What is an Email Checker Tool?

An email checker, or an email verification API tool, is widely used to validate email addresses and guarantee their authenticity. Simply put, it helps you check that an email address exists and can receive emails. An email verification tool is crucial before reaching out to new recipients to help you reduce the high bounce rate and protect your sender’s reputation.

These tools use various email data points such as email format, domain information, and mail servers’ response to determine the validity of an email address. Depending on their uses, email checker tools are sometimes called email testers, email verification apps, and email verification tools.

Although there are other email tools like email finders, email guessers, and email extractors, email checkers differ because they improve your email campaign’s delivery, open and response rates. For your understanding, here’s what the three tools mentioned above mean.
