When adding a campaign, I see a field for entering the number of bounced emails. What do I type there? I don’t know how many bounced emails I will have.

When you add the campaign, leave the “Number of Bounced” field empty. After you process bounced emails either using G-Lock EasyMail7 Bounce Handler or a different bounce handler tool, open the campaign in your account and enter the number of bounced emails. G-Lock Analytics will reset email tracking statistics with regards to the number of bounced emails and you will get more accurate results.
