Hi,
This features is very important when we speack with prospect. With this we can established the % of potential market prospected / How many converted etc…
By example :
we have a potential market of 50 000 accounts
We reach 35 000 on social media, convert 5000 with our newsletters (subscribers), 500 like SQLs, and 50 clients
We can considere that we got 10% of the potential market with our newsletter and the goal is 15% after the end of the year.
