The Best Methods to Validate a List of Email Addresses

There are many ways to validate an email in JavaScript, with the use of regular expressions, string methods and external libraries. Each has its advantages and disadvantages depending on the type of application in which it is used.

Invalid emails can be caused by a number of reasons, from simple mistakes (typing in the wrong symbol) to significant life events like job changes or marriage that can cause an email address to change. It’s also common for email services to deactivate accounts after a certain amount of inactivity, making it necessary for companies to perform regular list cleaning.

In addition, the quality of your email list depends on the size of your subscriber base and how often you send. Generally, it’s best to perform list cleaning at least once a month. This ensures that you don’t overspend on expensive ESP or marketing platform fees by sending to inactive contacts, or waste your hard-earned marketing dollars by sending to addresses that are already marked as invalid.
