Email validation is a process that ensures that the email addresses in your marketing list are active, reachable and free of spam traps and catch-all addresses. A high number of invalid addresses can affect your ROI, increase hard bounce rates and even result in your messages being reported as spam, marked as junk or placed on blocklists, harming your reputation and making it more difficult to reach your audience.

An effective validate emails verification tool will check that the address is in the correct format and that it has a valid domain. It will also look for syntax errors and verify that the address can accept incoming mail. In addition, it will search the internet to determine if the email exists and is on a valid server. It will also check for catch-all addresses (invalid or not-existing email accounts) and spam traps (real-looking but invalid email addresses used by email service providers and anti-spam groups).
