Next to social networks and texting, email — at about 293 billion sent per day — is the most utilized cloud service in the world. Don’t believe anybody who tells you that email is dead or dying. It’s not, and it won’t fade away for a long while — it’s too valuable a service, especially for business. Starting back in the mid-’90s with AOL, Yahoo, and Microsoft’s Hotmail and continuing through the present time with Google’s Gmail, Microsoft’s Outlook, and a long list of others, free-of-charge cloud-based email has been a mainstay of daily work for more than a generation.
Email used to be a simple system to send messages over the internet instead of through the mail. Since its creation in 1971, email has been quietly moving into many aspects of our daily lives, such as automated notifications for medical and automotive check-ups, home security monitoring, and company collaboration. It’s become a way of automating our lives.
Hosted commercial email services also use cloud connections and offer add-on services as needed by users mostly employed in enterprises. Here’s a compilation of what you need to know about selecting and using a cloud-based email service — and, yes, you may not know everything.
Data Point No. 1: Email using any kind of cloud exchange is separated from an enterprise’s private communication infrastructure.
InfoSec specialists prefer to distrust any outside service that carries a business’s private information. This is why an increasing number of government, military, scientific, and highly-regulated enterprises are moving to private interconnect systems that operate outside the public internet. This isn’t so much the case, however, with enterprises of all sizes. Using a publicly available cloud-based email service means that your ability to email and connect with your colleagues continues through the internet in the event an internal server fails. In contrast, a private exchange is built into the internal infrastructure, making workplace collaboration completely dependent on the internal connection. If the internal server goes down, so does email.
A benefit of hosting your own email is that messages are sent within the office, making the transfer a little quicker than with the cloud. With a cloud exchange, emails are sent outside the office for storage and are then brought back inside to the recipient’s inbox, slowing down exchange speed. In addition to swift email transfer, private exchange offers settings to enhance workplace collaboration, such as setting custom email sending size and security restrictions. These settings are unique to private exchange and represent a glaring contrast to the one size fits all approach of cloud-based exchange.
Whether your business decides to use a private or cloud exchange, it’s important to understand the upside and downside of each exchange system. Your business and day-to-day operations will determine which exchange is best for you. With the rapid development of this and edge computing, how will your business use email for optimal performance? That’s the important question.
Data Point No. 2: Top five most-deployed free cloud-based email services
Chances are high that you use one of the following email accounts:
Google Gmail: It’s reliable, quick-reacting, has plenty of options, and Is intuitive to learn. According to Androidpolice, Gmail is the most used service worldwide. As of early 2021, Gmail had about 1 billion registrants and 750,000 active users. Disclosure: Strings of email conversations can be hard to follow; it can take a bit of search to find the latest comments. Like anything else, the more one uses it, the more automatic the navigation becomes.
Microsoft Outlook: It’s in second place with 400 million active users. It can be used independently from the Office 365 platform and has big advantage in that it is pre-installed in Windows PCs. It’s very responsive and intuitive to use.
Yahoo Mail: No. 3 with nearly 230 million active users. Many of these are old-schoolers who started using Yahoo Mail back in the 1990s, when it and AOL owned the market before Google and Microsoft forged ahead in the early 2000s. Not known as the fastest-reacting email service in the past, it has made improvements recently.
Yandex Mail: Yandex is a popular search engine for news reading, claiming about 85 million monthly users.
Mozilla Thunderbird: Thunderbird’s team has been working to improve the service’s user interface and UX, with better Gmail support and native notifications for Windows, Mac and Linux — the three operating systems Thunderbird supports for its 25 million users.
Additional cloud email items:
NetEase Mail: The Chinese internet company, born in 1997, mainly competes in the online gaming business but also provided email for a reported 300 million users in 2017. However, those numbers were difficult to verify. The company does see continuous strong growth in Asia in 2021, and the market estimates are that it now serves about 500 million users for games and email.
AOL: The iconic market leader in the early days of the internet is being phased out as Verizon sells its media assets to Apollo Global Management. But the iconic America Online brand, the gateway to the web in the 1990s, is officially no more.
