Have you seen the new A/B testing module that's coming in the fall 14 release? It looks awesome! And coincidentally, there will be a Testing Strategy Facilitated discussion coming out on December 1st, 2014. The Testing Strategy session will give you valuable insight on where to start with testing, or if you already have a testing strategy in place, point out areas you might not be considering.
With this new testing option, Will you spend more time testing emails and campaigns? How will this affect your marketing strategy?
