MMS messaging best practice (plus 10 templates)

MMS, better known as multimedia messaging service, is pretty much SMS on visual steroids. Perfect for marketing campaigns, MMS allows you to add any kind of multimedia content to your messages. Unlike SMS (short messaging service), MMS also increases the amount of text you can send in a single message. In addition, it can also elevate customer engagement and responsiveness to new heights over SMS. 

While this is all great in theory, it’s even better when you see it used in real life. Now that you’ve got the fundamentals down pat (or if you don’t, definitely have a gander at our Beginners Guide to MMS), let’s look at MMS in practice.

Best practice and design tips for writing MMS messages

Here are our top tips for getting the most out of your MMS broadcasts:

  • Subject line: Use this wisely!

It appears as a short, bolded headline of 64 characters, and will be the first thing your recipient will read, so make it count. Make sure you use this line to entice readers, pique curiosity or hit a slam dunk with a strong CTA.

TOP TIP: Need some inspiration? Jump into your email inbox and look at what subject lines that draw you to open them.

  • For images:
    • If you’re going to include image files, we recommend using JPG format. While PNGs are of higher quality, file sizes of images are restricted to 420kb.
    • The best image dimensions are 327 pixels (height) and 400 pixels (width).
    • Image resolution should be at around 72 pixels.
    • To help compress an image, while retaining the quality, use a free tool like TinyPNG or TinyJPG.
    • Try to make your image layout vertical as most mobile devices display vertically. However, a nice to have, not essential.
    • Try different sizes and layouts. If you’re promoting a car, use a horizontal banner. For a dress, vertical is the way to go. 
    • Check the text! Text on the image you mockup may look great on your computer screen but needs to still be readable on your mobile device.
    • AND we especially recommend you always send a test message to yourself.

  • For gifs:
    • Use .GIF format for animated images.
    • File size for GIF formats should be below 420b.
    • Be mindful that due to movement and compression, gifs will be of lesser quality than a static image. 
    • If you have a video you want to convert into a gif, use free tools such as EZgif.
  • For audio/video:
    • Remember it’s on average about 410kb of data, so if you’re sending an audio snippet, make sure it’s less than 410kb or around 30 seconds.
    • If you’re sending MMS videos, 
    • Audio formats: AAC, MP3, WAV
    • Video formats: AVI, 3GP, MP4, MPG

  • Body message: No longer are you restricted by 160 characters!

You now have almost 5000 to play with. BUT just because you have more, doesn’t mean you have to use alllll of it. 

Keep your body copy to less than 500 words for better, and easier readability. Remember most people are used to SMS marketing and SMS messages, not pages of text!

  • If you posed a question in your subject line, make sure to answer it here.
  • Use your body copy to fill out the details of your offer, event, promotion etc. 
  • Include a shortened link if there’s not enough room to include all the details.
  • Remember to add opt-outs to comply with your local laws and regulations.

How to get started with MMS

1. Pick the right messaging provider and partner.

It’s important that your choice of messaging provider, whether it’s MessageMedia or someone else, offers MMS and a variety of other SMS products and functions. Do your research thoroughly and figure out if they have everything you need.

RELATED: Read our blog on what you should look for when assessing a potential messaging provider.

At MessageMedia, you can trial out 25 messages – all for free when you sign up for an account. We can get you set up in just a few minutes.

3. Write a targeted message.

Make sure that you think about how to best position your product including the best subject line, body copy and what kind of media would best represent its value. Don’t forget our best practise tips for writing MMS above!

Take inspiration from our many use cases, and use their messaging if you’re unsure about your own.

4. Test your MMS on a work colleague, a friend, or family member. 

Ask them afterwards how fast they opened the message, and whether the messaging and image enticed them. Ask them if they weren’t enticed, what worked and what didn’t.

5. If you’re happy with the results, talk to your messaging provider.

Whether it’s us or a competitor, make sure you ask about what kind of plans, subscriptions or offers they can put together that would best work for your business and budget.
