Add a message from Apple Mail as attachment


Hi all,
I’m pretty new to Airtable.
Currently I’m creating some sort of simple CRM application in which I can store (mainly) open and closed projects and opportunities. I would like to have all email conversation associated with a specific project or opportunity to be linked to it.
I’m on a Mac, and my main email app is Apple Mail. Is it possible to add (as in drag & drop) the conversations as attachments, or is there some other way.
