Emails accounts... and verification of accounts.
As I understand you can buy emails to include them in your GSA runs.
I suppose you use 1 email per run of 1 tier... Is that correct?
A website like facebook for example, won't let you open a second account with the same email, so if you are opening new accounts in the same website, then you might need a different email..... and that is why you need a lot of emails depending on what you are doing.... is that correct?
Now... once you have the submission of email to a website.... Does the system goes back into your email and click the link for account verification?
