With MMS, individuals can easily add all sorts of rich media right inside the messages, including gifs, images, audio and video files. You can even write about 1,600 characters in one single message. This is not possible in the case of SMS that only allows regular texts to up to 160 characters, particularly in the US.
MMS Marketing is also referred to as video messaging, multimedia messaging, and video massaging. But what you call. This does not matter as much as what you can significantly do with it.
