How Guests RSVP Without an App or an Account
Guests do not need an app or an account to RSVP to a Blast invitation. They open the link you sent, watch the invitation, tap Going, Maybe or Can't, and type their name and email. That is the whole form. The reply lands on your host page and you get an email. This page explains what happens on the guest's side, what you see, and what to do about the people who never reply.
What the guest does
- Opens the link in whatever app it arrived in: a text, WhatsApp, email or a group chat. It opens in the phone's browser; there is nothing to install.
- Watches the invitation: the intro with the name, the video, the date and place, your note.
- Taps Going, Maybe or Can't. Going and Maybe ask for a name and an email, and for who is coming if you set that up. Can't asks only for a name, with a note if they want to add one.
- Can add the date to their calendar with one tap, and change their reply from the same link on the same phone.
What you see
Every reply appears on your host page as it arrives, with the name, the answer and any note. You also get an email for each one, so you do not have to keep checking. There is no app on your side either; the host page is a link you open in a browser, protected by a code sent to your mobile.
Why no app is the point
Every step between the invitation and the reply loses people. An app to download, an account to create, a password to remember: each one is a reason to put the phone down and forget. A reply that takes one tap and a name gets answered on the spot, often while the person is still looking at the invitation. The host's job is to make replying easier than not replying.
Guests who still do not reply
- Send the same link again a week before the party with one line: "Still hoping you can make it, the RSVP is in the link." Most late replies come from a second look, not a new invitation.
- Put a reply-by date in your note. People reply to deadlines.
- Ask the parents you know to reply first. A few early Goings make the rest feel like the party is happening.
- For a whole-class party where you have no numbers, see the guide on inviting a class without a phone list.

Do guests need to download anything to RSVP?
No. The invitation link opens in the phone's browser. Guests tap Going, Maybe or Can't and type a name and an email. No app, no account, no password.
Does Blast ask guests for a phone number?
No. The RSVP takes a name and an email. A guest who can't come leaves only a name, with a note if they want.
Can a guest change their reply?
Yes. The same link opens their reply, and they can change it. You see the latest answer on your host page.
How do I see who is coming?
On your host page, a link protected by a code sent to your mobile. Each reply also arrives by email.
Is RSVP tracking free?
Yes. Creating the invitation, sending it and collecting replies are free, with no subscription.
