EVERYBODY should do this, when you receive a letter for a credit card application, or a loan etc. or any junk letter with a pre-paid envelope to reply with, fill it full of ripped up paper or old take-away menus or anything you have to hand and send it back to them. I know its very sad, but it does'nt half make you feel good.
If you do what alan says then it will become so expensive they will stop sending it altogether. Saving tons of wasteage.
Another thing I do is put a label over the address and write:
"Not known at his address, sender: please remove from your records, PO: RTS" that way you don't even have to open them and the sender pays for postage, again if we all did it, junk mail would die.
I'm registered with the MPS and still get all those letters offering me credit cards! So it doesn't eliminate them all, not sure which it does eliminate!
We ' ve been getting so much junk mail and circulars ,we get more rubbish thru our letterbox than we do proper post. About 6 weeks ago I started crossing our name of the letterheading , and wrote return to sender followed by the return address; which is always printed somewhere on the envelope then popped them back in the postbox.. This week I have slowly noticed a drop in the amount of c**p that has come thru the letterbox; now this might be coincidence but as Alan2 says , it makes you feel good !!
The problem with doing that Scotty is your postman might see what you've written and assume that you've moved and send back all your mail,including the good stuff!
We've signed up for the mailing preference service but still occasionally get such junk and on occasions I've done just as you have, except that I usually include somebody else's junk mail (having first removed my identifying address). However, if you have any Avery labels you can always print out a sheet of them which you can stick on such envelopes saying "Return to sender. Please remove me from your mailing list". It saves the problem of having to write on the envelope every time before returning it to the post box.
