Hey all, Ive read this rundown on Android mail apps while Ive been trying to understand why my background images dont render on the Android 6 and 7 OS in Litmus (but do when I test to my own test devices). I put this down down to the difference in mail client type as the article suggests. Does anyone know or have data on the top 5-10 mail clients (besides gmail) for Android? Im trying to nail down what client support I should prioritize. Can't seem to find much on this online.

Thanks!
