Frequently Asked Questions
Email verification is a process to confirm that an email can be delivered without actually sending an email. It includes checking that the email address is correct and active, as well as identifying potentially dangerous email types.
Email lists naturally degrade over time as people change jobs, switch email providers, abandon inboxes that then fill up, or simply enter their address incorrectly. Regular email verification helps keep your list healthy by identifying and removing expired, invalid, or risky addresses before they hurt your deliverability.
Using an email verification service allows you to remove expired, misspelled, temporary, disposable, invalid, and risky emails from your list. This will protect your business from high bounce rates, protect your reputation with email providers, and reduce the chances that your email goes directly to spam.
