  track users' full email domain
  **Describe the feature you'd like and what it will do**
  In HS v2.5.4, we don't track full user email domain in our metrics.
  
  
  **Why is this feature important?**
  We need more insight into how HS' ecosystem of tools are being used. This information should drive our continued development on existing tools and our consideration of additions for future use.
