Abstract: Customer type detection and customization and/or configuration of services based on detected customer type is provided in an online service environment. In some examples, a small business customer signing up for an email account or similar (e.g., more complex services such as a productivity suite) way be detected as a small business based on a choice of their email alias, domain name, signature, and other factors. A type of business may also be detected/inferred. Based on the detection inference, the services such as initial teaching user experiences, configuration of services, and other customizations may be automatically provided or suggested to the customer. Subsequently, usage may be monitored and further services and/or configurations (configuration changes) may be suggested based on additionally gathered information and changes in usage.
