I am in the process of putting a responsive email campaign together and to achieve the design I want I need to be able to hide certain content from mobile clients and other content from desktop clients. While I have been able to hide desktop content from the mobile version (checked in Litmus and this is working consistently) I am running into problems hiding the mobile content from the desktop version, namely in Outlook and Gmail (the code I'm using works in a web browser and across clients on Apple devices such as the iPad and Outlook 2011).

There are thousands of articles out there about hiding mobile content; however, that's not the problem I'm experiencing - it's hiding content in desktop clients - and I've been unable to find a reliable blog post/article about this. Has anyone run into this problem before, or have any ideas how I can resolve this?

Look forward to receiving your comments!
