MessageDesk Compliance Center

Set how your workspace handles SMS opt-outs, opt-out confirmations, signatures, and STOP keywords. Clearly and carrier-friendly.

​
Access the Compliance Center

Go to Account → Settings → Compliance Center (under Workspace Settings).
If you don’t see Compliance Center, your role may not include access. Ask an Admin or Manager.

SMS compliance overview

The Overview tab covers U.S. SMS compliance basics and recommended practices. By law, when sending business text messages in the United States, you must follow these guidelines:
  1. Don’t send any SHAFT-C-related content.
  2. Only message contacts who’ve opted in to receive messaging from you.
  3. Respect opt-out. When contacts reply “STOP,” don’t send any additional messages.
  4. Don’t send messages outside of normal business hours.

​
How MessageDesk helps keep you compliant

MessageDesk automatically enforces:
  1. “Reply STOP to opt-out” for every contact who replies STOP at any time.
  2. Opt-out tracking for each number across your entire workspace.
  3. When contacts opt out of messaging, MessageDesk tracks this for you.

​
Opt-out configuration

MessageDesk gives you two ways to configure opt-out.

​
1. Inbox Opt-Out (carrier-preferred)

If a contact opts out on one phone number, they’re blocked from every number in your workspace. When to use. Works best for most teams: single standard, fewer compliance mistakes, can produce better deliverability.

​
2. Phone Number Opt-Out

If a contact opts out of messaging from one number, they can still receive texts from other numbers in your workspace. When to use. Each number serves a distinct audience or purpose (with separate consent). Opt Out Configuration Pn

​
Opt-out confirmation

Opt-out confirmation sends a message confirming the contact has opted out. Fine-tune what the contact sees immediately after they unsubscribe. What happens by default
  • MessageDesk sends an automatic confirmation acknowledging the opt-out.
  • The conversation shows an opt-out banner, and future sends are blocked.
Edit the opt-out confirmation:
  1. Click Edit.
  • Edit the message to include a confirmation that the contact has opted out, plus a brief note about how to opt back in (see “Re-opt in” below).
Opt Out Confirmation Pn

​
Opt-out signature

Add a standard opt-out line (“Reply STOP to opt out.”) to every sent message. Improves clarity and helps you meet carrier expectations. Options:
  • Apply to all sent messages (carrier-preferred). Most compliant. Least confusing for recipients.
  • Include once per conversation. Adds the signature only to the first outbound message in a thread.
How to set. Settings → Compliance Center → Opt-Out → Signature. Tips:
  • Keep it short and standard: “Reply STOP to opt out.”
  • Pair with your business/organization name when appropriate for context.
Opt Out Signature Pn

​
STOP keywords

MessageDesk manages opt-outs automatically when a contact replies with a supported keyword:
  • stop
  • unsubscribe
Variations (case/spacing) are supported.
What you’ll see
  • The contact gets an automatic confirmation.
  • An opt-out notice appears in the thread.
  • Future sends are blocked based on your configured scope.

​
Opt-out best practices

  • Message only opted-in contacts.
  • Respect opt-outs immediately. Don’t follow with a “last message.”
  • Include opt-out language (signature) on non-conversational sends.
  • Avoid spam triggers. Generic short links, all caps, excessive punctuation.
  • Send during business hours when possible.

​
Troubleshooting

I can’t text a contact anymore.
They may be opted out. Check the opt-out banner in the thread and review scope in Compliance Center. Switching numbers didn’t bypass an opt-out.
You probably have Inbox Opt-Out enabled. Switch to Phone Number Opt-Out only if your compliance policy allows distinct consent per line. A contact wants to opt back in.
Ask them to send START (or another explicit consent message) from the same number. Confirm opt-in and resume messaging per your policy. Our messages are being filtered.
Turn on the opt-out signature for clarity, review content for potential spam triggers, and confirm your carrier registration status for each line.
