Salesforce Exam Service-Cloud-Consultant Topic 5 Question 56 Discussion

A recent review of customer satisfaction surveys revealed the support center does a poor job of upseting new products to customers. Customers report dissatisfaction when calling for troubleshooting, billing, enrollment, or similar issues and receiving a sales pitch. However, customers that have been upsold new products are two times more likely to remain a customer.

What is the recommended method to ensure upselling only occurs when customers are likely to be receptive to the offer?
