What is the difference between SMS and MMS?

The main difference is the type of content you can send via the two messaging tools.

MMS (Multimedia Messaging Service)

• MMS is an enhanced version of SMS that supports multimedia content along with plain text.

• You can send images, videos, audio, GIFs, and text together.

• Maximum message size is 5 MB, including up to 1600 characters of text.

• MMS messages tend to have higher engagement rates (8% or more) and often result in better conversions.

SMS (Short Message Service)

• SMS is plain text only, but you can include links and other details in the text.

• Text length is limited to 160 characters.

• Messages longer than 160 characters are charged as multiple messages.

• In the US and Canada, messages over 500 characters are better sent as MMS for higher engagement and cost efficiency.
