SMS Opt-In Compliance

What G-Casper Pro records about text message consent, how STOP works, and what stays the production's job.

4 min readUpdated September 2026

US rules on business texting expect the sender to have the recipient's consent before texting them. G-Casper Pro sends the texts, but the production gathers the consent. The software asks you to confirm you have it, records opt-ins it collects itself, and honors STOP.

Important: G-Casper Pro does not stop you texting someone who has not opted in. Only a number that replied STOP is blocked. Text only people who agreed to it.

How Opt-In Management Works

Three things are recorded:

  • Your certification. The first time you send by SMS, the SMS Consent Required dialog asks you to confirm you have prior express consent from each recipient. I Agree & Continue records it on your account, once
  • The invite opt-in. The Mail icon on a crew, cast or background row sends an email invite. The person confirms their contact details and can tick Yes, send me SMS reminders for call sheets. G-Casper Pro stores the time they did
  • Opt-outs. A reply of STOP, STOPALL, UNSUBSCRIBE, CANCEL, END or QUIT blocks that number. START, YES or UNSTOP lifts the block
Tip: The Mail icon turns green once the person has opted in to SMS on the invite page. Hover it to see SMS opt-in confirmed.

Not sent

STOP Covers Every Production

An opt-out belongs to the phone number, not to one show. Once a number replies STOP, no production on G-Casper Pro can text it until it replies START. The invite opt-in, on the other hand, is per production: a copied production starts with nobody opted in. Every text ends with Reply STOP to opt out, HELP for info.

Many productions collect SMS consent in the deal memo or start paperwork. That is a sound record, and it stays in your paperwork: G-Casper Pro has no switch to mark someone as opted in by hand. The row's green icon only reflects the invite page. Sample wording for a start packet:

Tip: Sample SMS consent clause: "I consent to receive production-related text messages, including daily call sheets, schedule updates, and location information, sent by [Production Company Name] via G-Casper Pro to the mobile number I have provided. I understand that message and data rates may apply, and that I may revoke this consent at any time by replying STOP to any message or by notifying the production office."
