When my son was a child, every year on his birthday my spouse's elderly great aunt [who I had never met] sent my son a birthday card with three dollars. I always immediately wrote her back thanking her for the kind gift.

Do young people send thank you notes/emails... or is that courtesy now archaic ?

When I routinely send gifts to out-of-state relatives, I never even know if they were received [unless a check is cashed.]

If I send a gift via Amazon along with an email asking the person to let me know to verify it was received... I still don't get a response unless I send a follow-up email weeks later.

How would you handle this kind of situation ??
