Definitely need the ability to suppress this if it becomes a feature. During cleanups especially I might have 100 transactions that I need info on and I routinely warn my clients to not freak out when they log in and see the volume.

I can think this could be really useful as long as you have the option to suppress it on an email by email basis. Most of my clients get a few questions at a time, but I have one big account where I may need to submit thirty questions and it happens frequently due to the nature of their business.
