The famous verify and validate emails with PHP code out” holds true when it comes to email addresses. When your digital marketing campaigns are based on invalid or stale addresses, you’ll be missing out on leads and revenue opportunities.

The good news is, there are many ways to validate email addresses with PHP. One popular way is to use regular expressions, a flexible pattern-matching technique that allows you to omit illegal characters such as “_”, “-“, and “.” from an email address. The problem with this approach is that it’s limited to syntax validation.

Another option is to integrate a simple email validation API into your website backend. This will reduce the load on your local server, and will also allow you to perform more sophisticated checks on the email address beyond its format. For instance, you can check for if the domain name is valid by performing an MX lookup or determine whether it’s a disposable email address by checking its profile information.

The most advanced way to validate email addresses is to use a multi-faceted strategy that combines the best of both worlds: automation and human-based checks. For example, you can use Kickbox’s email validation API to identify all incoming emails as safe for sending, valid but risky, or invalid and remove them from your databases at the point-of-capture.
