No, I have it set up so I get one notice from Hubpages which includes notices about the comments on Hubs and Questions I follow.
I rarely get unwanted mail.
You can change how you receive notices in your "My Account" settings. Choose "Profile" and then, in the box on the left, choose "E-mail Settings".
There you can choose to get instant mail when different things are done. You can also choose to include it in a single digest notification or not at all.
It makes it easier to keep your in-box clear of unwanted clutter and gives you a little more control over your Hubpages experience.
