I think most answers here are the exact reason why I don't want to read the same pointless "daily found" logs 10 times for a series of traditionals: The entitlement of the users.
When logs weren't just "spam", like in the early days, I gladly read them. Now it is rare having a log that even has anything to do with the cache (instead telling some story about the cacher which i couldnt care less about). Having an option to only get emails for NM seems like the most obvious, proper solution.
