The automatic workflow that can be created to prevent the unassigned prospects from getting assigned is to create an automation rule based on the prospects’ time to adjust their score to 0 if they haven’t been active in 60 days. An automation rule is a rule that runs continuously in the background and matches prospects based on the criteria you set. You can use an automation rule to perform actions on the matched prospects, such as adding them to a list, assigning them to a user, or changing their field values. However, an automation rule can only match a prospect once in its lifetime, even if the prospect meets the criteria again later. This prevents duplicate or conflicting actions from being applied to the same prospect1. Therefore, an automation rule is ideal for creating a workflow that resets the score of the unassigned prospects who have been inactive for 60 days, and prevents them from getting assigned by another automation rule that assigns prospects based on their score. To create an automation rule, you need to specify the criteria and the actions that you want to execute. For example, you can create an automation rule that matches prospects who have not been assigned to a user, have not had any activity in the last 60 days, and have a score greater than 0, and then use the action Adjust Score to set their score to 0.
