Terms & SMS Policy

Last updated: September 30, 2026

The service

MatrixSMS is a private messaging inbox operated by Matrix Anchor. It lets authorized users send and receive text messages through their own Twilio account and phone numbers. Accounts are created by an administrator; by signing in you agree to these terms.

Acceptable use

You agree to use MatrixSMS only for lawful messaging and to comply with all laws that apply to text messaging, including the U.S. Telephone Consumer Protection Act (TCPA), CAN-SPAM where relevant, carrier rules and Twilio's Acceptable Use Policy. You must not send spam, unlawful, threatening, deceptive or harassing content, and you must not message people who have not agreed to hear from you or who have opted out. You are responsible for the content you send and for keeping your login secure.

SMS messaging policy

Program: MatrixSMS is used by businesses and individuals to hold one-to-one text conversations with people they already have a relationship with — for example customers replying to a quote, appointment, order or service request.

Your account

Keep your password confidential and tell us promptly if you believe your account has been accessed without permission. An administrator may suspend or remove accounts or numbers at any time, including for misuse.

Your Twilio account

MatrixSMS works with a Twilio account that you or your administrator provide. Charges from Twilio and your carrier are separate from MatrixSMS and are your responsibility. You are responsible for the registration and compliance requirements that apply to your numbers, such as A2P 10DLC registration for U.S. messaging.

Availability and changes

We work to keep the service running but do not guarantee uninterrupted or error-free operation, and message delivery depends on Twilio and mobile carriers. We may change or discontinue features, and we may update these terms by changing the date above.

Disclaimer and limitation of liability

The service is provided "as is" without warranties of any kind. To the fullest extent permitted by law, Matrix Anchor is not liable for indirect, incidental or consequential damages, or for lost profits or data, arising from use of the service, and our total liability is limited to the amount you paid for the service in the preceding twelve months.
