SMS Opt-In Compliance Hub
Twilio A2P 10DLC Documentation & Process Explanation
Overview
This hub documents Simply Arrived’s SMS opt-in process for Twilio A2P 10DLC approval. All documentation below demonstrates TCPA compliance, prior express written consent, and a secure opt-out mechanism.
📋 Legal Documents
The following documents are live on our website and define our SMS practices:
🔗 Live Opt-In Page (Campaign Call to Action)
https://www.simplyarrived.com/opt-in
This is the actual, publicly accessible page where a staff member gives consent, and the Call to Action registered on our A2P 10DLC campaign. It requires no login, no token, and no invite code to view. The full SMS program disclosure — program name, message types with an example message, message frequency, “Message and data rates may apply,” STOP and HELP instructions, and links to our Privacy Policy and Terms — is rendered in the page’s server HTML and is visible without executing JavaScript.

📖 SMS Opt-In Explained
Plain-English guide to the opt-in process for staff members and administrators.

The consent screen itself, rendered read-only with sample details on the live opt-in page — no login or invite required. It uses the same components staff members use, so what is reviewed and what ships cannot differ. Text message, email and “don’t notify me” are equal choices, nothing pre-selected; the consent statement appears only after the staff member has verified their own mobile number with a one-time code.

- ✓Prior Express Written Consent — Staff must explicitly opt in via web form before SMS is sent
- ✓Easy Opt-Out — Reply STOP (or OPTOUT, CANCEL, END, QUIT, UNSUBSCRIBE, REVOKE, STOPALL) to any SMS, or contact your organization admin. Text messages contain no links.
- ✓Operational SMS Only — No marketing, promotions, or unsolicited messages
- ✓Complete Audit Trail — Every opt-in is recorded with timestamp, IP address and method. Every opt-out is enforced immediately at the carrier level by our messaging provider and recorded in our consent ledger
- ✓No Unsolicited SMS — Opt-in happens on the web, via an emailed link or an invite code. The only text sent before consent is the one-time verification code the staff member requests for their own number
- ✓Twilio Compliance — Using Twilio’s TCPA-compliant A2P 10DLC platform
