If they’re US postage stamps and you don’t have anything bulky in there, you’re perfectly fine! Otherwise it’ll get sent back if there’s not enough postage or wrong address

if they already have stamps on them u can just drop them off at the post office, many have drop boxes where u can put envelopes in without needing to like speak to someone or wait in a line

Yeah if your post office has a drop box you can just toss them in there, or any of the blue post boxes that you see outside. If not, just bring them to the counter and let them know you’re dropping them off to mail out!

You might need to pay shipping but I think you already paid for that with the stamp right? Can’t u just put em all in ur mailbox?
