Invitation mistakes

I don't think that's too big of a deal. Perhaps they'll reach out to you if they didn't get the RSVP card

From experience, I wish we had numbered the RSVPs because we had 1 couple send theirs back without their name on it. We were able to figure out who it belonged to because they had put attending and changed it to not attending on the RSVP. My fiance had made a Facebook group and invited everyone on Facebook that was also invited to the wedding and his cousin originally put attending then changed it to unable to attend. As for forgetting the envelope, hopefully the person will just put it in an envelope themselves and mail it back. That is what we are having to do for a wedding we are attending. They sent us the invitation months and months ago and we miss placed the envelope with all our own planning so we are just sticking it in a regular envelope and stamping it ourselves.

Since there is only 1 person without an RSVP envelope, I think you are fine. We did number all the RSVP cards but everyone ended up filling them out so we didn't need to check.

I think you're totally fine. I wanted to number our RSVP cards, but had people helping me stuff the envelopes (my invites were DIY) and that didn't get done. Not the end of the world. I think most people will remember to write their names, its more a question of whether or not they are legible. But I wouldn't stress about it!

We didn’t number our rsvp cards and we were fine. We did have one moment of panic when we realized we had invited two couples with the last name fisher and they responded with “mr and mrs fisher” on their rsvp and we weren’t sure which one was which lol (one was coming, the other couldn’t make it). We got lucky though, and the ones who couldn’t make it also reached out to us personally to tell us they would be out of town and sent their well wishes.
