Mixpanel without Mixpanel

Expected Behaviour:

I'd like to prevent websites and mobile apps on my network from "phoning home" to Mixpanel to report their analytics, while allowing me to access our company's dashboards on Mixpanel from my laptop.

Actual Behaviour:

When Pi Hole blocks Mixpanel (as it does out-of-the-box), I can't access https://mixpanel.com from a browser.

Is there anything I can whitelist to allow me to log in to my mixpanel.com and see our analytics dashboard, while still preventing other people's apps and websites sending data to Mixpanel?
