Cut down notifications from Nagios


I am currently monitoring about 40 hosts using NsClient. Each host has between 5-8 services running on each of them. I was trying to find a way to get less notifications because I’m currently getting about 200 a week. Is there anyway for if one service goes down on a host to make nagios do a check of all the services and just send one email saying which ones are down rather than sending 6 separate emails if there is a blip in internet connection. If anyone knows how to do this or has any other ideas on how to cut down the amount of emails but make sure I don’t miss anything it would be really useful.
Thank you very much,
