What is this tool and how does it work?
How does the SMS Segment Calculator estimate cost and delivery length?. It checks every character for GSM-7 compatibility, highlights UCS-2 trigger symbols, visualizes concatenated segment boundaries, and can auto-normalize text to GSM-7.
Common Use Cases
- Reducing campaign costs in Twilio and GoHighLevel by removing UCS-2 trigger characters.
- Auditing long SMS copy with visual segment maps before launching automations.
- Validating segment previews inside CRM workflows to avoid billing surprises.
