Check email validation ensures that addresses on an email marketing list are valid and can be delivered to the inbox. It removes typos, syntax errors and addresses that are no longer active. It is a crucial step in maintaining a good sender reputation and increasing email engagement. It also prevents your emails from being routed to spam folders or blocked by ISPs. Most email marketers use a service to validate their lists, and it’s recommended that you do this regularly because emails degrade at a rate of 22 percent per year (HubSpot).

Check Email Validation: Tools and Best Practices

When choosing an email verification provider, consider their accuracy, pricing, feature set, and user-friendly interface. Look for features that can identify disposable and temporary addresses, ping the mail server to verify the address exists, detect catch-all servers and check whether an email is on a known complainer or spam trap list. Many online email verification services can perform bulk verification in a quick and easy process, which is ideal for those with massive mailing lists that need to be cleaned up.
