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 device. 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, tap More (on the far right).
Tap the file you want to download to your device.
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, tap More (on the far right).
Tap the vCard (.vcf) file whose contact information you want to add, then tap 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.
