I can't define what your company sees as risk for you.
I assume you access your email over HTTPS, so that comes with a certain amount of security built in, but the fact this information is available externally from the company means it is still hackable.
You need to sit with your company and define what you consider risk. Look at the content of the types of notification messages and decide what information in them represents a risk. This is not something I can do. It is up to you and representatives of your company to define risk.
