Smartphone usage is sky-rocketing, and with it, so is the number of people that are reading email on a mobile device.
According to Litmus, 43% of email is now opened on a mobile device. That number is up 138% from 2010, and I think it’s a pretty safe bet that it’s going to continue to grow.
This means that you need to be creating emails that are mobile friendly. A mobile-friendly email is an email that displays optimally between a desktop/laptop and a mobile device, ensuring that it will look great regardless of where your customers and prospects read it.
