Online Wedding Invitations + RSVP — Invite via LINE, Count Guests Automatically
Remember the ritual of messaging every guest on LINE, one by one, and jotting the count on paper? Online wedding invitations (e-invitations) with an RSVP button exist to erase that. Share one over LINE in seconds, guests open it on their phones, confirm attendance themselves, and the count flows into your system automatically.
Here's what an online card is, what it should include, and how to make the counting happen on its own.
What is an online invitation, and how does it differ from paper
Put simply, it's a single web link you can open on a phone — the event details, a map, and usually a built-in reply button. Here's how it beats paper:
- Easy to share — copy one link and invite via LINE / Messenger / IG instantly
- Updatable — change the time or venue and the same link updates for everyone
- Auto-counting — with an RSVP button, replies are totalled for you
- Cheap and green — no per-copy printing cost
What to include in an online invitation
| Item | Detail |
|---|---|
| Couple's names | Nicknames/full names as you want guests to see them |
| Date and time | Separate the morning ceremony and evening reception clearly (Thai weddings often have both) |
| Venue + map | A pin that opens Google Maps for navigation |
| RSVP button | To confirm attendance + headcount |
| Dress code / theme | If any, it helps guests match the event |
| Contact | In case guests have questions or changes |
If you're holding both a morning ceremony and an evening reception, list them on clearly separate lines and note which guests are invited to which — elders usually to the morning, friends to the evening — so no one turns up confused about the time.
RSVP — the heart of an online card
RSVP is simply guests confirming whether they'll attend and how many. The payoff is an accurate count for:
- Locking table and catering numbers (see Chinese Banquet Seating)
- Estimating favours accurately (see Wedding Favours)
- Knowing bride's/groom's side counts for seating
Versus chasing replies one by one over LINE and noting them yourself, a card with a reply button collects the totals automatically, cutting both the work and the errors — read more on counting guests accurately in How Many Invitations & Counting Guests.
Paper vs online — using both is best
You really don't have to pick one. Plenty of couples run both at once:
| Type | Good for |
|---|---|
| Paper | Senior relatives, elder guests — formal, respectful, a keepsake |
| Online + RSVP | Friends, colleagues, younger guests — easy over LINE, auto-counting |
Tip: print a QR code on the paper card that scans to the online card to RSVP — you get both formality and easy counting in one piece.
When to open RSVPs
- 2–3 months out: send invitations and open RSVPs (matching the Wedding Checklist)
- ~1 month out: chase non-responders, then confirm the final count
- After closing: lock tables, catering and favours, and arrange seating

Summary
An online invitation with an RSVP button lets you invite over LINE instantly, count automatically, and update details anytime — include everything (separate morning/evening times, a map, a reply button), pair it with paper for elders, and open RSVPs early. That's how you get an accurate guest count without chasing everyone one by one.
Frequently asked questions
What is an online wedding invitation?
It's a digital invitation that is a web link, viewable on a phone. It usually shows the event details, a map, and a button for guests to RSVP, and can be shared over LINE or social media instantly — no printing needed.
Can an online invitation fully replace paper?
Yes, and it's increasingly popular, but many couples use both — paper for senior relatives for formality, and online for friends and colleagues for easy inviting and counting.
How does RSVP on an online card work?
Guests tap a button on the card page to confirm whether they'll attend and how many. The system collects the totals automatically in real time, giving a much more accurate count for locking tables, catering and favours.
What should an online invitation include?
Names of the couple, date and time, venue with a map, a rough schedule, dress code, a reply button, and contact info. For a Thai wedding, list the morning ceremony and evening reception with separate times.
