Send to Dropbox is a free service that allows you and others to send email attachments directly to your Dropbox account. To use Send to Dropbox you have to connect it to your Dropbox account. Once connected Send to Dropbox will provide a unique email address that you can send files to to be added to your Dropbox folders. If you give the email address to others they can add files to your Dropbox folder too.
Applications for Education
Send to Dropbox is similar to File Stork and Drop It To Me which I have previously reviewed. Like those services Send to Dropbox could be a great way to have students turn in their assignments electronically without flooding your email account with attachments.
