iCloud: Download email attachments from Mail on iCloud.com
A message that contains an attachment has a paper clip icon to the right of the sender’s name in the message list.
If you receive an email with an attachment (a file), you can open the file after downloading it to your computer. If the attachment is a Pages, Numbers, or Keynote document, you can download it or just open it in Pages, Numbers, or Keynote for iCloud. If the attachment is a vCard file, which has a filename ending with .vcf, you can just add the contact information it contains to your contacts.
Large attachments can be delivered by Mail Drop if the sender has turned it on and is using Mail on iCloud.com. You don’t need to have Mail Drop turned on to receive these attachments. You can download attachments from Mail Drop for 30 days after they’re sent.
If you want to use Mail Drop to send your own attachments, see “Turn on Mail Drop for large attachments” in Add an email attachment in Mail on iCloud.com.
In Mail on iCloud.com, open a message that contains an attachment.
If you don’t see the attached files listed above the message body, click More (on the far right).
Click the file you want to download to your computer, then locate and open the attachment.
The file is downloaded to the location specified in your web browser’s settings. With Safari on a Mac, the default location is your Downloads folder.
Open Pages, Numbers, and Keynote attachments
In Mail on iCloud.com, open a message that contains an attached Pages, Numbers, or Keynote document.
At the bottom of the message content, click Open in [App] to the right of the attachment icon.
The document opens in the document editor window of Pages, Numbers, or Keynote for iCloud.
If you want to open the attached document in the Pages, Numbers, or Keynote app on your Mac, download the attachment, then open the downloaded file.
Add an attached vCard to your contacts
In Mail on iCloud.com, open a message that contains a vCard attachment, which has a filename ending with .vcf.
If you don’t see the attached file listed above the message body, click More (on the far right).
Click the vCard (.vcf) file whose contact information you want to add, then click Add to Contacts.
If you can’t open an attachment, it might have been created using an app you don’t have on your computer. Ask the sender to resend the file in a format compatible with an app you have.
