Messaging

SMS terms and opt-in

Who sends these messages

Guesting is an event invitation and RSVP service operated by Flightcase App, Inc. at guesting.app. Contact support@guesting.app.

How invitations are sent

Guesting does not send invitations. A host builds an invitation, and Guesting gives them a link for each guest; the host then sends that link themselves, from their own phone, through their own messaging app. No invitation is sent over Guesting’s messaging service and no number is texted by Guesting because a host imported it.

How guests opt in

Opting in is separate from answering the invitation and is never a condition of it. The RSVP form asks for a name and Going, Maybe, or Can’t. It contains no mobile number field and no consent checkbox, and a guest can answer without ever giving us a number.

Underneath it, on every invitation and visible as soon as the page loads, sits a separate card headed “Want texts about this event?”. That card holds a mobile number field and a single consent checkbox that starts unchecked. Neither field is required, and a guest who ignores the card is never messaged. A guest who fills both is sent a one-time verification code, and the opt-in is recorded only once they enter that code back into the page — so consent is confirmed on the handset itself.

The card does not wait for an RSVP. Someone who wants a reminder but has not decided whether they are coming can opt in on its own, which is also why the whole opt-in — the checkbox, the message frequency, the rates disclosure, the STOP and HELP instructions, and the links to this page and the privacy policy — is readable at the invitation URL without submitting anything first.

This is the only way to opt in. Guesting does not use text-to-join keywords, paper forms, verbal consent, or purchased lists, and it never sends messages to a number that has not completed this card and its verification.

See it for yourself: https://guesting.app/demo is a permanent example invitation, open to anyone, with no sign-in. Scroll down and the opt-in card is there, exactly as every guest sees it.

This is the exact checkbox on that card, reproduced here:

I agree to receive text messages from Guesting about this event at the number above, including a one-time verification code and transactional updates such as reminders and host changes. Consent is not required to RSVP. Message frequency varies, typically 1–5 messages per event. Message and data rates may apply. Reply STOP to opt out, START to opt back in, or HELP for help. Terms · Privacy

The consent record is kept with the guest's response: the date and time they agreed, and the exact wording they were shown.

What we send

Transactional messages only, about the specific event a guest RSVP’d to. No marketing, no promotional content, no messages about other events.

• A one-time verification code confirming the guest’s number, sent when they ask for texts about an event.
• A reminder about that event, if the host enables reminders.
• An update from the host about that event, such as a time or place change.

Message frequency

Frequency varies by event. A typical guest receives one verification code and between one and five messages about that event.

Cost

Message and data rates may apply. Guesting does not charge for messages.

Opting out and getting help

Reply STOP to any message to stop all messages. Reply START to opt back in. Reply HELP for help, or email support@guesting.app.

Privacy

No mobile information is shared with third parties or affiliates for marketing or promotional purposes. Text messaging originator opt-in data and consent are never shared with any third parties. See the privacy policy and terms of service.
