Once you get the address I would send it via fedex or another Carrier other than USPS as they would throw away Any correspondence
I agree about the USPS.
I sent my sister a letter with a few irreplaceable pictures, of her playing with my son when he was about 18 months old, of her two sons, one of whom died of cancer at the age of nine.
About a month later, I received a clear plastic bag with the note, “Because We Care,” on it. Inside was a ripped up letter and envelope...but no pictures.
WTF, I said to my husband. Then he pointed out the “we care” thing and we both cracked up.
Definitely don’t use the USPS for anything you “care” about. ;)
