Mail Drop is a feature available on Apple devices that allows users to send large files through email. With Mail Drop, you can send attachments up to 5GB in size, which would otherwise be limited to the file size limits set by email providers. This feature is available on both iPhone and Mac devices and can be used to send all kinds of files like videos, images, and documents.

How to Use Mail Drop on iPhone:

1. Open the Mail app on your iPhone and create a new message.

2. Tap and hold the attachment icon which is represented as a paperclip.

3. From the menu that appears, select ‘Add Attachment’.

4. Select the file or document you wish to send, and tap ‘Share’.

5. Tap on Mail Drop from the list of options that appear and confirm if required.

6. The file will now be uploaded to iCloud and a link will be attached with your email.

How to Use Mail Drop on Mac:

1. Open the Mail app on your Mac and create a new message.

2. Drag the file or document you want to send from your desktop or Finder window and drop it into the message body.

3. If the file size exceeds the limit, you’ll receive a prompt asking if you want to use Mail Drop to send it.

4. Click on ‘Use Mail Drop’ and wait for the file to upload.

5. Once the file is uploaded, it will be replaced with a link in your email.

When the recipient receives your email, they’ll be able to download the file by clicking on the link. The file will be stored in iCloud for up to 30 days, after which it will be automatically deleted. If the recipient uses their Apple ID, they can download the file directly without any additional sign-ins or passwords.
