Welcome to the forum and thanks for the request.
Can you tell us a little bit more, why do you need a mail notification for this two tasks?
What is your goal with the notification mail?
We are using Veeam since some months now and are evaluating the tape features.
The goal of the mail notification is to get informed actively, when longer running tasks like tape inventory / catalogue are finished, and not to have to look at the Veeam console.
And for "documentation" when which tape was (re)used.
