SMS Opt-Out Compliance

Understand how SMS opt-outs work so you stay compliant and respectful of your contacts’ preferences.

Under U.S. law (the Telephone Consumer Protection Act, or TCPA), you must honor a customer’s request to stop receiving text messages. If someone opts out, you can’t send them marketing texts unless they opt back in.


What Opt-Out Means

When someone asks to opt out, meaning they don’t want to receive your texts anymore, Salesmsg automatically stops sending them messages. This protects you and keeps you compliant with U.S. text marketing laws.


Automatic Opt-Out via Keywords

Contacts can unsubscribe at any time by sending common keywords like:

  • STOP

  • CANCEL

  • END

  • UNSUBSCRIBE

  • QUIT

  • STOPALL

Salesmsg will recognize these and unsubscribe the contact automatically - even if the contact makes a small typo (like stoppp).

💡 Quick tip: Make sure your messages always include simple opt-out instructions such as “Reply STOP to cancel.” This is not just good practice - it’s required.


Manually Unsubscribe Contacts

If someone asks you personally to be removed, you can manually unsubscribe them in Salesmsg:

  • From the Contacts page

  • Or in bulk from Contacts or Conversations pages

This gives you control if someone requests removal in another way (like email or call)


How Resubscribing Works

Contacts who previously opted out (e.g., by texting STOP) can opt back in by sending the following message:

  • START

  • YES

  • UNSTOP

However, this must come from the contact directly - you cannot resubscribe for them inside Salesmsg to remain compliant.


What Happens After Opt-Out

Once someone is opted out:

  • They won’t receive any triggers, broadcasts, workflow messages, CRM sends, or automation texts until they opt back in.

  • Salesmsg automatically skips them - you don’t need to take extra steps.

This keeps you compliant and protects your message deliverability.


Frequently Asked Questions

Will opted-out contacts receive any triggers, broadcasts, or CRM messages?

No. Once a contact opts out, they won’t receive any messages - including triggers, broadcasts, or CRM-driven campaigns, until they opt back in.

Salesmsg automatically skips opted-out numbers, so no messages are sent accidentally.

Can I customize the opt-out message?

It depends on the type of number you’re using.

  • Long Code numbers (standard 10-digit phone numbers):
    The opt-out messages are set by default and can’t be customized.

  • Dedicated Short Codes:
    You can customize opt-out messages. To make changes, contact our support team and they’ll help you review your options.

Can I export a list of opted-out contacts?

Yes. You can easily view and export them from the Contacts page:

  1. Go to Contacts

  2. Filter by Opt-in Status → Opted-out

This will show all contacts who have unsubscribed, which you can then export if needed.
