For individuals or organisations sending direct marketing message via SMS:
There are three steps to follow when sending out SMS messages for promotional campaigns:
You should only be sending out bulk SMS messages to customers who have consented to receive marketing messages from you. There are two types of consent:
Express consent – the message recipient has specifically requested messages from you/your company or organisation.
Inferred consent – there may not be a clear indication of consent, but due to an existing relationship with the customer, it is expected that you/your company will contact said customer.
Your messages need to clearly indicate the person, company or organisation that is sending the message.
You should always offer the recipient the option to stop receiving your communications, allowing them to indicate that they no longer wish to receive SMS messages from you/your company or organisation.
