A growing number of mobile phone owners are using their handsets to access their emails, new research has revealed.
According to a report by comScore, 70.1 million consumers in the US used their mobiles to read emails during November 2010.
This is 36 per cent higher than the amount recorded during the same period of the previous year.
Researchers at comScore attributed this partly to the growing take-up of internet-enabled smartphones among American consumers.
Indeed, figures showed that more than three-quarters of people who own a smartphone use it to log into their email account.
Mark Donovan, senior vice president of mobile at comScore, commented: "What we have seen in the smartphone era is the rapid acceleration of data consumption, which has helped drive mobile usage across multiple categories including email."
He noted that digital communications technology has evolved considerably in the last few years, as people now have a variety of tools which they can use to communicate with others via the internet.
Mr Donovan said the emergence of social media, instant messaging technology, texting and mobile devices means consumers can do this anywhere and at any time.
The report from comScore also revealed that the number of people who use their mobile phone to access their emails every day is on the rise.
Statistics showed that 43.5 million consumers in the US used mobile email facilities on a "nearly daily basis" during November last year.
This is 40 per cent up on the figure recorded in the corresponding period of 2009.
The report comes shortly after a separate study by comScore found that the overall number of smartphone owners in the US increased between September and November last year.
Figures indicated that the amount went up by ten per cent on the previous three-month period to 61.5 million.
