1)At first You Must have Just 1 Gmail Account

2)Then go to the site https://thebot.net/api/gmail/ and put that account name here (without @gmail.com)

3)Just press "Generate" and you will get Thousands of FREE ACCOUNTS.

4)They are all Connected with your first account so YOU JUST USE THE NORMAL MAIL INBOX FOR ALL THE ACCOUNTS!!!

So if I send a mail to any of these accounts you just check it on the inbox of the first account.
If you wanna acces to youtube, drive,ecc just use the first (the original) accounts
