I've been typically using name+website@domain.tld to distinguish email origins (and leakage). Ironically, I've already set up otherdomain.tld@privacy.domain.tld to hide registrar information, but hadn't thought of using it for day-to-day signups until now.
I think I'll extend the latter (and reduce the required Spam score) before it gets sent to my inbox.
