Add an attachment to an email
When you use iCloud Mail, you can attach one or more files, such as a photo or a Pages document, to an email message.
Add an attachment
While writing a new email message, click the Attach button at the top of the message window.
Select the files you want to attach, then click the Choose button to begin uploading the files.
To select several adjacent files, click the first one, then Shift-click the last one. To select multiple nonadjacent files, Command-click them on a Mac or Control-click them on a Windows computer.
When the upload is complete, the attached files are listed above the message you’re writing.
To attach more files, repeat steps 1 and 2.
You can also simply drag files into your message. If you use Internet Explorer 9, see the Apple Support article Windows browser plug-ins, extensions, and add-ons.
Delete an attachment
In the Mail Message window, click the Delete icon next to the attachment’s filename.
For information about including original attachments in a reply, see Reply to or forward an email.
Important: An iCloud Mail message can’t exceed 20 megabytes (MB), including attachments. If you use an email app (instead of a browser), a message smaller than 20 MB might still be undeliverable. Your Internet service provider (ISP) may also have message size limitations. If a message is returned to you because it exceeds the maximum size, send the contents of your message in multiple email messages, or use compression software, such as the Compress feature in OS X, to make your attachments as small as possible.
