Wedding Guest Etiquette 101: The Do’s and Don’ts of RSVPing

RSVPs may seem like a small detail, but when it comes to planning a wedding, they’re incredibly important. As a wedding venue owner, I not only speak with a lot of engaged couples, but I also follow numerous wedding planning groups on social media. Time and time again, I’m reminded why RSVP etiquette plays such a crucial role for guests.

It’s not uncommon to see a plus-one suddenly turn into a plus-two—without the couple’s knowledge—or to hear stories of guests encouraging others to reach out and ask why they didn’t receive a wedding invitation (that was never actually sent). Let’s stop being presumptuous. Most wedding venues have limited seating, and most couples are working within a carefully planned wedding budget. Ignoring RSVP etiquette can lead to stressful situations, unnecessary expenses, and last-minute complications for both the couple and their wedding vendors.

Whether you’ve recently received a wedding invite or you’re trying to be a more thoughtful guest, here are the RSVP do’s and don’ts every wedding guest should know.

RSVP Do’s for Wedding Guests

1. RSVP On TimeThis might seem obvious, but it's one of the most commonly ignored rules of wedding guest etiquette. Couples typically need a final headcount weeks in advance to finalize seating charts, catering, and more. Check the RSVP deadline and respond promptly—ideally, as soon as you receive the wedding invitation.

2. Use the RSVP Method RequestedIf there’s a pre-stamped RSVP card, send it back by mail. If there’s an online RSVP link, use it. Following the couple’s preferred method makes the wedding planning process much smoother.

3. Only RSVP for Those Named on the InvitationWedding invitations are addressed with intention. If it says “John Smith,” don’t RSVP for “John Smith + Guest” unless the invitation specifically states you have a plus-one. Respecting the guest list is essential.

4. Share Dietary Restrictions When PromptedIf there’s a spot to indicate dietary needs, don’t ignore it. Be honest and brief, noting any allergies or restrictions that the couple and caterer need to know about. This helps ensure your meal fits within the wedding menu planning.

5. Show AppreciationA small thank-you in your RSVP or a kind note goes a long way. The couple has chosen to include you in one of the most important days of their lives—it’s thoughtful to acknowledge that.

RSVP Don’ts for Wedding Guests

1. Don’t Miss the DeadlineWaiting until the last minute—or not responding at all—puts couples in a difficult spot. They may need to chase down responses, guess your intentions, or make last-minute decisions about their wedding guest count. Avoid the awkwardness and respond on time.

2. Don’t Assume You Have a Plus-OneUnless your invite says “and guest,” you were likely invited solo. Adding a guest without permission can disrupt seating arrangements and stretch the couple’s carefully planned wedding budget.

3. Don’t Make Last-Minute ChangesOnce you’ve RSVP’d, stick to it. Emergencies happen, but changing your mind at the last minute—or worse, showing up after RSVPing "no"—can cause major disruptions with catering, seating, and wedding timelines.

4. Don’t Add Unsolicited Notes or RequestsThe RSVP card is not the place to request special songs, ask about menu changes, or inquire about bringing children. Stick to the information requested and direct any extra questions through the couple’s wedding website or appropriate communication channels.

5. Don’t Pressure the Couple About InvitesIt’s not appropriate to question why someone wasn’t invited or encourage others to reach out about attending. Wedding guest lists are often sensitive and closely tied to the couple’s budget and venue capacity. Please respect their decisions.

Final Thoughts on Wedding RSVP Etiquette

RSVPing to a wedding invitation is one of the simplest and most respectful ways to support a couple during their wedding planning journey. It's more than checking a box—it’s a gesture of consideration, gratitude, and good manners.

The next time you receive a wedding invitation, respond quickly, follow the couple’s instructions, and never make assumptions. By doing so, you’re helping the couple enjoy a joyful, stress-free wedding day—and that’s truly something to celebrate.
