In a follow-up here, this method has updated slightly with some HubSpot updates since this solution in 2022. Instead of a calculation property, count is now an option under the Rollup field type.
So a slight adjustment here:
- Go to your custom and hit the button “create property”
- Instead of calculation as the field type, select “Rollup” as the field type
- Then select “Count” as the Rollup type
- Choose Number format (I prefer Unformatted)
- Choose the associated record type of “Contact”
- Choose association labels (likely default to “All association labels” if you have a singular, standard association setting fo the custom object
- Choose the associated record property of “Create Date”
- (optional to add contisional settings but not required.
- Click save
Screenshot attached to this update and hope this helps!
Thanks!
