Email Is Still an Essential Part of Your Online Presence

​With communication channels and social media platforms continuing to grow, it’s easy to get the impression email is slowly dying. Though email may not be growing as fast as social media platforms and communication tools, it’s still an essential platform for consumers and businesses. According to Radicati the total number of business and consumer emails sent and received per day will exceed 347 billion by 2023ⁱ. 

In this blog, we look at some of the trends the SolarWinds^® Mail Assure threat intelligence team has observed over the past few months in relation to email traffic across some of the top collaboration services, take-out services, travel platforms, streaming services, and delivery services like Amazon—and how lockdown measures across the globe have influenced these trends. 

With a large portion of the world being homebound for the first part of 2020 and relying heavily on collaboration tools for communication, it’s no surprise these types of services have seen an uptick in business. Microsoft Teams now has 75 million daily active usersⁱⁱ and Zoom saw a major spike in March with daily participants (including free and paid) reaching more than 200 millionⁱⁱⁱ. Cisco WebEx also reported growth and a surge in meetings in March^iv while many countries implemented lockdown measures. The graph below shows spikes in email traffic volume in mid-March. The low points correspond with data tracked over weekends.

What does the email traffic represent? For Microsoft Teams, it includes calendar invitations, general updates, account related information, missed chat messages, and much more information sent by Microsoft. Email remains an integral part of such collaboration services. 

Next, we looked at email traffic volume for UberEATS, where email traffic spiked going into March and maintained consistent high volumes. The company reported a 30% increase in sign-ups going into March^vi.

While movie theatres had to shut their doors, streaming services like Netflix gained 15.8 million^viii paying customers for the period January to March, with email volume trends increasing with their growth.

As expected, emails from online delivery services like Amazon also surged as online orders increased^x in March. A consistent upward trend has been observed from the technology giant.

Finally, we analyzed email trend for two of the largest companies in the travel industry. Trends were consistent in February, followed by spikes in March and as expected a drastic decrease as travel restrictions took effect.

With demand for many collaboration and online services spiking drastically in the space of a few months, and with an increase in overall email traffic from these providers, security has become a big challenge. Just like any other business, cybercriminals follow market trends and implement tactics that align with these. In April we reported an increase of over 80% in phishing attacks—and the trend continues. Cybercriminals know businesses and consumers are active on these platforms and are receiving emails from them. Therefore, they disguise meeting invitations and other communications (like the one below) to look like they were sent by the company—making it hard to differentiate between legitimate email and non-legitimate email. 

Cybercriminals constantly challenge you and your customers to ensure you’re investing in the right security solutions to protect your assets against cyberthreats that can potentially lead to costly data breaches. 

Key takeaways:

• Email is not going away any time soon: collaboration tools, online platforms, and demand for online shopping continue to grow, but email remains an essential part of nearly all online subscription, platforms, and services used through the internet. 
• Email continues to be a vulnerability: Email is one of the easiest entry points for cyberattacks because people rely on it to get their jobs done and get connected.
• Practicing strong security programs and awareness is key as the online world evolves.
