Wedding RSVP deadlines and reminders: a plan that works
The reply date is a promise to your caterer and your hall. Setting it well, and nudging politely, saves you a phone call to every house in the last week.
Work backwards from the headcount
Ask the hall and the caterer for the date they need a final number, and set your RSVP deadline at least a week before it. That week is for chasing the guests who have not replied.
Local norms differ, so check with your planner, but a deadline roughly two to four weeks before the wedding is a sensible default for most families.
Say the date everywhere
Put the deadline on the invitation, on the RSVP page and in the message you send. A guest who sees the date three times does not have to guess.
Dawati's RSVP page tells each guest until when they can change their answer.
A reminder schedule
A polite pattern: the invitation, a first reminder a week after you send it if there is no reply, a second about a week before the deadline, and a final personal call or message two or three days before.
Reminder mode in Dawati lists those who have not replied and prepares a WhatsApp message for each in your wording. You choose when to send.
Tone matters
Keep the reminder warm and short, with the link in it. 'We would love to know if you can come' works better than 'You have not replied'.
For elders and close family, call. A link is a convenience, not a replacement for a conversation.
When nobody answers
After the deadline, treat a guest who has not replied as uncertain, and decide in advance whether you will count them or not. Tell your caterer your plan so the number is honest.
Allow a small margin for late replies and for guests who bring family members you invited by household.
