An SMS is a custom alphanumeric name (e.g., "BANK", "MYSHOP") that replaces a standard phone number in the "From" field of a text message.
Instead of asking, "Who is this?" the recipient immediately knows the source. This visual cue increases open rates by over 40% compared to standard SMS.
Using a custom Sender ID transforms a generic text message into a professional communication tool, building instant brand recognition and trust. In this comprehensive guide, we will explore everything you need to know about SMS with Sender ID, from what it is and how it works to the regulatory landscape and best practices for maximizing your ROI.
