I don't know why they bother.
If I got my mail every other day I would be fine. Fewer trips to the garbage can that way.
I horde it up and use it as a free weed block layer in the garden beds under the mulch.
A few years ago I collected a years worth of junk mail I had received over a years period, it totaled just over 135 lbs. Understand this was with the ex wife who I think was on every mailing list in the US.
for those of us that heat with a wood stove. Fire Starter.
Don't do that, play a little game with them. They don't get charged for that return postage until it is used. I return other junk mail in their return envelopes. For example, I will return a Visa application in the mortgage brokers return envelope.
I wish environmentalists would shut them down; it is a waste, and if you’re away it just advertises that when the junk is all over the porch/spilling from the mailbox...
My wife gets flooded with useless junk mail and catalogs. I get virtually no mail unless it’s a bill or a package.
All of that gets junked as soon as possible.
