Or you could go full nutcase like somebody...(whom I always see when I look in the mirror)
Hey! I also do this!
Just a tip, you can pay great alternative email services like Protonmail[1] and Tutanota[2] like $1-$5 a month(depending on what service), and get multiple aliases to your emails. So you simply don't need to switch emails every time you want to check messages from other emails.
But yea you can just simply create multiple Gmail accounts for free if privacy isn't an issue for you.
