Data Quality & Verification Suite — Clean and verify contact data with one API: validate email addresses (single and batch), verify phone numbers, parse and standardize postal addresses, validate domains, check URLs, and classify IP addresses. Stop bad data at the door.
✅ Rules + lookups
🚀 Newcomer launch pricing — limited-time introductory rates while we earn our first reviews.
Built for sales-ops, CRM admins, data-engineering and growth teams, fraud and onboarding teams.
Why this exists
Dirty contact data — invalid emails, fake phones, malformed addresses — wrecks deliverability, CRM hygiene, and onboarding, and the checks come from separate single-purpose vendors.
What you get
One API key validates and standardizes every contact field — email, phone, address, domain, URL, and IP — at form-submit time or in bulk.
