How to find leads deleted from SFDC, but not deleted from MKTO?

[Anonymous]

Can someone please suggest SmartList criteria to find leads that were deleted from SFDC, but not deleted from MKTO?  The challenge is that the MKTO field shows the SFDC Type = Lead and Marketo SFDC ID has a value in it.  However, when you try to find that Lead in SFDC, it doesn't exist.  I want to remove those leads from MKTO.

Thanks in advance,

Dani

You can run a smartlist and apply the filter "SFDC is Deleted" is TRUE. This used to be a system smart list but it looks like you need to build it yourself now.
