Compliance message in the initial texts

Noticed an opt-out line attached to your outgoing texts? CallHub adds it automatically to meet US carrier regulations, and drops it once the contact replies. This article explains when the line appears, when it stops, and why you don't need to write it yourself. It applies to Peer-to-Peer Texting and Text Broadcast campaigns.

How it works

Carriers classify your messages by whether the contact has replied yet:

Before the contact replies, every message is classified as promotional, and promotional messages must carry an opt-out option. CallHub automatically includes the compliance message, such as "Reply STOP to unsubscribe," in your initial text and in any follow-ups, until the contact responds.

Once the contact replies with anything except STOP, the conversation becomes two-way. Messages are then classified as conversational, the opt-out line is no longer required, and CallHub stops adding it.

Implementation in CallHub

CallHub has integrated these guidelines into both Peer-to-Peer Texting and Text Broadcast campaigns. The system automatically includes the opt-out message in the initial and follow-up messages until the recipient responds.

Example

Initial message sent:

"Hi John, we'd love to share updates about our campaign. Reply STOP to unsubscribe."

John replies with any message except STOP. Future messages no longer include the opt-out line:

"Hi John, thanks for your response! Here's the next update on our campaign..."

The conversation stays natural once engagement begins, and every message before that stays compliant.

Notes & limits

ⓘ It applies to both texting campaign types. Peer-to-Peer Texting and Text Broadcast campaigns both add the compliance message automatically.

✓ You don't need to write STOP language yourself. CallHub includes the opt-out option in every initial and follow-up message until the contact responds, so your campaigns meet carrier regulations and contacts always have an easy way to unsubscribe.

FAQs

When does the opt-out line stop appearing? 
As soon as the contact replies with anything except STOP. From that point the exchange is conversational and the line is no longer added.

Can I remove the line from my initial texts? 
It's there to meet a carrier requirement: messages sent before a contact replies are promotional and must carry an opt-out option. CallHub includes it automatically so your campaign stays compliant.

What happens if the contact replies STOP? 
They're unsubscribed and won't receive further messages from the campaign. See Best Practices for managing message filtering and opt-outs for how opt-outs are handled.
