I would ideally like to have a US database and an EMEA database.
Thank you for the help!
I would take a look at Workspaces and Partitions, which is an add-on feature: Workspaces and Person Partitions - Marketo Docs - Product Docs
Even with lead partitions, ALL leads will still be part of the default workspace. Also, is this question to comply with the upcoming GDPR legislation?
