Text messaging has evolved a lot since the first one was sent 30 years ago. And MMS messaging has been a significant advancement in this domain, allowing users to send multimedia content like images, videos, and audio clips alongside text. But what exactly sets MMS texting apart from its predecessor, SMS? Do you know the difference? 

MMS and SMS are texting technologies that are quite similar at first glance. But they have some key differences that set them apart. Here we will define what MMS is, we’ll compare the two, detail the ways MMS messaging can support your business goals, and show you some examples of popular use cases. 

What is MMS messaging?

MMS is an abbreviation for Multimedia Messaging Service. As you may have guessed from the word “multimedia,” MMS messages are capable of incorporating images, video, and audio files. That includes all of the texts we send or receive that contain emojis and website links.

And considering that 90% of people open a text message within three minutes of receiving it, this media-rich form of communication creates great opportunities for businesses to reach and engage both existing and potential customers.

SMS and MMS messages offer different capabilities, depending on your business’ needs. Let’s dive into some of the similarities and differences of these two messaging channels.  

SMS vs MMS texting: Pros and cons

SMS is the common acronym for Short Message Service. It’s the most widely used (and one of the oldest) texting technologies in the world and is limited to just text.  

SMS and MMS have different features and reach that can enhance messaging between a brand and its customers. When used together, they can enhance a brand’s reach and engagement.

What’s the difference between MMS vs SMS messages?

The biggest difference between MMS vs SMS is that MMS allows you to include rich media files such as images, GIFs, and videos. MMS can send up to 500 KB of data (up to 1,600 characters) and up to 30 seconds of video or audio. Depending on your messaging provider, MMS messages typically cost more to send than SMS messages.

SMS messages are restricted to text (which includes links) and are further limited to just 160 characters. Because of their simplicity, SMS are generally cheaper to send and more widely available than MMS. Rates for sending bulk messages of either type vary by provider, as do capabilities and rates for sending MMS and SMS messages internationally. 

For marketing teams, MMS marketing is frequently used by businesses to increase engagement and boost sign-ups with multimedia content. Meanwhile, SMS marketing is a more affordable and scalable option for businesses with a wide or global reach.

How are MMS and SMS similar?

MMS and SMS do have some things in common, which leads many people to mistakenly use the acronyms interchangeably. 

They were built using the same base technology – MMS was initially created so SMS users could send multimedia files. And both MMS and SMS are delivered over a cellular network, which means recipients need a mobile device with a text messaging plan to receive them. 

SMS vs MMS: What about price?

Generally, MMS messages will cost more to send than SMS messages due to the larger amounts of data being transmitted. However, specifics will depend on your messaging provider. 

So when deciding on whether to use MMS messaging, you have to weigh the benefits against the costs. MMS messaging usually has higher engagement and opt-in rates than SMS, which could result in more click-throughs, sales, and revenue.  

Will that be enough to justify the higher costs? You’ll have to try it and study your data to know for sure.

SMS and MMS messaging vs. iMessage, WhatsApp, and other OTT channels

Some people may confuse SMS, MMS, iMessage, WhatsApp, and other channels because they all involve mobile messaging, but each channel is actually quite different! 

A key difference between SMS and MMS and other channels is that both SMS and MMS rely on a mobile network infrastructure, meaning that a user can receive messages on their mobile devices without a data plan. 

Meanwhile, Over-The-Top (OTT) messaging services like WhatsApp and iMessage (via Apple Messages for Business) rely on a cellular network connection for communication. These channels offer feature-rich messaging experiences like voice and video calling, group messaging, buttons, product catalogues, gifs, and other multimedia sharing that aren’t readily available with SMS or MMS. 

SMS and MMS reach 100% of users with a cell phone, while these OTT messaging services have a more limited reach: 

  • iMessage is available on iOS and allows a user to communicate with others if it detects the recipient’s phone number is associated with an iPhone. 
  • Messaging apps like WhatsApp and Facebook Messenger are available on both iOS and Android, and require a user to download an application to use them.  

Another difference between these services is the charges associated with them. SMS and MMS often incur charges per message sent or received. OTT channels on the other hand need an internet connection, making them more cost-effective.

5 MMS messaging tips

Research shows the engagement rate for text messages is 20 times higher than for emails, making MMS messaging a powerful tool for connecting with customers. Our 2024 survey of several hundred U.S. consumers also revealed that that they want to hear about promotions as often as they’re available, making mobile communication a fast, easy, and effective way to build customer loyalty.

Both SMS and MMS allow you to reach customers instantly on the devices that are probably already in their hands. Of course, MMS specifically offers some advantages worth considering depending on the campaign or marketing strategy you plan to use.  

From higher open rates to personalized experiences that maximize conversions and sales, there are many benefits of MMS messaging. Here are a few tips to make your messages as effective as possible.

1. Make messages hard to forget

Images add color and depth to the messaging you share with customers. The option to use images, videos, and GIFs can make your MMS message more visually exciting compared to a simple SMS text.  

In fact, scientists have found that when people hear information, they will most likely only retain about 10% of that information three days later. But when a relevant image is paired with that same messaging, recipients remembered 65% of the information after three days. 

2. Build relationships that last

SMS texts are limited to 160 characters, which can potentially create challenges for developing a message that actually connects with your audience. MMS messages provide an opportunity to craft more detailed messages of up to 5,000 characters. And adding images, videos, or audio files gives you even greater capacity to inform and engage.

Support for two-way messaging means MMS isn’t simply the equivalent of a personalized pocket billboard – it can help you reduce friction in the customer experience and improve overall customer satisfaction.  

Say you text picture proof of a delivery to a customer and they don’t recognize the location. They can immediately text back to tell the driver it looks like the wrong address. The driver then corrects the error while he’s nearby. Problem avoided and your company earned the trust of a now fiercely loyal customer.

3. Subject them to all the feels

MMS messages can also include subject lines, which not only creates a unique opportunity to spark an emotional connection with the consumer but also makes them more likely to open your text. 

Getting the subject line right can definitely drive higher MMS open rates, so make sure you’re applying best practices when crafting subject lines for text messages. Higher open rates for the win! 

4. Personalize all the things

Google’s data scientists report that 90% of leading marketers say personalization is a major contributor to building a profitable business. MMS messaging gives you the ability to deliver even more engaging personalization via text message.

5. Rely on SMS for fallback

You may have a mobile number to text, but there’s no way to tell if the person’s device is MMS-enabled ahead of time.  

Don’t worry, if an MMS message can’t be delivered, they’ll still get an SMS fallback message. This fallback message has a dynamic URL to the original multimedia message you sent and ensures your communications are always received as you intended.

MMS messaging can be deployed to engage and inspire action in welcome or onboarding texts, new product promotions, Black Friday deals, rewards notifications, abandoned cart reminders, and more. 

Sending appointment reminders or delivery confirmations

Because MMS can include visual elements like location images, it can be a helpful tool to provide visual confirmation of appointment times or deliveries. 

Plus, MMS allows for a longer character limit than SMS. That means you can provide more detailed information about the appointment, like a map, additional instructions, or special requirements for your customer to remember. 

Personalized offers

Relationships between brands and consumers don’t end with a purchase. 

With MMS, you can send high-quality product images, promotional videos, or interactive elements to showcase products or services that you know are super relevant to your target audience.

Digital receipts and payment confirmations

Brands can use MMS to send payment confirmations that include important details like any reference, account, or confirmation numbers. This can be reassuring to a customer to help them keep track of payments and have a record for future reference. 

Plus, digital text receipts eliminate the need for a customer to have a physical copy, making their life a little easier if they need to get in contact with you about something they’ve purchased!
