Wedding Invitation Checklist by Month: What to Send and When
Set the whole timeline before you order anything
Invitation planning works best when you count backward from the wedding date rather than forward from today. Start with your venue's final headcount deadline, usually two to three weeks before the wedding, then build backward so every RSVP, follow-up, and seating chart has room to breathe. Most couples need four distinct mailings over the course of a year: save-the-dates, the formal invitation suite, a details or rehearsal card, and finally thank-you notes. Keep one master guest list in a spreadsheet with columns for household name, mailing address, RSVP status, and meal choice — you will reuse that same file at least five times.
Save-the-dates: 8 to 12 months before
Send save-the-dates 8 to 12 months out, and at the full 12 months for destination weddings, holiday weekends, or venues that book up a year in advance. The job of a save-the-date is logistics only: date, city, and a link to your wedding website. Skip the formal wording, the ceremony time, and the RSVP request — guests cannot RSVP to an invitation they haven't received yet.
- Mail to confirmed guests only, including plus-ones you're certain about. It's awkward and expensive to retract a save-the-date later, but a quick note that travel plans are now finalized is fine.
- Order 10–15% more than your current guest count. For a 120-guest wedding, that's 132–138 cards.
- Budget roughly $1.50–$3 per card printed and mailed, versus $5–$10 for a full invitation suite.
- Check with your stationer that the cards fit a standard letter envelope — oversized pieces cost extra postage.
The formal invitation: 6 to 8 months out
Mail formal invitations 6 to 8 months before the wedding. For a local wedding where nearly everyone lives within a two-hour drive, 8–10 weeks out is sufficient and keeps the suite feeling fresh. Destination or holiday-weekend weddings should go out earlier — 10 to 12 months — because guests need time to book flights and accommodations.
Order your suite at least four to six weeks before your mail-by date. Printers run on proofing, revision, and mailing timelines, and you want a 10-day buffer before the envelope hits the post office. Include 10–15% overage for mistakes; one spelling error in a 100-name list is statistically likely, not a worst case.
- Order outer envelopes, inner envelopes, reply cards, and pre-printed reply envelopes with your return address. Use first-class postage on reply envelopes — business reply postage can delay processing.
- Print a sample suite and address a few envelopes by hand before committing to the rest.
- Add a first-class stamp rather than metered postage; it reads as more personal and avoids surcharges.
At a glance: the mailing timeline
| Stationery | Mail by | RSVP or follow-up |
|---|---|---|
| Save-the-dates | 8–12 months before the wedding | Guests set dates, no RSVP needed |
| Formal invitation suite | 6–8 months before (10–12 months for destination) | Reply by 2–3 weeks after mailing |
| Details / rehearsal card | 2–4 weeks before | Reminder call or email to non-responders |
| Escort cards and menus | Completed 1 week before | Final headcount to venue 1–2 weeks before |
| Thank-you notes | Within 3 months of the wedding | Track gifts received as they arrive |
RSVP deadlines: give guests a real number
Set your reply deadline 2 to 3 weeks after the invitations mail, and no later than 3 to 4 weeks before the wedding. Your venue's final headcount is the hard constraint; if that deadline falls on the 15th, ask guests to reply by the 21st at the latest and build in time to chase stragglers. Name the deadline explicitly on the reply card — "Please reply by March 12" outperforms "Kindly reply soon" every time.
For 100 guests, expect roughly 80–85% of replies in the first week, another 10% within three weeks, and a stubborn 5–10% that you'll have to track down. Send a friendly follow-up by phone or text at the two-week mark, then a second one a week before the venue's cutoff.
Details cards and final inserts
A separate details card keeps the main invitation clean and lets you update information late. Include ceremony and reception addresses, hotel room block codes, parking or shuttle information, attire guidance, and your wedding website URL for RSVPs and gift registries. Print it 2–4 weeks before the wedding so it reflects any last-minute schedule changes — that's the window where venue logistics actually settle.
After the RSVPs: turn numbers into orders
Convert RSVPs into a firm headcount the week the deadline closes, and give it to your venue and caterer immediately. Confirm final meal counts, allergy notes, children's meals, and vendor meals with the kitchen. Build your seating chart from the confirmed list, not the invitation list — people decline for legitimate reasons, and over-ordering meals is one of the most common ways couples overspend.
Thank-you notes
Thank-you notes should go out within three months of the wedding, and within two weeks for engagement and shower gifts. Write them as gifts arrive rather than in one post-wedding marathon; a running log by guest name makes the task manageable. Use the same guest-list spreadsheet, add a "gift received" column, and note any registry or handwritten detail so each note feels specific rather than generated.
Frequently Asked Questions
How far in advance should I send invitations for a local wedding? Eight to ten weeks before the ceremony is ideal. That gives guests enough time to clear their calendar, shop for gifts, and book childcare, while keeping the details card accurate. Sending more than four months out risks conflicts with other commitments people haven't made yet.
Do I need to send save-the-dates if I'm sending formal invitations early? Only if guests need to plan travel or accommodation. If your wedding is local, within six months, or you're not booking a destination venue, skip save-the-dates and spend that budget on the invitation suite itself.
What if someone doesn't respond by the deadline? Call or text directly about two weeks after the reply date, then follow up again a week before you confirm headcount to the venue. If you still hear nothing, count them as a no, and tell your planner so meal counts stay accurate. Don't wait for a polite answer that may never arrive.
