Identify which channels you will use to respond to customer queries, including email, social media, live chat, or phone, and who will respond. Generally, customers expect a response within around 24 hours for email, a couple of hours for social media, and immediately through the phone. You can decide which combination of channels works best for you based on your resources and schedule. Managing customer expectations concerning the hours that customer service is manned and the turn-around time for responses is essential to ensuring customers are satisfied.
