Verify any email address is valid is a critical factor in the success of any digital marketing campaign. If a large percentage of your emails bounce (or are marked as spam), it can damage your sender reputation, lead to your emails being blocked, and cause you to lose potential customers. To improve your deliverability rates and ensure that all your messages reach the right inboxes, it’s important to validate every single email address before sending a single message.

Using an online tool such as Abstract is one of the most effective ways to verify any email address is valid. This tool will run multiple steps to determine if an email address is a valid, a typo, or a fake, and it will also check that the syntax of the address is correct. For example, an email address must consist of a local part and a domain, separated by a dot.

How to Verify Any Email Address is Valid: Tips and Tools

Aside from syntax checking, the Abstract email verification process will also ping the address to make sure that the mail server exists. The tool will return a status code for each ping. A positive status code means that the server is accepting mail, while a negative status code means that the server is down or that the email address doesn’t exist.

Although this is the quickest and easiest way to validate an email address, it’s not very accurate. It’s also inefficient for marketers who have extensive lists of email addresses to check, especially when many of these addresses are dormant or have changed jobs. To avoid the problems associated with this approach, it’s a good idea to use an automated tool that checks the validity of each and every email address in your list on a regular basis.
