If you make use of it, you will ensure minimized bounce rates, easy-to-identify unresponsive emails, communicate confidently, and avoid fake signups.

Now, it’s important to know more about email verification and its approaches.

Validating the Email Syntax

The initial approach of email verification is to check the validity of the email address. In this, it examines both the local part and the domain part of that address. These two parts are divided in the mail address by @ symbol.

Some of the constraints used to validate the syntax are,

  • In the local part, some of the special characters i.e., #%’+/? _.| ~ ! $ & * - = ^`{} are allowed without any restrictions. But the other special characters are allowed to be mentioned within quotes and preceded with a backslash symbol. However, the period sign (dot symbol) is restricted to use at the initial or end of a local part and is not allowed to be used in a continuous sequence.
  • The Internet corporation restricts dotless domain names because of some security reasons. When the hyphen symbol is mentioned at the initial or final, then it will be an invalid address.

Ensuring the Mail Address's Existence

After successfully completing the syntax validation, the SMTP connection will be utilized for checking the validated email addresses. In this, the existence of the validated email address is verified using the SMTP server. When the evaluated output is in negative status like User unknown, then that email address will not be an existent email. If the given response is ok, the specified email address will be a valid one.
