A lot of companies want to have more leads in Marketo than SFDC and only push MQLs into SFDC.
But this creates a problem when reps enter lead/contacts directly into SFDC. Even if they check SFDC, and there is dupe blocker installed, they are still unable to see the existing lead (because it's in Marketo) and they go ahead and create a new lead/contact - thereby creating a duplicate.
How do you guys deal with this?
One suggestion is to sync all Marketo leads with SFDC - 1 to 1 - that way whenever you search for existing leads in SFDC, you're searching the entire marketing database. But this isn't ideal because there are truly instanses where it's not ideal to have the entire database in both systems.
