BlueData

I'm very happy with this app and the customer support. They help me collecting the GCLID from google so it can be sent to Hubspot. Customer support, Haley and the devs of the app where very fast and interested to solve all the issues that I had. Adapting the app to my requirements (where possible). 100% recommended.

Very good app, and the customer service is great. I tried several apps and this is the best free applications, and several add ons to use.
