The Breakdown of Email Service Usage Among Businesses

Email remains a crucial communication tool for businesses of all sizes. However, the choice of email service provider can vary significantly depending on factors such as company size, industry, and specific needs. In this blog post, we'll explore the usage statistics of popular email services like Gmail (or Google Workspace), Outlook, Proton Mail, Zoho, and Yahoo among businesses.

Gmail (or Google Workspace)

Gmail, part of Google's suite of productivity tools known as Google Workspace (formerly G Suite), has gained widespread adoption among businesses, particularly small and medium-sized enterprises (SMEs). According to a report by Oberlo, Gmail accounts for 30.57% of the global email client market share. While this statistic doesn't specifically differentiate between personal and business usage, it's worth noting that many SMEs opt for Gmail due to its affordability, ease of use, and integration with other Google tools like Drive, Docs, and Calendar.Furthermore, a CIO article highlights the popularity of Gmail among small businesses, citing its ecosystem of third-party tools that enhance productivity and customer support. The article suggests that a significant portion of small businesses rely on Gmail for their business communication needs.

  • In the United States, Gmail has captured 75.78% of the email market share for businesses.
  • Google Workspace has over 6 million paying business customers worldwide as of March 2024, including businesses of all sizes.
  • Google Workspace is used by over 40% of Fortune 500 companies.
  • Gmail Statistics show that 90% of the start-up businesses in the United States of America use Gmail accounts.
  • In the United States of America, as of 2023, around 60% of businesses are using Gmail as their email service provider.


Microsoft's Outlook is a popular choice among larger enterprises and organizations that have adopted the Microsoft ecosystem. According to Oberlo, Outlook holds a 4.06% market share globally. While this percentage may seem relatively low, it's important to note that Outlook is often the default email client for businesses that use Microsoft's suite of productivity tools, including Office 365 and Exchange Server.

Proton Mail

Proton Mail, a privacy-focused email service based in Switzerland, has gained traction among businesses and individuals concerned about data security and privacy. However, its usage statistics among businesses are not widely reported, and its market share is likely relatively small compared to more mainstream providers like Gmail and Outlook.


Zoho is a comprehensive suite of business applications, including an email service called Zoho Mail. While Zoho caters to businesses of all sizes, its email service is particularly popular among small and medium-sized businesses due to its affordability and integration with other Zoho apps like CRM, project management, and collaboration tools. Unfortunately, specific usage statistics for Zoho Mail among businesses are not readily available.


Yahoo Mail, once a dominant player in the email service market, has seen a decline in recent years. According to Oberlo, Yahoo Mail holds a 2.45% market share globally. While some businesses, particularly smaller ones, may still use Yahoo Mail, its usage is likely limited compared to more modern and feature-rich alternatives like Gmail and Outlook.It's important to note that these statistics provide a general overview of email service usage among businesses, but the actual adoption rates may vary depending on factors such as industry, company size, and specific business needs. Additionally, some businesses may use a combination of email services or have different preferences for internal and external communication.

In conclusion, while Gmail (or Google Workspace) and Outlook dominate the business email service market, particularly among SMEs and larger enterprises respectively, other providers like Proton Mail, Zoho, and Yahoo have their niche user bases. As businesses continue to prioritize productivity, security, and integration with other business tools, the choice of email service provider will remain an important consideration
