Save your keystrokes... and save your trash. Keep it OUT of MY mailbox. Or else bring it over personally so we can get the matter settled once and for all.
And, no, it’s YOU who needs to be held accountable for what you attempt to put in MY mailbox. Why would I have to expend MY time and effort and money to keep away from me what YOU should not be sending me in the first place? Your SPAM does not have any place on MY property and I do NOT want to have to sort it and have it take up space in my trashcan. KEEP IT YOURSELF. (BTW, I never, ever patronize establishments that do direct spam-mail marketing. Nor will I.)
You’re insane....
OK. What's your address?
The spammers don't pay postage on those envelopes unless they get used.
I like to add a couple of steel washers to the ones I send back. Overweight letters get a penalty.
