You can think of emails like road signs along a customer's journey. There's all kinds of signs along the road. Some are simply reminders to ensure continuity. Others are rules. Most are directional: where to go, what to do, where to exit and change track. Automating emails helps provide a map for your customers to guide them through the different avenues they can or should navigate. There's no reason to waste time doing this manually. One such road is the order confirmation email. Here's an interesting list of different ways to handle such confirmations, so your customers don't miss the exit and crash in your customer service with unnecessary complaints.
