Using email as a notification service works in this case. The user probably gets a notification for new emails.. at least if they do they chose to. :)
Even when the email does reach the end user, most people get so many emails it’s easy to get lost in the noise.
If your e-mail is important, people will find it.
If your e-mail gets lost in the noise, then notification is probably not essential.
I have no interest in the former.
