Earlier this year we were invited to an Indian wedding in the U.S. by the parents of the bride whom we've known for 18-20 years though we rarely meet in person. Grand wedding in a huge sprawling open space venue. As is common now, the young couple had a creative website for the wedding. The invitation was in the form of getting a password by email to view the website. A few weeks before the wedding, the website was updated with information about gifts and dress code. There were two electronic ways to give "cash" or "money" gifts and gift registry in couple of online stores. They requested no gifts to be brought to the venue (understandable). We chose the money option and sent a decent amount 10 days before the wedding. I think DH used Venmo or a similar well-known online app. After that long background, here is the question: We did not receive any acknowledgement from the couple and it's been 7-8 months now. Other than seeing the amount gone in our bank records, nothing. What is the current etiquette to thank people who give gifts via online registry or money apps like Venmo, PayPal? Is it too much to expect a thank you email mentioning the amount/gift? The couple only updated their website with a general "Thank you all for attending. Here are some pictures." I don't mind the absence of a thank you. We gifted more as the woman's parents are old friends of ours. I am more curious about the thank you etiquette that people in their late 20's to mid 30's now follow. Thanking guests for wedding gifts by email (or text or phone) is optional? .
