What is tier 0 customer support?
Reflecting the importance of providing excellent self-service to manage rapid growth and satisfy customers, you might want to launch tier 0. What is tier 0? It’s the self-service tier; the support available to customers that does not require directly interacting with a customer advocate. This includes the knowledge base available in an online help center, the product training that is available to customers, as well as assistance that is available in the product’s user interface.
