The Omnichannel Argument
The data consistently shows that customers don't choose one channel - they use whichever is most convenient at the moment. The winning strategy is not to pick one channel but to unify all channels into a single inbox so agents have full context regardless of where the conversation started.
IdeaSprout Customer Support does exactly this - one dashboard, all channels, full thread history.
