Return address / Undelivered
I am a prospective customer in France, and I have a question about the return address :
1) Is this a standard one from Postal Methods, or can I include my own address in France ?
2) Does Postal Methods manage undelivered mail ? (= mail come back when address is not sufficient, not valid, moved, ...)
3) Is it possible to insert NO return address, but a commercial message which appear on the top window of the envelope.
4) Do you offer an envelope with no return address window ?
