Email validity software  is a tool that confirms an email address is valid and can receive messages. This type of technology is essential for digital marketers because it prevents them from sending emails to inactive or nonexistent customers and prospects. It also improves the deliverability of your campaigns and helps you avoid getting blacklisted by internet service providers (ISPs).

Most email validation tools do a simple syntax check to verify whether an email address is correctly formatted. For instance, they look for an @ symbol, a full stop, and a standardised suffix. However, this isn’t enough to guarantee that an email is valid. This is because the syntax check doesn’t verify that an address works or is linked to a live mailbox.

A more comprehensive approach involves pinging a mailbox to test its availability. Some email validation tools automatically ping all mailboxes on your list while others do it for specific addresses. The ping process is usually quick and takes less than a second. If a mailbox is active, the vendor will return a status code such as ‘Ok’ or ‘Doesn’t exist’.

The best email validation tools are easy to use and give you results that are clear and actionable. Most of them can be used to validate single emails or entire lists in just a few steps. In addition, they are often integrated with CRMs, email marketing and automation platforms, and landing page builders to enable you to verify data quickly and easily.
