RSVP etiquette

RSVP etiquette is the set of contemporary expectations around replying to an invitation, the timeline (within two weeks of receiving, never later than the printed deadline), the form (in the same medium the invitation was sent), the obligation (replying yes or no rather than leaving the host guessing), and the small grace notes (a handwritten card for a formal invitation, a brief explanation for a regret), and although the rules have loosened in app-mediated invitations the expectations themselves have not

RSVP etiquette is the body of small expectations around replying to an invitation, the abbreviation comes from the French répondez s'il vous plaît, please reply, and the etiquette is older than any of its current forms.

The contemporary RSVP environment is mixed: formal weddings still use printed reply cards, casual gatherings use texts and Paperless Post, work events use calendar invites. The form has loosened; the substance has not, the host needs an answer in order to plan, and the obligation to give one is the same regardless of the medium.

The timeline

Formal wedding invitations carry a printed RSVP deadline, typically four to six weeks before the event, set so the couple can give a final headcount to the caterer. Reply within two weeks of receiving the invitation if possible, and never later than the printed date. Less formal invitations (a dinner, a baby shower, a holiday party) deserve a reply within a few days, certainly within a week. A reply that arrives after the host has already had to assume an answer is awkward for everyone and is usually too late to count.

The form

Reply in the same medium the invitation arrived in: a printed reply card by mail, a Paperless Post reply on Paperless Post, a text in response to a text. The traditional handwritten reply card for a formal wedding (third-person formal, Ms. Jane Doe accepts with pleasure) is still appropriate at black-tie events. For everything else, plain language is fine. The point is to give the answer clearly enough that the host can count on it.

The grace notes

A regret deserves a brief explanation (so sorry, we will be out of town that weekend) but not a long one; the host is grateful for the no but does not need a paragraph of justification. An acceptance can include a short personal note (so excited for you both). And if circumstances change after replying yes, tell the host as soon as possible, the late cancellation is much easier to absorb than a no-show that has already been paid for. See plus-one etiquette for what to do about bringing a partner who was or was not invited.
