Are you still using open and click rates to measure the performance of your email campaigns?
There’s a better and more accurate way -- which is to measure by earnings. How do you plan to implement this?
I use BirdSend, which tracks email earnings out of the box. Whether it’s tracking earnings for my entire account, or based on a specific ad campaign (tag), or a specific email series, or a specific broadcast/newsletter -- I know my numbers the moment I login to my account.
