How do you word an RSVP card to say 'please reply'?

The simplest way to ask for a reply is to use a clear, polite phrase. You can write: 'Please reply by [date]' or 'Kindly respond by [date]'. Add the method, such as 'by post to [address]', 'by email to [address]', or 'via our wedding website at [address]'. If you want to be firmer, you can add: 'We would be grateful for your reply by [date] so we can confirm numbers with our venue.' This is helpful because guests understand why the deadline matters. You can also add a line for those who cannot attend: 'If you are unable to attend, we would still love to hear from you.' This makes the card feel kind and inclusive. Avoid using 'RSVP' alone, as some guests may not know what it means. Write the full phrase 'Please reply' or 'Kindly reply' in bold. You can also add a small note: 'No reply is assumed as a decline after [date]' but only if you are comfortable with that.
