Not much of a secret, but clicking the unsubscribe links in emails helps. Anything new I sign up to I'm pretty religious about it. Some new email I didn't ask for -> instant unsubscribe. Works way better than one might expect.
Very noticeable when using custom domain and emails where I might sign up to the same service several times.
