SMS
Turn conversations into customers
Send and receive business SMS from numbers owned by your account. Consent, carrier registration, and opt-out rules apply before production messaging scales.
- ✓ 1-to-1 SMS from owned local numbers
- ✓ Conversation history and delivery status
- ✓ Searchable message threads
- ✓ STOP / HELP keyword support for compliant opt-out
- ✓ Business verification required before outbound SMS
Consent and STOP
Only message people who opted in. Clearly identify your business at opt-in, keep consent records, and honor STOP, UNSUBSCRIBE, CANCEL, END, and QUIT promptly. HELP should return assistance information. See our SMS Policy for full requirements.
US 10DLC registration
Application-to-person SMS on US local numbers generally requires brand and campaign registration (10DLC). Accurate brand details and use-case descriptions are required. Unregistered or misrepresented traffic may be filtered or blocked by carriers.
Toll-free messaging verification
Where toll-free SMS is offered, carriers typically require toll-free verification before messages are accepted. Toll-free voice on MyProCaller remains inbound only — it cannot be used as outbound Caller ID.
