I'm Jason Parker for CNet and today I'm gonna be taking a closer look at the new mail app.
Mail markup is a great new feature that lets you comment on photos and documents before sending them to a recipient.
When you add an attachment, a little arrow appears in the upper right where you can choose markup.
Once in the markup interface, you can use lines, graphics, arrows and other graphics to call attention to either photos or documents.
You can then add text to clear up any confusion.
And then send the email straight away.
The markup features also let you sign your name to a document, just click the icon that looks like a signature.
Then you can sign your name using the trackpad.
Or show a picture of your signature for the Mac camera to scan.
From there you can move it into place to sign your document.
The other big new feature in mail is the ability to send large files via mail drop.
Now when you try to attach a large file under 5 gigabytes, mail will ask you if you would like to use mail drop.
It then uploads it to iCloud drive, bypassing any limits put on attachments by internet service providers.
Even if your recipient is not an Apple user, Maildrop will store it within iCloud, then send a link for them to download it.
The new mail out comes with a free upgrade to Yosemite at the Mac App Store and it's available today.

Thanks for watching.
