Is it possible to get the stats on how many emails are created per team member in the service hub? Even better if this can be broken down on a per day/per week/per month basis.
There is a report in the report library which you could use. Navigate to Menu > Reports > Reports > Reportlibrary > Search for "Activity leaderboard by rep with type breakdown". The description states that this is for sales but you can click Edit in builder and further customize this report and filter it for customer service.
Click Filters and add one for either HubSpot Team (is any of customer service team) or Activity assigned to (is any of the service team users).
If you only want to see emails in this report, you could further filter by Activity type.
Hope this helps!
