Great point. Thanks for forwarding. One thing that I've done for years to let the marketers know how I feel is to mail them back their own junk, at their cost.
Often times physical junk mail comes with postage paid self addressed return envelopes. You can stuff all your own junk mail in their return envelope and mail it back to them. Heck, send them extra mail too.
The companies don't have to pay for these envelopes until you mail them back. They are all billed to a corporate account. They don't care since most of the time when the letters come back it's to do business with them. But if we all mailed their garbage back to them at their cost, they may stop sending it to us.
I wrote a detailed post about this a while ago. If anyone is interested you can read what I do in detail with photos here:
