Take Control: Setting the SMS Sender in Workflows
GoHighLevel offers you direct control over which Twilio number sends an SMS message within your automated workflows. This is the most reliable way to ensure your leads receive messages from a specific, branded, or campaign-specific number, overriding any default system rules. Explicitly setting the 'From Number' in your workflows guarantees consistency and avoids confusion for your contacts.
For multi-location businesses or specific campaigns, assign unique Twilio numbers to each location or campaign. Then, consistently select these dedicated numbers in your workflows to maintain clear branding and message context.
Understanding GoHighLevel's SMS Sender Fallback Logic
When you don't explicitly specify a 'From Number' in a workflow, or if an SMS is sent outside of a workflow (e.g., manually by a user), GoHighLevel follows a specific hierarchy to determine which Twilio number to use. Understanding this fallback sequence is crucial for predicting sender IDs and troubleshooting unexpected numbers. This system aims to maintain conversation continuity and ensure messages are always sent, even if a preferred number isn't available.
⚠️ If the Twilio number chosen by any of these fallback rules is inactive, disconnected, or lacks sufficient balance, the SMS will fail to send. Always ensure your numbers are active and funded.
✅ The Channel Number is critical for a smooth customer experience. If it changes unexpectedly, contacts might miss messages or become confused, potentially impacting your engagement rates.
Regularly review and update your account's 'Default Outbound Number' in Settings → Phone Numbers to ensure it's an active, appropriate number. This acts as your safety net for all unassigned SMS communications.
