How to Detect Invalid Emails?
Email checking is a necessary step for email marketers and websites collecting email subscribers online. Identifying invalid emails can prevent email bounces, which improves reputation around a sending IP or domain. Email bounce rates are critical to monitor for email marketing campaigns. If an email campaign has a high bounce rate, the mail service provider may penalize the IP or domain by routing future email content to the SPAM folder. To further increase trust scores and reputation signals, use our email SPAM tester to verify your email content is friendly for inboxing.
How To Check if An Email Address is Compromised?
Email reputation scores can quickly change as emails are frequently exposed by data compromises and database leaks. IPQS dark web leak search monitors leaked emails online through our Dark Data™ program. Email addresses exposed by these data breaches are commonly used by hackers and malicious users for new account creation fraud and suspicious activity.
