How do I send an updated waiver to guests who already have a booking?

Push revised waiver templates to booked sauna and cold plunge guests with pending or expired signatures.

ZettlorUpdated August 26, 2026

When you publish a new waiver version, use send-waiver or bulk send for guests whose status is pending or expired. Booked guests with email on file can sign before arrival without redoing the whole booking.

What Zettlor does today

Send-waiver targets individual guests or bookings, and bulk actions cover pending or expired waiver status for upcoming bookings. Guests need email on file to receive the updated document.

This behavior is live in Zettlor today for a commercial sauna and cold plunge room. Guest booking, cancel, and credit self-serve steps stay on Help. This page is for operators.

Desk path

From Scheduling → Waivers or the guest profile, send the updated template to booked guests, or run bulk send for upcoming sauna and cold plunge sessions with outstanding signatures.

Do not invent a settings path beyond what is listed here. If the product does not include a control, the desk workaround is the path.

Failure mode

Guests without email still need Sign waiver at the door. Sending an update does not void old signed copies until the new template is required and completed.

Operator example

At Reddit NYC, operators bulk-send an updated session waiver to tomorrow's sauna bookings after liability language changes, then use Sign waiver for any unsigned walk-ins.

A sauna and cold plunge operator can copy the shape of this example without copying another brand's private pricing or customer lists.

How to do this

  1. Publish the updated waiver template in Scheduling → Waivers.
  2. Filter upcoming bookings or guests with pending or expired waiver status.
  3. Send the updated waiver to individuals or use bulk send for a session block.
  4. Confirm signatures on the guest profile before sauna and cold plunge check-in.
  5. Use Sign waiver for booked guests who arrive unsigned or without email.

Who receives an updated waiver send?

You target guests with pending or expired status on the relevant template. Guests who already signed the current version may not need a resend unless you require re-signing.

Can I bulk send to everyone on tomorrow's schedule?

Yes. Use bulk send from waiver tools for upcoming bookings that still show pending or expired on the updated template.
