Email Address Validator

This is an email address existence confirmation checker that provides email address existence confirmation. Does the email address still exist? Existence can be easily confirmed and checked.

How to use

1) Paste the list of email addresses you want to check for existence.
2) Click the "Confirm" button.
3) "OK" is displayed for those that exist, "NG" is displayed for those that do not exist.

Notes

Confirming the existence of an email address is not 100% certain. Even if it is ``NG'', it just means ``there is a high possibility that it does not exist.'' note that.
This tool is available for free.
