Re: "We sent out an information message"
Most of the junk mail I get is un-addressed which apparently gets around my MPS registration. It is almost all delivered by the postman doing normal deliveries - indeed much of it proudly displays a 'delivered by Royal Mail' logo.
I simply take it with me in the morning and put it into a Royal Mail post box for them to recycle.
I am hoping, perhaps naively, that if enough of us do this it will become uneconomical for Royal Mail and we'd save a lot of resources.
