How to use Mail Drop to send large attachments up to 5GB in size with OS X Yosemite

The OS X Yosemite Mail app has a new feature called Mail Drop that lets you attach files as large as 5GB in size. Here’s how to use it.

With Mail Drop, you don’t have to be concerned with the email provider on the opposite end as Mail Drop works with all mail providers. Mac users will see files attached with Mail Drop as any other attachment, whereas other mail apps will show the Mail Drop attachment as a link in the mail, that they can click and start the download. Rather than attaching the file to the email message, Mail Drop uploads the file on iCloud.

To use Mail Drop just ensure you’re signed into iCloud. Here’s how you do that:

  • Click on the Apple menu in the menu bar, and open System Preferences. You could alternatively use Spotlight or Launchpad to open it.
  • Click on the iCloud icon, and sign in if you haven’t already.

You can now attach files up to 5GB without doing anything out of the way. Just drag and drop files into the Mail compose window, and the app handles everything for you. Large video files, PDFs, presentations, zip files, or any other type of file can be sent with Mail Drop.

I can see myself saving a lot of time not having to upload large files to Dropbox and paste links to them in mails with Mail Drop. What do you think about this feature? Let us in the comments below.

    i Dropped my file into an email message and hit send and now its just sitting in my out box not doing a thing. Now what? how do you send it or why isn’t it sending?

    • It’s likely uploading the file to iCloud. If it’s a large file, might take some time to complete the upload.

        It also depends on your internet connection, specifically your upload speed. Those 358mb need time to get to the server.

    Doesn’t work at all says the file attached is to big Apples’s own server said this. the file was only 358mb big thats a far cry from 5gb. lol

    Nice guide! But if you need to move anything larger than 5GB, I’d recommend Filemail. They have a very simple & clean web app that lets you send 30 GB to any e-mail for free and with no annoying ad-infested download pages. Hope that helps!
