Best Practices for Email Verifications

Prioritize active emails to improve open rates and engagement levels
Verify domains to identify fake or inactive email addresses before sending
Remove duplicate emails from your list before verification to avoid unnecessary processing
Retest unknown email addresses after 24 hours to improve accuracy
Exclude spam traps to protect your sender’s reputation and email deliverability
Segment catch-all emails before sending campaigns to reduce bounce rates
Validate email syntax to detect formatting errors and prevent invalid entries
Verify MX records to confirm the email domain is capable of receiving messages
Flag high-risk emails to minimize fraud and security threats
Test small batches of emails before launching full-scale campaigns to detect issues early
