Determining if the customer needs have changed is a potential benefit of revisiting dead opportunities.

Revisiting dead opportunities can help to identify if their situation has changed, if their pain points have increased, or if they are more open to considering the product again.References:https://www.salesforce.com/resources/articles/lead-generation/#lead-generation-strategies
