You can take this to an extreme (like I do) and use a different email address for every party with whom you communicate. It makes it rather obvious who leaked your email address, and also easy to shut them out (looking at you ActBlue!). It also leads to some amusing personal interactions. I once rebooked a cancelled flight on JetBlue at the ticket counter. When the agent saw my email she said “wow, you must really like JetBlue.” I just nodded but I was laughing inside because it’s definitely the opposite!
