What is categorized as 'other' in the email insights report for device type?

[Chelsey_Davis]

Hello,

I'm trying to break down opens by device type. I have desktop, mobile, tablet, and then there's the wonderful 'other,' which seems to make up a good chunk of my opens. Does anyone know what is categorized as other?

Any guidance would be much appreciated!

Thanks, Chelsey

Not exactly sure, but it seems to group the non majors into Others. is it a large percentage for you?

It is larger than I'd like it to be. Large enough for stakeholders to question what fell into it...

Do you have ideas on what the non majors would be?
