Tomorrow is, what I like to call, national unsubscribe from emails day.
I used to say yes to every store, company, or retailer email I could get. I loved the coupons, sale alerts, and new product updates.
Five or so years ago, I was done with it all. Cyber Monday was the last straw. One company sent me over ten messages in a single day. The amount of email I had to wade through to get to what I wanted to read was too much.
From that point on, I hit unsubscribe on all commercial emails. It's just too easy to find discount codes online these days (thank you, Honey *referral link*).
Occasionally, I either get added back on to lists or an old company randomly emails me. They always appear on Black Friday and Cyber Monday. I am ready to click unsubscribe on every single message. (You can also search "unsubscribe" and find mailing lists that way.)
The side benefit of all this - I spend a lot less money.
