Segment is not an authorized subprocessor
For organizations based in the EU (or processing EU data) and concerned with GDPR compliance, please note that Segment is not an authorized subprocessor under our Data Processing Agreement. We encourage all organizations to independently verify the security of every third-party processor.
One of tools that is available through Segment (segment.com) is fullstory (https://www.fullstory.com/). Full story records user activities so that you can see exactly what your supporters are doing while they're on your site.
After integrating, you'll be given a dashboard from which you can view recordings of user activity.
While it's admittedly a bit creepy, we think that fullstory may be helpful to get a sense of the full user journey for your supporters. Are they having trouble finding something on the site? Are they getting stuck on one page? When people are brought to a petition from a blast email, do they sign the petition and leave or are they clicking around the site?
Another provider of this type of service is Mouseflow.
