Is the waiver tied to their email?

Understand how waivers link to guest identity for sauna and cold plunge operations at the desk.

ZettlorUpdated August 26, 2026

Waivers match the guest by email or phone on their profile. Each signed waiver stays tied to that individual guest for legal purposes. Signing applies to the person, not a household—guests without email cannot receive an invite.

What Zettlor does today

You search by email or phone to find waiver status on a guest profile. The signed waiver keeps the guest name and contact on file. Remote invites require an email address on the guest record.

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

Look up the guest by email or phone in CRM → Customers before check-in. Send a waiver invite only when email is on file; otherwise use Sign waiver at the sauna and cold plunge entrance.

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

Typos or duplicate profiles split waiver history across records. Guests without email cannot be invited remotely, which slows door flow if you rely on email-only outreach.

Operator example

At Reddit NYC, desk staff search cold plunge arrivals by phone when email is missing, then use Sign waiver on the matched guest profile.

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. Search CRM → Customers by the guest email or phone.
  2. Confirm the profile shows the correct signed or pending waiver templates.
  3. Send a waiver invite only when a valid email is on the guest record.
  4. Use Sign waiver when the guest has no email and cannot receive an invite.
  5. Use Merge Customer if waiver history is split across two contacts.

Does one signed waiver cover everyone in a household?

No. Waivers attach to the individual guest. Each sauna and cold plunge attendee needs their own signed waiver on file.

Unsigned guests without an email on file cannot get an invite. Collect email at the desk or complete Sign waiver instead.
