You do not need a ChannelReply or helpdesk account to use CR Feedback. It's a separate product with a separate subscription, and works all on its own.
If you have both ChannelReply and CR Feedback, you can manage both in your ChannelReply account. No juggling multiple logins or wasting time redoing eBay or Amazon integrations! Both products are built to work together just as easily as they work alone.
Bonus: If you use Zendesk, Freshdesk, Re:amaze, Zoho Desk, Kustomer, or Onsite Support with ChannelReply, you get extra features! You can send any CR Feedback review request from Amazon support tickets, or even cancel your scheduled requests.
