Opening .eml Files on a Mac

More and more I’m getting emails from clients with .eml attachments. These are generally email messages created by Microsoft Outlook and may contain their own attachments (files or images etc).

The issue for me is that I don’t use Outlook…but I still need to find a way to open them, ideally a way that includes accessing the original attachments.

Luckily there are a several options, including (first download the eml file):

  • If you have Apple Mail setup, just double click the .eml to open the original email. This also gives you access to the attachments
  • Open in Preview (select the file and hit the space bar). This is ok but only for the text part of the email, no attachments
  • Download and rename the eml file it as .mht (or .mhtml) then open it in any modern browser. This is because it’s just a MIME HTML file. This is ok but only for the text part of the email, no attachments
  • Install dedicated software like this Chrome extension

Clearly using Apple Mail is the winner, for me this mean setting it up with an account I rarely use…just so I could open it.
