How to Achieve the Best Media for Your MMS Campaign


Resizing and keeping your media at the correct scale is important for optimizing deliverability in ThruText. While some carriers can support larger files, others have limits that make it best to send messages with media under 750KB.


The Media Library restricts the maximum size for compressed media at 750KB, while allowing for uploaded media to be up to 10MB. However, for cases where you have additional, external resizing to do or have a file exceeding 10MB, this guide offers recommendations to help you resize media for best results.

Resizing Images using Preview for Macs

To resize images in Preview on a Mac, follow the directions on resizing images in Apple's Support guides. It is essential to select "Scale proportionally." By scaling proportionally, when you change the image's vertical or horizontal dimensions, the other value changes to maintain the proportions. Then, if you choose a size from the "Fit into" pop-up menu, the image's width or height may be smaller than the selected size to maintain the proportions.


Resizing images using Photos in Windows

To resize images using Photos in Windows, follow the directions in this Business Insider guide. Once the image is open in Photos, you can click the three vertical dots to access the "Resize" tool. By choosing the "Custom" option and selecting "Maintain aspect ratio," your image will automatically adjust when the height or the width is changed.


Other tools for images

Free tools like Krita, Image Resizer, or GIMP can be used. Alternatively, your organization may use a paid-for tool like Adobe Photoshop.
