Our email addresses and cell phone numbers have become highly valuable identifiers for marketers. Like government-issued IDs, your email address and phone number are directly associated with your identity and you will probably have them for life. This makes them ideal for tracking you across websites and accounts. It's no wonder that you are asked to provide this information all the time, for the simplest things. So why not throw them off your trail by having multiple email addresses and phone numbers? It's not as hard as you think, and it's getting easier all the time. This is a privacy concept called aliasing and we'll delve into all the details with the CEO and founder of SimpleLogin, Son Nguyen Kim.
