Proper Notifications documentation

Hi,

i'm having trouble with setting up the email notifications. What should i set and not set to have the users not to be overwhelmed by notifications in their mailbox.

Enabling "Notify admin on new entries" the administrators get several mails when there is a new post. Guess they should receive just one mail.

I have searched for proper documentation to set this the way i works the best. But can't find anything.

Any help is welcome.

kind regads,
Mark
