If anyone can help me on this, I would really appreciate it, especially since I've gotten so much help already just reading other people's posts. I committed a faux-pas already by emailing a few people the date, without realizing that we wouldn't be able to invite them to the wedding once we sat down and did the numbers. I didn't send them an invitation to the shower or the ceremony, and we only see each other about once a year or so. Two days ago, one of them emailed all of us saying that they'd see us at my wedding as soon as I told them the place and time. What's the best way to do this? I don't even have phone numbers, just emails, and I know there's an apology in order but have no idea whether to email all of them, or just the one person. Any advice will help.
