Other Change the sound of notifications?

I have a friend that really need to hear when email arrives. We can’t find any way to alter the volume of this.
Ie, when a mail arrives, we want the highest possible volume. Nothing else, just emails.
Is this possible? 🤔

It has always been a complaint of mine that there is a lack of more different sounds available.
