Segmenting by device type can make a big difference, especially if your offer works better on one type of device. Some offers or landing pages look better and load faster on mobile, while others may perform best on desktop. If you know which device a person is using, you can send messages that match their experience better. For example, mobile users might respond better to shorter texts and simple images. Desktop users may handle longer messages or offers with more steps. Sending the right message to the right device can help improve both clicks and conversions. Has anyone here tried this kind of split before to help their campaigns?
