I will address one aspect at a time.
1. User feedback.
Any user who is accountable for multiple products and doesn’t find this useful, doesn’t understand marketing. From the response here it appears that Hubspot doesn’t either. This feature could be used by all users except those marketing only one product.
2. Usage data.
Usage was very low. Probably because the data is meaningless as it is presented. If Hubspot provided meaningful data about prospects and communicated how the data could help marketing usage would soar.
3. Recent regulations. The GDPR was enforced in the EU starting last week. Under the GDPR, storing IP addresses requires consent. The removed feature didn’t play nicely with that requirement. THEN FIX IT.
