Since my Apple Mail is starting to crash every few days since the latest Mavericks updates and is getting really slow in opening old and getting new mail (although I run on SSD), I am looking for another way to archive old emails and still have the same easy access with all search capabilities. This where Evernote comes in! Googling a bit I found this AppleScript: Apple Mail to Evernote.
The script works perfectly under Mavericks and I added some code to get the date/time in the title of the note. A screenshot of how an email in Evernote looks when my modified version of the script has done its job:
What you'll miss though is the grouping of the 'Conversation'-view which you have in Apple Mail.
So you can download the original or download my version.
Thanks to Veritrope for this very useful script!
