Why SMS Compliance Matters
Sending text messages for business purposes, including call sheets, is regulated by federal law (TCPA) and carrier requirements. G-Casper Pro handles most of the compliance automatically. Understanding the basics protects you if something goes wrong.
Opt-In Requirements
Before you can send SMS call sheets to someone, they must opt in (agree to receive messages). G-Casper Pro provides two ways to collect consent:
| Opt-In Method | How It Works |
|---|---|
| Production Invite | When a crew member is invited to the production, they can opt in to SMS notifications as part of accepting the invite |
| Deal Memo | Consent is collected as part of the deal memo paperwork during onboarding |
STOP Keyword Handling
By law, anyone can opt out of receiving your messages by replying 'STOP.' G-Casper Pro handles this automatically:
- When someone replies STOP, they're immediately unsubscribed
- They receive a confirmation that they've been unsubscribed
- Their crew profile is updated to show 'SMS Opted Out'
- They won't receive future SMS call sheets unless they re-subscribe
- You're notified when a crew member opts out
A2P 10DLC Compliance
A2P (Application-to-Person) messaging using 10DLC (10-digit long codes) is the compliant way to send business SMS in the US. G-Casper Pro is fully registered and compliant:

What Your Messages Must Include
Every SMS call sheet sent through G-Casper Pro automatically includes required elements:

- Clear purpose of the message (call sheet notification)
- Opt-out instructions on first message of each production
- Link to full terms if crew hasn't seen them
International Considerations
If you're sending call sheets to crew with international numbers, additional regulations may apply. G-Casper Pro supports international SMS with country-specific compliance. Contact support for guidance on specific countries.
