Couchdrop has developed a simple way to send email attachments directly into cloud storage folders within likes of Dropbox, Box, GoogleDrive, AWS S3, Azure Files etc.
Head to your Virtual File Storage within Couchdrop and press the three dots to the right of the folder you would like to have your attachments go into. Select Properties
Within Properties scroll down until you find Email Upload and tick the Enabled checkbox. While you are here, copy the email by double clicking the email address and copy it. At this point we would recommend creating an email alias for this email address.
All you have to do now, is email your attachments to the email address with no subject line required and you will find your attachments as files within your chosen folder.
