Email

Three of the most common key performance indicators (KPIs) for email are still open rate, clickthrough rate and click-to-open rate. But figures from email service and marketing technology providers show variations in those KPIs in North America depending on a variety of factors, including geography, industry, seasonality and the types of email messages being sent.

eMarketer principal analysts Nicole Perrin and Jillian Ryan explain how email is changing in usage, measurement and personalization. They also discuss Netflix Q3 earnings, how companies struggle to top Google's search results and what matters to consumers when buying a new smartphone.

Email is still at the center of marketers’ digital programs. No surprise there; it offers several benefits: It’s an owned communications channel, it’s permissioned—meaning consumers have opted in and indicated interest—and it’s a traditional marketing channel that most marketers are thoroughly experienced with.

When retailer Cynthia Rowley saw that mobile comprised roughly 72% of its traffic, the company decided to launch a text message channel, giving consumers another communication channel beyond email.
