USERTRACK code should be placed at the beginning of mail, not at the end. E.g. Gmail truncates too long e-mails and shows "View entire message". So opening of such e-mail is not tracked.
Yes, good point. In fact, we could put two trackers in, one at the top and one at the bottom. Would be interesting to see the differences.
Presumably adding a second set of tracking would result in two sets of stats for each message which would need to be summed for display on admin pages?
Assigning the first part of this task to xheni to move the tracking to the top instead of the bottom of messages.
The other thing to change about tracking is to make it a bigger image, eg to use any image in the campaign for tracking. But that's a new feature as well.
