For Wicked Reports to work, you need to have a source for your Order data and a source for your Contact data.  If you use Drip (https://www.drip.co/) to store you contacts and for your marketing automation AND process orders through Stripe or use the Wicked Reports Order API, you can integrate Drip with Wicked Reports.

** Again, you will authorize Drip if you also process orders through Stripe or use the Wicked Reports Order API **
