When looking at the totals of an email performance report (when more than one email is listed), are the percentages a weighted average – which give greater weight to those emails with larger distribution lists? In otherwords if there were two emails:
Email 1: 10,000 delivered | 10% open rate
Email 2: 100 delivered | 50% open rate
Would the total open rate % be 30% (unweighted) or 10.5% (weighted)?
