2013 is the year of the mobile device:
Mobile Takes an Increasing Share of Email Opens – eMarketer: “In May 2013, research from marketing solutions provider Harland Clarke Digital found that consumers primarily in the US used the desktop to open 55.2% of business-to-consumer (B2C) and business-to-business (B2B) marketing emails. The smartphone took one-quarter of email opens. And when adding in the tablet, mobile’s share of exclusive email opens rose to nearly one-third.”
Email marketing is still an indispensable tool for many businesses and is something you should integrate into your campaigns early.
