The Problem

Product-led growth companies depend on email for critical user communications including signup confirmations, onboarding sequences, feature announcements, and billing notifications. However, fake or mistyped email addresses during signup create cascading problems: users never receive onboarding emails, support tickets pile up from users who can't access their accounts, and marketing metrics become unreliable due to invalid addresses inflating user counts. High bounce rates from invalid addresses damage sender reputation, causing legitimate emails to land in spam folders. The result is poor user activation, inflated churn metrics, and deliverability problems that affect the entire customer base.

The Solution

Snov.io's Email Verification API enables PLG companies to validate email addresses in real-time during signup, preventing invalid addresses from entering the system. The API integrates directly into registration flows, checking each email against Snov.io's 7-tier verification process before account creation completes. Invalid, disposable, or risky addresses are flagged immediately, prompting users to enter correct information. For existing databases, bulk verification identifies and segments invalid addresses for cleanup or re-engagement campaigns. The verification process checks syntax, domain validity, MX records, SMTP response, and mailbox existence, catching everything from typos to intentional fake addresses. Integration with marketing automation ensures only verified addresses receive campaigns, protecting sender reputation.
