You can attach one or more files to a message when you use Mail on iCloud.com. If you want to attach files that are too large to send in an email, you can use Mail Drop. It lets you upload attachments up to 5 GB and send a link or preview to your recipients. You can send these attachments from iCloud.com or from the Mail app on your iOS device (iOS 9.2 or later) or Mac (OS X 10.11 or later).
Recipients can download Mail Drop attachments for 30 days after they’re sent.
To Add an Attachment in iCloud Mail
- While writing a new message, click the Attach button at the top of the message window.
- Select the files you want to attach, then click the Choose or Open button to begin uploading the files.
If your attachments are too large to send in an email, you’re asked if you want to deliver the attachments using Mail Drop. If you agree and Mail Drop is turned on, the attachments are uploaded to iCloud. It may take some time for the upload to complete, depending on the size of the files.
- To attach more files, repeat steps 1 and 2.
You can also simply drag files into your message.
To Remove an attachment
In the Mail Message window, click the Remove icon next to the attachment’s filename.
You can only remove an attachment before you send the message.
How to Turn on Mail Drop for large attachments
For people want to use Mail Drop to deliver large attachments, make sure it’s selected in iCloud Mail preferences.
- Click the Action pop-up menu in the sidebar, then choose Preferences.
- Click Composing, then select “Use Mail Drop when sending large attachments.”
- Click Done.
For information about including original attachments in a reply, see Reply to or forward an email.
You can’t remove files already sent with Mail Drop. They expire after 30 days.
