Gmail account signup guidelines
1. Create only 1 or 2 accounts per IP then refresh your IP by disconnecting/reconnecting your internet connection.
You can set Renew IP to automatically disconnect/reconnect after every 2 or 3 accounts.
2. If you are using proxies then we recommend to use private proxies instead of free proxies. Most of the free proxies are already exhausted and banned by Gmail. And create only 2 or 3 accounts per proxy.
3. Create a pause of 30 seconds or more between each accounts. It can be set by setting desired number of seconds in field '
Wait (in sec) before starting new thread'
4. Change your IP address if you get 3-4 consecutive signup failure. For this purpose
we added a new feature to Renew IP, it will allow you to obtain a new IP in case of consecutive signup failure.
