Flows are tools that automate business processes by collecting data and performing actions in your org or an external system. Flows can be triggered by various events such as record creation, updates, or invocations from other processes or flows. Flows can also send email alerts as part of their actions. To send a notification when a record is deleted and by whom, and to maintain their own discovery information, an administrator can use a flow that runs when a record is deleted, queries the record owner’s email address and discovery information from another object or variable, and sends an email alert with those details.
