How to check the validity of email address?

1. Syntax check

Email verification tool starts the process of checking with the marking addresses that don’t comply with standard spelling rules. Emails that do not meet the standards are excluded from the list. For example, addresses like ann#gmail.com, john!@$yahoo.com.

As a result – your mailing lists will be cleaned from address with typos or those that were intentionally misspelled.

2. Verification of the email addresses domain

The existence of a domain is the key to the relevance of the email address. Addresses with invalid domains are not allowed to the third stage of verification.

If the recipient’s address is syntactically correct and the domain exists, then it makes sense to check for a specific address in the domain.

3. The analysis of email server response

The program tries to send a message to the server and then processes its response. Therefore, with great accuracy, you can determine the validity of an email address from the mail server responses.

As a result of this three-step bulk email verification, Email Verifier helps you not only to filter out the maximum number of non-existent email addresses but also to prevent the removal of the real ones.
