FI and his parents have a somewhat strained relationship. They are not attending the wedding, however, they claim they are "supportive." FMIL just sent a set of VERY nice pots, pans, utensils, etc. to my parents' house as a wedding gift. She emailed FI to let him know that the gifts were coming and seemed very concerned about them arriving. My shower is this Saturday so I'm going to unwrap them then.
My question is, should FI shoot her an email back to let her know they arrived? Obviously I'm going to send a formal thank you card, but would it be inappropriate to let her know that we received them via email, or would it be better to just wait and send the thank you? I may be thinking into this too much but I was unsure so I thought you ladies might have some input.
