How to Add Custom Parameters in Litmus Tracking Code Manager
Our Marketo and Litmus is in sync. We are using Litmus tracking codes for some additional tracking of our emails send through Marketo. We want to use same tracking code for a particular Marketo program having multiple email sent. So, we want to use custom parameters to differentiate the individual emails. What parameter or field could we use from Marketo under that and in what format do we need to put it there. Also, could we add multiple parameters and how do we separate them (i.e. using a + or & sign). Attached is the image for reference.

Thanks
