Sync is not bi-directional by default and can be edited. Status sync settings depend on the user configuration set in Extension Settings. Mailshake Connect handles data in all data centers except CN. Once synced with Mailshake campaigns, Leads can be viewed and managed in the Mailshake Pro Campaigns module. Sync is real-time with Mailshake and occurrence cannot be edited. Extension supports selecting Leads and syncing with multiple campaigns in Mailshake.
