Send me an email when blocked sites is higher than normal.
Lets say average blocked sites is 5-10 a day or a week. Then all of the sudden blocked sites goes to 100 a day. Can OpenDNS send 1 info email ( if feature is enabled) saying higher than normal blocked sites thru Open DNS today.

OpenDNS does not block sites, it only blocks domains either because of category or because they were specifically blacklisted. Owing to the fact that DNS lookups can be cached on the local machine or somewhere else in the local network, and the way that websites are built there is no direct relationship between websites that were visited, or even the exact internet activity that is going on with your connection. Depending on how a web page is created and the categories that you have blocked a single webpage could easily result in a dozen or more blocked domains simply by going to a single page.
A simple accounting of blocked domains is pretty much useless for figuring out if you have a problem or not because there is not a one to one correlation with websites or pages visited.
Aside from OpenDNS and DNS in general work, how is "normal" supposed to be defined? Is it based on sheer number of blocked domains, numbers of domains from a specific category that is blocked, or some other metric, or something else. Would this metric be for all users, or would it somehow be customizable for each user?
Is this amount of coding and processing something that you want added to the free service? The various pay services that I'm familiar with are already capable of sending a daily report, or summary, that includes various statistics for the preceding day.

I believe that the easy way to configure this is to allow each account to set a threshold of blocked domains...so for example, 10 blocks in 1 hour. The other option, which would require more backend coding, would be to allow for baselining of each account's data and if it exceeds the baseline by a certain percentage, then alert.

I agree...this is a simple thing to setup. They already know how many blocked domains have been hit for a time frame. Its a pain to login all the time to check things. Let us set a threshold and when that threshold is hit it sends an email just like this IdeaBank sends emails. Easy Peasy. Makes sense to me.
