I have just under 55,000 contacts in the Zoho CRM. Most of them are being managed by the sales team. I have a subset of about 10,000 to whom I want to be actively sending marketing emails using Zoho Campaigns. I used to be able to set up my sync so only the contacts that met a certain criteria would be synced with Campaigns. Now all of them sync meaning all of them are applied against my Campaigns quota. I only have an option to mark ALL contacts as marketing or ALL as non-marketing. How does that make sense?

(1) Why would I want my non-marketing contacts in Campaigns to begin with? Why am I being forced to upgrade to add to my Campaigns quota which I don't need?

(2) How do I only mark the contacts I need as marketing ones? Right now it looks like it's an all or nothing for the entire module.
