Online invitations with RSVP: how they work and what to look for

How online invitations with RSVP work, text versus email delivery, what guests see, the features worth having, the questions to ask about cost, and privacy.

Online invitations have replaced paper for most parties, and for good reason: they arrive in seconds, guests answer in a tap, and you always know your head count. But they’re not all alike. Here’s how they work, what matters to your guests, and what to look for before you pick one.

How they work

An online invitation is a web page for your party. Each guest gets a link (by text, email or both) that opens the invitation in their phone’s browser. They read the details, tap yes, maybe or no, and the answer lands in your guest list. When plans change, the page changes, and everyone sees the latest.

The good ones give each household its own link. That’s what lets the invite greet them by name, remember their answer, and let them change it later, without anyone signing up for anything.

Text or email?

Both work; they work differently.

Text is read within minutes, and most people answer from their phone. It’s the best way to reach busy friends, grandparents and anyone whose inbox is a disaster.
Email is better for long guest lists and formal events, and it’s easier to send to people whose numbers you don’t have.

Many hosts send both. One thing matters more than people expect: who the text comes from. A text from a number your guests already know looks like you; one from an unfamiliar number can look like spam, and some phones tuck unknown senders into a separate folder.

What guests should never have to do

Download an app. An invite should open in any phone’s browser.
Make an account or a password just to say yes.
Wade through ads for other parties or products.
Guess. The date, time, address, parking and dress code should be right there.

If a service asks guests for any of those, expect fewer answers and more “did you get my text?” messages.

Features worth having

Not every party needs every feature. Match them to yours:

RSVPs by name, with a question for each person (meal choice, allergies), for dinners and weddings.
Kids counted separately, so you order the right number of chairs and pizzas.
Plus-one limits, set for the party or guest by guest.
Reminders and nudges: a “can you make it?” to whoever hasn’t answered and a reminder to the yeses before the day.
Updates to everyone, or just to the people coming, when something changes.
A head-count limit and a waitlist, for a room that holds 40.
A what-to-bring list, for potlucks.
Who’s opened it, so you know who to nudge in person.
Calendar and maps buttons, so guests don’t have to type anything.
Larger text and time zones, for older guests and family far away.

For a wedding, add a seating chart, the registry and hotel links, a wedding website, and one invite for a weekend of events.

Questions to ask about cost

Pricing varies more than the invitations do. Before you design anything, find out:

Is there a free version, and how many guests does it cover?
Do you pay per party, per guest, per invitation design, or by the year?
Do texts cost extra, or come from your own phone?
Are reminders, guest-list features or designs behind a higher plan?
Will your guests see ads on a free plan?

Privacy

Your party’s address and your guests’ names and numbers are private. Look for:

the address shown only to invited guests, not on a public page anyone could find;
no selling or sharing of guest information;
a way to turn off sharing for a surprise party;
your guest list exportable, so it’s yours to keep.

How letsparty works

letsparty gives each household its own link, texted from your own phone (one tap sends them all from an iPhone) or emailed, with the guest’s name on the envelope. Guests never need an app or an account. RSVPs come in by name with meal choices and kids counted on their own, nudges and reminders go out by themselves, and the address shows only on invited guests’ links. It’s free for small parties, with one price per bigger party.

A quick checklist

Pick text, email or both, based on how your guests read.
Check that guests won’t need an app or an account.
Choose the features your party needs, not every feature there is.
Compare what it costs for your guest list, texts included.
Make sure the address stays private.
Send a test to yourself before you send it to everyone.
