How did you handle wedding RSVPs for families?

I’m curious how people actually handled RSVPs when guests came as families or couples.

If you’ve planned a wedding, did you track households together or everyone individually? Did one person usually respond for the group, or did you end up chasing people separately?

I’ve seen everything from spreadsheets to wedding websites to text messages, and none of it seems perfect. I’m wondering what worked best for you and what caused the most follow ups.

Genuinely curious to hear real experiences.
