A process integrated within a popular form builder plugin, it ensures the accuracy and validity of email addresses submitted through web forms. This function verifies that the format adheres to standard email syntax (e.g., `username@domain.com`) and can optionally confirm the existence of the domain. As an example, when a user enters an incorrectly formatted address, such as omitting the “@” symbol or using an invalid domain, the system flags the error and prompts the user to correct their input before form submission.
The implementation of this validation mechanism offers several advantages. It significantly reduces the rate of bounced emails, leading to more reliable communication and improved sender reputation. Moreover, it minimizes the collection of inaccurate data, thereby enhancing the quality of leads and reducing wasted resources on contacting invalid addresses. Historically, the need for such verification arose from the increasing problem of spam and incorrect form submissions, prompting the development of automated checks to maintain data integrity.
