3. Ping the Server

Another procedure to verify the email address is to ping the mail server to check if the email address is valid or not.

This process is quite risky and also slow but it gives accurate result.

Here are some steps to verify email addresses by ping mail server

  1. First enable a Telnet on Window or PuTTY or Netcat on MacOS. (How sto enable Telnet on Window)
  2. Find the Mail Server – open command prompt (cmd) and type nslookup –type=mx In this case replace with your domain name. Press enter button, and then it will load all the list of MX Record for that domain.
  1. Connect To the server – As you see multiple MX records for a particular domain, with several preference levels. Pick one of them and send out a pretend email to the server. Using Telent, we write a following command.

telnet 25

  1. After that now talk to the server, write Hello then press enter, mail from: (replace email address from yours) press enter and type the recipient email address we want to validate.


mail from: <>

rcpt to: <>

Here, you will get the result if email address is valid:

220 ESMTP h3si7768221lfu.32 – gsmtp

250 at your service
mail from:<>
250 2.1.0 OK h3si7768221lfu.32 – gsmtp
rcpt to:<>
250 2.1.5 OK h3si7768221lfu.32 – gsmtp
221 2.0.0 closing connection h3si7768221lfu.32 – gsmtp

If email address is not valid

220 ESMTP h3si7768221lfu.32 – gsmtp

250 at your service
mail from:<>
250 2.1.0 OK h3si7768221lfu.32 – gsmtp
rcpt to:<>
550-5.1.1 The email account that you tried to reach does not exist. Please try

550-5.1.1 double-checking the recipient’s email address for typos or

221 2.0.0 closing connection l26si4867318ljg.18 – gsmtp

4.Check Bulk Email Verify Email Address

Instead of checking one email at a time, you can verify bulk email addresses using the free bulk email verification tool. You can verify 25 email at a time but when you need to verify 100 or 2000 email at a time, purchase a premium plan of that free tool.

The free tool I told you above only verifies one email at a time. But if you have 1000 email list in your list then this free tool is not so effective so you need bulk email verification tool.
