Cloud email is rising in popularity across the world, as 13 per cent of identified publicly listed companies worldwide utilise one or two of the main cloud email vendors. 

This is according to Gartner, which found that 8.5 per cent of public companies use cloud email from the Microsoft Office 365 service, whereas 4.7 per cent use Google Apps for Work and the remaining 87 per cent use an on-premises, hybrid, hosted or private cloud email through smaller businesses.

Among organisations using cloud email from Google and Microsoft, Microsoft is ahead in the majority of industries, especially in utilities, energy and aerospace. On the other hand, Google is ahead in industry segments where there is more competition, including software publishing, retail, media and education. 

Jeffrey Mann, research vice president at Gartner, said: “Among public companies using cloud-based email, Microsoft is more popular with larger organisations and has more than an 80 per cent share of companies using cloud email with revenue above $10 billion (£69.6 billion).”

Mr Mann went on to say that Google’s popularity is higher among small companies and close to a 50 per cent share of businesses with revenue under $50 million. 

In some sectors, particularly travel and hospitality, professional services and consumer products, the highest usage levels are among organisations with the largest revenues. Over a third of firms in these sectors with revenue above $10 billion utilise cloud email from either Microsoft or Google. 

Nikos Drakos, a research vice president at Gartner, also commented on the development of the industry, finding that both companies have been able to gain significant traction among enterprises of varying sizes and sectors. 

With more businesses now looking to free up as much space as possible, cloud email could be set to increase in popularity in the coming years as organisations look to boost their data security and reduce the chances of information falling into the wrong hands.
