Email performance report totals: weighted or unweighted?

[Dan_Stevens_]

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)?

Hi Dan, 

good question. The total open rate is weighted, so it would be 10.5%. 

Good luck!
