What Is an Email Validator?

An email validator is a software tool that helps you verify email addresses. Many Internet Service Providers (ISPs) include a built-in email validation feature. Originally known as VRFY, this feature allowed senders to check the validity of email addresses before sending them. Unfortunately, this functionality fell into the hands of spammers and was disabled by ISP administrators after widespread abuse.

Email validation tools check the format and syntax of email addresses. They also make sure that the address in question is a valid mailbox. Using an email validator will take just a second and will ensure that the recipient’s email address is legitimate. Usually, these tools provide a report on their findings, including valid addresses as well as bounced and invalid addresses.

Email validators are a useful part of an email marketing strategy. Performing regular checks on your list can help you boost your sales. This type of software also helps you measure the level of activity on your email marketing campaign. With this tool, you can make sure that your emails are sent to the right recipients and aren’t getting filed into the spam folder.

Another important aspect of email validators is checking domain MX records. They simulate the sending process to verify that an email address exists on the mail server. When this validation fails, the email validator raises a ValueError.
