I have 2 email accounts. My preferred account I only give to my family and close friends for really important things. My church and doctors also have this email. That account stays fairly "clean" from junk emails.
My second account is for all the "junk" emails. I use this address for online purchases. I used to get about 25 junk emails a month, but something has really changed recently. I am getting about 200 junk emails every few days now!
They are from all kinds of businesses. Everything from shopping, credit, congratulations you have won something, your package is waiting, etc. I used to unsubscribe to these emails, but I don't even want to open these for fear they'll get more info on me. I just do a mass delete.
