I want to do this too and here’s why:
I have over 100 sales reps and some of them are more tech savvy then others. In essence they are quite the competitors. AND, when a team leader can see EVERYONE’S emails being logged into Hubspot (which is basically all of the emails because our inboxes are plugged into HS), then some people feel like their prospects and leads are being “mined” by peeping eyes. (even if they “own” that lead on the system.
Further, when being part of the sales AND executive team, all of my emails are getting logged too, and I don’t always want my team leaders to see I’m in a meeting with the CEO or others when the auto-calendar invite emails come into my inbox.
