How to Check If Email is Active?

Verifying emails through an email validation service is the best way to check if an email is active. This process includes basic syntax checks and then more advanced checks which scan the mail server to verify the inbox can receive new messages. Our email checks also incorporate advanced metrics from consumer data, email marketing software, and similar partners with unique data sets for detecting invalid emails. This comprehensive email analysis process ensures that our system is always providing the best accuracy to validate emails.

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.
