When you’re sending a file, you can add attachments in Gmail up to 25 MB—but what if you have larger files such as videos? Save these large files in Google Drive, then insert a link to the Drive or shared drive file in your email.
Note: If your recipients don’t have viewing permissions for the file, you can grant them access in Gmail before sending.
When you receive a file in Gmail, you can save a copy to Google Drive.
