What is SMS Marketing & How Does it Work?
To receive text message specials, new product updates or more information, customers are usually required to opt in to an automated system by texting an initial shortcode. When the 5 digit code is texted, that user’s phone number is then stored by whatever SMS marketing software is issuing the texts. A confirmation response is usually sent as receipt for opting in, with an opt-out code included for potential future unsubscribing.
