a quick question that is not clear to me after reading quite some posts about DMARC: does it require a dedicated IP or can it be setup also on an instance that uses Marketo shared pool of IP's ?
DMARC can certainly be set up for the domain example.com without a dedicated Marketo IP (or, more precisely, even if you're using a non-branded *.mktomail.com sender domain, as you are with a shared Marketo IPs).
You won't achieve SPF alignment for Marketo emails (which is more than fine) but you'll have DKIM alignment.
