Not air tight, not truly “OpSec,” but people do call me crazy for having a separate e-mail for every service. This has caught three leaks so far–if you receive spam you immediately know which service got pwned. If that happens I delete the e-mail and move on. Takes some effort, but is worth it in my opinion.
