This email from hardware retailer B&amp;Q caused a bit of a stir in the email design community last week.  Its stand-out feature is an interactive content slider that allows to tap through the various offers B&amp;Q have. This cool functionality also works on some desktops and mobile too (next two pins).  The carousel only functions on newer email clients, so this version is the fallback for clients such as Outlook. Look at the next two pins for the full functionality.  Top marks!
