I was a mailman for 30 years and am now retired. I know from personal experience that a letter mailed without a stamp will be returned to sender if the return address is shown.

I forgot to put the sticker on my letter before i drop in the mail box? And there is no return address do they return to the post office i hope it will be there i will go back to put the sticker pls..help my question..

The letter will be returned to you for postage due. Hopefully, you had your return address on it. If not, it will go to the "dead letter" office and be destroyed.

The mailman may not even take it if it has no postage (if he notices), or if you have the return address on your envelope it should just be sent back to you!

SFC is correct. It will come back. Years ago it would have gone to it's destination and delivered postage due.

It will come back to you stamped "insufficient postage"

As long as you put a return address on it, then you will get it back! No worries.
