What is MMS?

Multimedia Messaging Service (MMS) is a standard in mobile messaging where you can include text, sound, images, animated GIFs, and video. This provides a more interactive and eye catching experience for the user and the visual content displays and plays within the recipients SMS application standing out from all other SMS (text only) content and messages.

How does MMS display?

Unlike any standard text based message, an MMS displays the creative in the SMS app on a users phone. This has the distinct benefit of being eye-catching, and standing out from all other text only messages.

In addition to that, an MMS 'Previews' on a users phone, again standing out from any text only based messages.

How can users reply to MMS?

The Sender ID will be a Virtual Mobile Number we assign you. It will be able to send and receive SMS as well as send out MMS. That means when you send out MMS, then your audience can chose to reply via SMS.

We recommend only to use vertical (portrait) or square images as nearly all modern device screens are vertically aligned.

Who does the creative?

You are required to produce your own creative. Your creative must be one of the sizes and formats listed below.

What file types are accepted?

The following are the most widely used file formats that we recommend to use for your MMS creative. These have historically shown the highest level of successful deliveries:

• .gif (including animated - infinite loops and less frames are recommended for best results)
• .jpg or .jpeg
• .png
• .mp3
• .mp4
• .mpeg4
• .mov

NB: When using Photoshop etc for creative files, please remember to remove all meta data from you final creative.

Tool to remove Meta Data: ImageOptim

What is the maximum file size?

Files must not exceed 450kb (for all files combined) per MMS. You can try free tools such as https://ezgif.com/

What media can I send?

Static Images:

We recommend:

• 480px by 480px
• 640px by 640px

Other sizes you can experiment with:

• 480px by 720px
• 640px by 1138px
• 1080px by 1920px - an image that is 640px by 1138px, or 1080px by 1920px, both have the same aspect ratio of 9:16. The images will be sized to meet the width of most screens.

Animated GIF:

We recommend either 480px by 720px (tall), 480px by 640px (tall), 640px by 640px (square) or 480px by 480px (square) sizes depending on the amount of animation.
