SMS Opt-In
Short definition
SMS Opt-In: A recorded recipient permission to receive a specified category of text messages.
Meaning and how it works
Opt-in should cover the relevant message purpose and be recorded in a verifiable way rather than inferred from a stored number. Mobile messages travel through carrier networks and messaging platforms. Channel, encoding, templates and route limits affect delivery, timing and cost.
Business applications
- Business scenario:
At registration, a customer grants separate consent for marketing texts where required.
What to check before implementation
Before sending, check recipient consent, contact accuracy, character limits, delivery reporting and a convenient opt-out for marketing messages.
