As the year went on, we continued to build on these features, releasing powerful updates to make them work harder for you \u2013 based directly on your feedback. Our latest updates to Series<\/a>, Banners<\/a>, Articles<\/a>, and Resolution Bot<\/a>, to name but a few, empower you to streamline your messaging workflows, improve team collaboration, and most importantly, create better experiences to meet your customers\u2019 evolving needs.<\/p>\n Want to see these features in action? Check out our latest Built for you webinar<\/a>.<\/em><\/p>\n We released our visual campaign builder, Series<\/a>, last year to empower you to design the most effective multichannel messaging campaigns. Since its launch, we\u2019ve been working tirelessly behind the scenes to make the product even more powerful, releasing several new features that make Series that much more effective at helping you reach your customers in the right place, at the right time \u2013 and with the right message.<\/p>\n Knowing which messages to send \u2013 and when \u2013 can be tricky. To help you narrow down what’s resonating most with your customers, we’ve added split testing to Series<\/a> so you can test up to five different message types, message content, CTAs, timing, and more. When you accrue enough data to determine the most effective path, you can select the winning variant and direct any new users that enter that Series flow to follow that path.<\/p>\n With so many campaigns running simultaneously, it can be difficult to keep track of everything that\u2019s happening. We\u2019ve added annotations to Series<\/a> so you can leave notes for yourself or collaborate with teammates directly within the campaign builder to ensure everyone’s on the same page.<\/p>\nEfficiently scale your messaging with new additions to Series<\/h2>\n
