How we calculate this

First we count how many customers match the email.
Then we remove people we are not allowed to email.
Then we hold back a small test group who do not receive the email.
Then we estimate how many people open, click, and buy or take the action.
The most important number is the extra result compared with people who were not emailed.
This helps avoid counting sales that would have happened anyway.
