Can I mail my direct sales catalogs, like you’d receive a magazine(without packaging), to my neighbors?

I have some extras, 25 to be exact, from this season and I dont want to bother ppl going door to door and I live in a rural area so mail makes more sense. Can I just stamp and address them n stick em in my mailbox?

Yes, if you have the correct postage on the addressed literature, you can put them in your mail box, flip up the flag, and your postman will take and deliver the material. I love the post office!!!!
