[company name]@[my domain] has been my anti-spam for decades. Just register your own domain name, and create a catch-all email account. Then give out tagged emails to every company. Once in a while I get some idiot who thinks I'm their boss or a scammer because of the email. Imagine getting a call to customer service transferred to AT&T security because they don't like ATT@[my domain].
