Frequently Asked Questions
Everything you need to know about VerifNow.
VerifNow is a real-time API that validates emails, phone numbers and custom form fields before they reach your database. It helps you reduce bounces, block fake accounts, and keep your data clean.
We run multi-layer checks: syntax verification, DNS and MX record lookups, typo detection (e.g. gmail.con → gmail.com), disposable and role-based address filtering, domain reputation signals, and a quality score from 0 to 100. The depth of checks depends on your plan.
