Best Invalid Email Checker ever

Hi

Hope you all have a very good weekend! I am a newbie. I need a help from you guys. I have over 2500 subscribers at my website. I suspect that majority of them signed up with the invalid emails. Now, I want to identify the Invalid emails and remove them forever. Is there any email checker that can help me very well? I will be waiting for your kind help guys!

Thanks in advance.

Good Luck!

There is no such thing as the perfect email validator. The following has served me well though:

Code:

---

<?php
$test='abc@domain.info';
if(preg_match('/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/i',
        $test)) {echo "YES";}
else {echo "NO";}
?>

Is the subscription to your site based on a program you wrote or a third party program like phpbb or wordpress?

Oh, there's no specific email checker. The best thing you can do, you can open an individual email for your website and use it for only your website purpose. It will help you lot. :)
