Reports Questions

Hi,

What’s the difference between: Email Clicks and Email Opens?

What’s the actual meaning of Page View?

Also it’s noticed that when a Dubb email campaign (Dubb Sender) gets send and the campaing includes in the play list a number of different videos, the initial Dubb Sender campaign does not give reporting on the playlist videos, it gives reporting only on the actual campaign video.
Thus, how can we tell from which Dubb Sender campaign each playlist video was seen from?

Thanks.

Guys? Anyone there?
Tnks.
