15% of E-mail is Viewed on a Mobile Device [infographic]
According to Litmus.com research, as of July 2011, 15% of all e-mail is viewed using a mobile device.
What’s also pretty neat is that the iPhone accounts for 10% of all email viewed. That’s virtually a parallel number to Hotmail and Yahoo! Mail, and more than double Gmail.

This is a great post. I just wanted to add if I may.
The way we use our mobile devices is changing with the technology that smart phones are built upon. Mobile internet browsing has increased and will continue to increase with the rapid sales of smart phones. As the number of smart phone users continues to increase so will the amount of local searches from a smart phone.
People are using their smart phones to do local searches to find businesses that are close by, like restaurants, lock smiths, bars, cafe’s, entertainment venues, etc. So with this increase in local searches it’s important for business to take care of there website and make it mobile optimized.
If a business has a user friendly version of there website to make the user experience easier it will increase there sales. People that use a cellular phone to do local searches and are looking for more information on the website, will go to the website and if it’s mobile optimized they will be able to find the information they seek a whole lot easier. It increases a customers likeliness to do business with them by 52%.
Email is great and lots of people use there cell phones to look at email, but also people use there cell phones to do SMS texting. And 95% of text messages are opened as opposed to 5% of email.
Just some extra things to consider.
Really mobile phones are becoming essential part in our personal as well as in professional life and we can understand this fact by the above estimation. I also want to clear one more thing about mobile marketing. As in case of performing mobile marketing there is generating a big trend of bulk sms marketing. Mobile marketing with bulk sms marketing can really change the marketing strategy of business organizations.
Mobile email is on the rise, as more and more people own a smart phone or a mobile device like a tablet.We compiled all available statistics to give insight into the current state of mobile email usage.
