Attachments.me allows you to easily search and sort through your email attachments, and upload and share your attachments from Gmail to your various cloud services such as Box, Dropbox, and more. What's more, with customizable filing rules you can actually automate the procedure. The attachments search and automatic filing are neat features, but do note that there are limits to the free account. These include a 100MB file limit, two automatic filing rules, attachment search for one month's worth of attachments, and 75 attachments moved per month.
Verdict: Attachments.me lets you easily integrate your email attachments with your cloud storage, making it easy to archive and backup important attachments.
