> 75%+ of all emails I receive on my non-work address to not be worth looking at.
If you use any of the major mail providers (gmail, hotmail, yahoo), you should not see 75% spam in your inbox. It's worth noting that email that's "not worth looking at" is not necessarily the same as spam. The group you mentioned includes both real spam (phishing, pills, etc) and gray mail (newsletter, notifications, etc). If most of your inbox is gray mail that you're not interested in maybe it's worth setting up some filter rules or consider unsubscribing to those mailing lists.
Gray mail is generally a difficult problem for spam filters to solve since a critical email to one person might be junk to another. There are evolving ways to improve this filter but it usually requires action on the user, such as clicking the junk button or deleting them without reading.
