Start with a clean guest list source
Before sending invitations, confirm one source of truth for guest names, phone numbers, and optional email addresses. Avoid splitting the same list between multiple spreadsheets.
Use private links instead of group threads
A private RSVP link per guest keeps each response tied to one person and removes ambiguity when family members answer in shared chats.
Set RSVP deadlines early
Choose an RSVP deadline that gives you enough time to finalize catering, seating, and printed materials. Send your first reminder one week before that deadline.
Track pending guests daily during the final week
In the week before your deadline, check pending guests once per day and send targeted reminders to that subset only.
Export before handing off to vendors
Export the latest RSVP state before your final catering call and share a dated version with planners or family helpers.
