopping bad signups, cleaning lists, checking numbers before a send and verifying a new account. Each page shows the checks and a real response.

Fraud prevention
A lookup cannot prove a person is honest, but it can show where a request came from, whether the network is a hosting range or Tor exit, and whether the phone number and email domain fit what the person told you. Those signals let a fraud team route the odd ones to review instead of approving everything.
Lead list cleaning
Run each row through a numbering-plan check for the phone and a domain check for the email, then sort the list by what came back: formats fixed, impossible numbers removed, throwaway and role addresses flagged. Reps then spend their time on rows that are worth a call or an email.
SMS deliverability
Before a send, check that each number is possible in its country, see what number type the plan assigns, and look at complaint history on the number. That removes malformed entries, toll-free and premium-rate numbers and numbers people already report, so fewer messages go to places they cannot land.
Onboarding verification
Check the email domain, the phone number and the connection at the moment of signup, then let clean signups straight through and send only mismatches to a second step. Clean signups go straight through, and only mismatches reach the extra step.
