Hey @Delaney_Childers! Unfortunately, it’s not currently possible to view all opens by device, only by campaign. However, I’ve passed your feedback on the the Product team to consider adding a solution to our roadmap.  

Have a lovely weekend :) 

Any updates on this?

This would benefit us in creating an optimized content focusing on mobile/desktop so we can target people better

Any updates? 

Seeing how cumbersome the editor is, at least give us the info who we are catering to! 
Having no options to have different paddings, alignments and image sizes for mobile vs. desktop is stupid. 

I would also be interested in having this kind of reporting.

Are we still not able to add a dashboard card for this type of information?

It would be useful to see which type of device is most popular among users overall rather than in each campaign. Our company has a few different brands that we use Klaviyo for, and it would be nice and easy to tell which device has the most average opens amongst each of our brands if this was included in the dashboard… I am curious to see if it is the same device type across all our brands.
