Legal Compliance and Considerations

When using a mass calling system, it's crucial to ensure compliance with applicable laws and regulations to protect both your organization and the recipients of your messages. Here are some key legal considerations to keep in mind when utilizing automated calling systems for mass outreach:


TCPA & DNC Compliance

Adhere to the Telephone Consumer Protection Act (TCPA) and Do Not Call (DNC) regulations. These laws regulate automated calling, ensuring you only contact individuals who have opted in and avoiding contact with numbers on the DNC list.


Opt-In & Opt-Out Requirements

Ensure that recipients have voluntarily opted in to receive your automated calls. You must also provide an easy way for them to opt-out of future calls, and this process should be made clear and accessible to all recipients.


Message Transparency

Identify your organization at the start of each call and ensure that your message is accurate and truthful. Avoid misleading recipients by providing clear and relevant information to make sure your outreach is transparent.


Acceptable Calling Hours

Comply with federal and state regulations regarding acceptable calling hours. Automated calls should generally be made between 8 AM and 9 PM in the recipient’s local time zone to avoid disruption during non-business hours.


Data Security & Privacy

Ensure that all recipient information is stored securely and that you comply with relevant data protection laws, such as GDPR or CCPA, to protect personal data and maintain privacy.


Emergency & Special Exemptions

Some calls, such as emergency notifications or public safety alerts, may be exempt from certain regulations. Ensure that these calls qualify for any exceptions and remain compliant with specific guidelines.

By following these best practices, you can use mass calling systems effectively while staying compliant with legal requirements. For more details, please consult the Sigma Voice Terms of Service
