More tools are emerging these days that let consumers organize multiple email accounts into one client. A recent example is called Inky. It's an email desktop client that lets users access their Hotmail, Gmail, Yahoo and Outlook accounts within one desktop application.

So for example, they can aggregate all content from daily deal providers into one view and all subscription newsletters into another view.

SMS spam is on the rise and many of these fraudulent messages have taken a page from email spam messages, trying to coax users with free offers and too-good-to-be true promises.

Yahoo is expiring inactive email addresses and giving away these lapsed names to new people, which could pose a security risk to users. eBay and other ecommerce retailers let users to recover their User IDs if they share their email address. Ina Steiner, Editor of EcommerceBytes points out "users who signed up to eBay (or other etail sites) with Yahoo email address could find third-parties hijacking their accounts if they haven't signed in to their Yahoo accounts lately. And since many people use the same password across multiple services, this leaves them vulnerable to multiple account takeovers."

A bipartisan group of representatives are leading the push to pass the Email Privacy Act, which would give U.S. citizens the right to email privacy. The bill, which is being spearheaded by Kansas Republican Kevin Yoder, Georgia Republican Tom Graves, and Colorado Democrat Jared Polis, already has 94 co-sponsors. If passed, it would modernize the Electronic Communications Privacy Act (ECPA), the 1986 law that governs modern day email privacy rules. Under ECPA, government agencies such as the IRS, DHS, and SEC, can access a citizen's emails older than 180 days without obtaining a search warrant.
