ExtractEmails Pro

Extract Emails Pro is a simple and cool app that allows you to extract all e-mails inside files recursively in any folder and export them to a CSV file that can be opened in Numbers, Excel, or Libreoffice.

You choose the folder to be analysed and all the files will be searched for e-mails. A list with all the e-mails is created and can be previewed and exported to a table file. You can, for example, search and retrieve all e-mails inside your Mail folder (~/Library/Mail/V2).
