I have Gmail accounts that correspond to my Blogger accounts. And I recently noticed something strange. Today I received a number of e-mails from Ad Engage. But when I went back to check some of the details, it seemed like there was only one e-mail on my Gmail page.Then I figured the number in parentheses next to the sender must have had something to do with it. It turns out that Gmail automatically bunches e-mails in the "same conversation" together on one line. You have to open the e-mail and choose the stacking tabs to see each separate e-mail message.
I searched all over the Gmail settings, but could not find a way to turn this feature off. It was very annoying. This is not intuitive in my opinion. Judging from the number of questions posted to Google Groups about this very feature, I guess a lot of other people share my opinion.
If you use Gmail, be aware that messages from the same sender can "stack" in your Inbox.
