Email services all have their maximum attachment file size limit. If you attach a file of over 25 MB on Gmail, you'll be prompted to upload it to Google Drive and send the link to that file. Also, when you try to upload large files on the Apple Mail app or iCloud Mail, it gives you the prompt to send them via Mail Drop.
Mail Drop is a convenient feature available on both iPhone and Mac that allows you to send large files via email without worrying about attachment size limits. With Mail Drop, you can easily send large file attachments up to 5 GB to anyone via email. You do not need any installation or third-party configuration for this, as the Mail Drop feature is built into the Mail app on your Apple device.
In this guide, we will walk you through how to use Mail Drop on your iPhone or Mac.
