I have >10 apps for external clients currently in the App Store that are exactly like Hey (not email clients though), focussed on business+consumer clients, with a login and you have to order outside the store to be able to login. We even reference to that in some of the apps. You can't do anything in the app until you pay for a subscription on the repspective site. The most recent one got approved 2 months ago, and some apps are >2 years old and have received regular updates.
The difference may be that they do not have the revenue Basecamp has.
In the past when an app got refused, we resubmitted without changes and got approved. It's a shitshow.
