Movable Ink has always prided itself on providing marketers with a way to deliver highly customized emails, but today the company decided to take that one step further. It announced an SDK that enables developers to build custom applets to add their own unique information to any email.

The company has always seen itself as a platform on which marketers can build these highly customized email marketing campaigns, says Bridget Bidlack SVP of product at Moveable Ink.
