Opinions on sending out invites please!

I would do all online RSVPs or pay for postage. Another option is to do online RSVPs for everyone except elderly people or those who you know don't use technology, you could send them an RSVP card and pre-stamped envelope. I personally don't think your guests should have to pay to RSVP to your event. It's also going to make it more difficult to get RSVPs back.

Honestly, that's my plan. I'm going to include stamps for people who I really don't think will RSVP online, but I know all my friends will. A possible alternative is to only put actual RSVP cards in the invites for those you think will mail them back. The rest can have a card with the website url to RSVP online.

Either do all online RSVPs or all mail in. If all mail in then I would provide the stamp. We're going the online route.

We’re doing almost all online RSVPs. We’re only providing a pre-stamped RSVP card to our guests that don’t use computers. Everyone else will get a details / RSVP card directing them to our website.

It would be very rude to send RSVPs to people without a stamp unless their only option is to RSVP online. If you want people to mail RVSPs in then you need to stamp them.

Actually, etiquette has never considered a stamp necessary for a RSVP, or an envelope. An adult is presumed capable of getting those things himself.
People do it , treating people like infants who would never manage to return the RSVP without help. In fact, if someone actually wants to go, they will manage to get a stamp. So offer both ways to reply, and don't waste stamps. I always found it amazing that people assumed I could travel 9,000 miles alone, on extended vacation, yet worried that even if I really wanted to attend their wedding, not having a stamp would be my downfall. Treat your invited guests like adults. Assume that they have the will and skills to get a stamp all by themselves. Let's face it, even with a stamped addressed envelope, lots of people are simply too rude to be bothered, and don't reply. Not putting a stamp on your RSVP envelope is just fine.

Personally, I would include postage. It will be respectful as well as potentially help you get more RSVP replies in a timely manner!

This is a "know your crowd" kind of thing. Your idea would NOT work for me at all, seeing as about 80% of my guests are older people, some of them don't even own a computer.

But if your crowd is younger, more tech savvy, then go for it. If you feel that most of your guests would use the online RSVP option with no problem, then do that. But if you have any elderly guests, you might include the card with postage for those people.

We gave guests the option to RSVP via mail or online. We provided stamps for the return envelopes and honestly way more people used those than the online option.

In all my decades of attending weddings (I'm well over 50), I have never received a wedding invitation without a stamped and addressed RSVP card/envelope. It's not treating your guests as infants who can't figure out how to respond, it's done for the convenience of your guests. Put the stamp on there and don't worry about it. People WILL notice if you don't and frankly it looks cheap not to do so.

Yikes y’all...this just made me more conflicted lol

View Quoted Comment In my experience, older people who still write letters, and do not pay bills online, are those most likely to have stamps and envelopes around the house.

View Quoted Comment About 1/4 of the weddings we are invited to have prestamped RSVP cards/ envelopes, the rest no. Only 37, but as hubby and I come from big families, from completely different areas and ethnic groups, he urban, me rural, and we attend 2-17 weddings a year. And cannot attend many more. I have never seen one prestamped from any other country. We regularly receive other invitations, to formal business affairs, and assorted other graduations, anniversary parties, Christenings, you name it. Rarely with reply envelopes or stamps. And still we always, always reply. But check an etiquette, social manners or protocol book. They have never been required for any kind of invitation, including formal balls, white or black tie affairs, or weddings. Or even check Miss Manners or Emily Post online.

Pay for stamps for all AND offer an online option. Your fiance's parents are correct on this one. Save your money someplace else.
