Email is apparently a hot investment right now. Email creation platform Stensul just raised a $16 million Series B, bringing total funding to $23 million. It seems odd that there’s a market for a stand-alone email builder, but, apparently, there are enough enterprise marketers wanting a best-of-breed solution to keep Stensul growing.

CDP mParticle is being acquired by ecommerce platform Rokt for a price of $300 million.  It’s the third acquisition of a leading independent CDP in a little over one month, following Uniphore’s purchase of ActionIQ and Contentstack’s purchase of Lytics. All three buyers offer some type of customer-facing technology; apparently they’ve decided that adding real-time profiles from CDP will give them a competitive edge.  (See this blog post for more analysis.)
