Sending messages to fake emails or invalid addresses doesn't just waste resources—it damages your email sender reputation and reduces the overall performance of your email campaigns. Poor data quality results in high email bounce rates, delivery failures, and increased spam complaints, which can move future messages to the spam folder even when the remaining addresses are valid.

These issues can easily be solved with email validation and best practices for email hygiene. By applying a high-quality email checker like the IPQS email database before sending a campaign, you reduce bounce rates and prevent bad email addresses from entering your database in the first place. The result is a cleaner email list, better inbox placement, and higher email deliverability rates for your organization.

Every email address in the database comes with detailed signals tied to risk, format, and behavior. These include indicators for fake email address patterns, disposable email providers, automated sign-up attempts, and domains associated with frequent spam complaints. Your systems can apply email fraud detection and activity signals immediately to assess email validity at the point of collection or during large-scale data audits.

The Email Verification Database supports precise evaluations of individual entries, allowing you to flag incoming emails with issues ranging from temporary inboxes to invalid format or improper configuration with an email server.
