What does 'my own average' in email performance exactly mean
The email performance graph shows dotted lines for 'my own average' but what numbers are these exactly? They dont appear to change for batch / automated so I conclude they are all over. But do they account for each individual email, or are they the average of each email average? And over which time period are they? Since they don't seem to change I'm guessing forever? I can't find any explanation about this.
