What is Zoho Marketing Plus?

What is Zoho Marketing Plus?

As if there wasn't enough confusion with SalesIQ, CRM, Campaigns and Marketing Automation, now we have Marketing Plus too.

Can somebody from Zoho please give us a comparative list of features that are in Marketing Plus compared to what's in Marketing Automation?

And please make it a list of specific features, not "A is for this type of user, B is for that type of user."

Thanks

Steve
