Receive email notifications daily and not with every activity

Hello,

Is there a way to change frequency for email notifications from comments in a prototype?

By now, every time someone adds a comment in a prototype, the person who added it and I receive an email notification. It generates lots of annoying notifications for me and for my clients.

The only alternative I found was to set the notifications to none in the Notification Center. Is there other way to change its frequency?

Thank you,
