Searching for emails is a common part of an external pentest and could also be useful for internal pentest, depending on the perimeter and Red Team. Find emails could help to get more information about the target's mail servers. If a user's emails credentials have been compromised it could help to find others credentials for this user or to use Social Engineering attacks, such as phishing.


Here is a workflow divided in 3 parts, the first part is about finding emails, the second one to know if the email leaked in a data breach and the third one to find the data breach. This workflow is still in process and is not exhaustive.
