Sorry if this has been asked before I looked but didn't see a related post.
In the past two months I've sent 2 gifts (one for a wedding of a coworker in early July, one for a new baby in early August). I have not received thank you cards for either. Is there a nice way to ask if the receipients received the packages?
Both were sent through the US Postal Service so I don't have a way to track them.
