Email Address Verification API

Introduction

Email is one of the most underrated customer engagement channels. Many email marketers, sales professionals and customer care team struggle with the quality of their customer email ids. As a result, businesses are losing sales and marketing opportunities. 

One of the common reasons is the poor email validation check during account signup or lead generation stage. Many form validation methods only check the syntax of the email address. But, the email verification requires more than syntax check. 

Our Email Verification API designed to render fast and straightforward email verification check. The API provides the following validation:

  • Full standard compliance syntax check
  • Full domain part check including mail servers configuration check
  • Checking against knowing abusive email domains and accounts list
  • Check if the email address is disposable or not

You can learn more about our process and get a deeper understanding of email verification methods in our blog post.
