Have a tool to find duplicate emails
I would love a way to find duplicate emails in my mailboxes. I'm trying to reduce the size of my email archive in order to free up space on my MacBook Pro, and I'm pretty sure I've got a lot of accidentally duplicated emails. I'm looking for a tool that would find duplicates based on email subject, content, sender, size, date, etc. Something like this exists for Apple Mail (see https://en.freedownloadmanager.org/Mac-OS/Remove-Duplicate-Messages-FREE.html) but not for AirMail.
