Recycle your junk mail.
We all agree that junk mail is the worst. But do you know just how bad it is? Every year, 100 million trees, 28 billion gallons of water, and $320 million in local tax money are used for the production and disposal of junk mail. Remove yourself from bulk-mailing lists by using our handy form letters, and watch your mailbox slowly begin to shrink. In the mean time, why not make the best of a bad situation? Use the reply envelopes for your own use. Cover the pre-inked address with a white business label and you’re in business! These free envelopes mean less envelopes we’re buying and it feels kinda good to stick it to snail-mail spammers.
