The OP Group Count Datasource automatically will count the number of contacts in any group that has [VS] in the title and it will do that daily at the same time so that a trend of the changes can be seen over time.
Here are some example to Create in your Ontraport Account
1. A count of your marketing list (The contacts that you can email)
2. A count of the contacts who have been active in the last 90 days
3. A count of the number of new contacts signed up in the last 30 days that have not unsubscribed.
