## Overview

SMS/MMS is an efficient method of marketing and communication for businesses. Similar to email marketing, SMS/MMS marketing is the process of using text messages to communicate with customers about valuable information concerning your business. What makes it so impactful is that it is a permission-based marketing channel, which means customers have to give their permission (i.e., opt-in) to reap its benefits. Factoreal has a dedicated SMS/MMS marketing suite. Follow this overview to understand the requirements you need to comply with before implementing SMS/MMS Marketing.
