One of the public views in Zoho CRM Contact module is "Unread Contacts". What is it? I tried googling, checking with Zia, searching in the documentation, and here in the forum. A mystery, no definition at all, yet it is a view created by Zoho, and supposedly requires a definition somewhere...
One might think it has something to do with email subscription (it's listed right under "Unsubscribed Contacts") but lots of "unread" contacts don't even have an email address and they weren't sent any emails.
