🚀 How Does Email Address Verification Work?

An Email Validation tool uses an easy-to-use and sophisticated email verification system to check for syntax regularity. However, a standard email verification system goes above JavaScript. It uses AI and multi-layer testing to identify troublesome email addresses in real time.

Many email verification tools use data to predict the likelihood of an email being a hard bounce. Each email that runs through this system is categorized using a scoring system and 30 different diagnostic codes.

💻 What happens if you need to spend more emails than your monthly allotment?

Some email verification tools are priced on a pay-as-you-go model with payment at the end of the month, depending on how many emails were sent.

  • Check for spam Trap
  • Disposable Email Address Check
  • Role-based Account Check
