I just want to confirm that the only way to push account name to Marketo is via a custom field-- is this right?
No, you can push account name from SFDC 'to' Marketo. Are you sure you don't mean "push account name 'from' Marketo"?

Maybe I'm confused -- I don't see any fields on the contact record that is 'account name'. Basically I want to create a smartlist that suppresses the account = LiveIntent.
Thanks, I use company name. However, the company name was not consistent with the account name in SFDC. I've found a work around.
