Early Developments Leading to Email
Before email existed, digital communication was limited to mainframe messaging systems and time-sharing networks. In the 1960s, researchers at MIT and other institutions developed early messaging systems that allowed users to leave messages for each other on shared computer systems. These primitive systems laid the groundwork for what would become email.
The development of ARPANET (Advanced Research Projects Agency Network) in 1969 was the crucial breakthrough that made email possible. ARPANET connected different computers across research institutions, creating the first wide-area network that could support inter-computer communication.
Brief History of Email
Have you wondered when was the first email sent?
It was sent in 1971. Ray Tomlinson was the man behind this revolutionary step in email correspondance. He came up with an innovative software called SNDMSG. He sent this history-making email to a desktop that was present in his own room in order to check the efficiency of the software. He was the one who started using the “@” symbol while sending emails.
However, the noteworthy thing is that the term “email” was coined much later.
How To Prevent Email-Based Phishing and Spoofing Attacks?
Today’s organizations can dramatically reduce phishing and spoofing risks by implementing robust email authentication protocols, like SPF, DKIM, DMARC, and BIMI. PowerDMARC’s centralized platform makes it easy to deploy, monitor, and maintain these controls across all your domains, with real-time reporting, compliance automation, and 24/7 expert support.
SPF
SPF or Sender Policy Framework specifies the email servers they use to send emails. This makes it challenging for malicious actors to spoof sender information.
DKIM
DKIM is short for DomainKeys Identified Mail, which is based on public key cryptography and works by adding a digital signature to the message header.
DMARC
A DMARC helps specify what to do if an email fails both SPF and DKIM checks by choosing one of the policies- none, reject, or quarantine. The DMARC DNS record also specifies how the recipient can report to the domain owner if an email fails authentication.
BIMI
BIMI is short for Brand Indicators for Message Identification, a protocol that affixes your exclusive brand logo to all your emails via your brand’s email domain.

1971- When was email invented?
If you are wondering when email was invented, it was in 1971 by Tomlinson. He developed a program that let users send messages to different computers that were a part of the ARPANET system.
ARPANET, or Advanced Research Projects Agency Network, was produced by the U.S. Department of Defense Agency. It uses packet-switch technology to send and receive data with built-in error correction and package assembly. It’s actually the first architecture of the internet system.
1973 – First Email Standard
At Darpa, the proposal for the first email standard was made. This included basic things like the fields of to and from, email forwarding, etc.
1976 – The Queen Sent Her First-Ever Email
Queen Elizabeth II sent the first email on ARPANET’s electronic mail program on her visit to the Royal Signals and Radar Establishment. She used the username HME2 (Her Majesty Elizabeth II) and was the first head to do so.
1978 – First Ever Spam Email
In 1978, Gary Thuerk became the “Father of Spam” by sending an email marketing message to multiple ARPANET users. As per his claims, Gary made as much as $13 million by sending phishing and spam emails.
For CISOs: The emergence of spam directly led to regulatory requirements for secure email handling in finance, healthcare, and government sectors. Today, compliance frameworks like PCI DSS and GDPR expect organizations to actively defend against spam and phishing threats.
1979 – Development of Email Program
Shiva Ayyadurai created an interoffice program at the age of 14 while he was at the University of Medicine and Dentistry of New Jersey. He named this program “EMAIL.” He went on to copyright the term in 1982.
1988 – Microsoft Mail
Microsoft Mail came up in 1988 for MAC OS users. This mail service was meant for AppleTalk Networks users to send messages to each other. Microsoft released the second version later in 1991, which was more like the ancestor of Outlook.
1989 – Email Got a Voice
It was in 1989 that people started getting a voice notification – “You’ve got a mail.” The impressive voice of Elwood Edwards garnered him lots of attention. And at the same time, it increased the enthusiasm and excitement of people who received emails. This iconic phrase not only became a part of popular culture but also motivated many non-native speakers to learn English, as understanding these notifications became essential in the growing digital world.
1991 – Email in Space
The first-ever email from space was sent almost 31 years ago by the crew of the Atlantis space shuttle. They used a Macintosh Portable to send the message.
1992 – Multipurpose Internet Mail Extension
MIME or Multipurpose Internet Mail Extension allows people to send emails in different formats such as character sets and multimedia attachments (audio, images, videos etc.)
1993 – The Birth of Webmail
Hallam-Baker, a cybersecurity professional and CERN employee, discovered the first-ever version of webmail. It was just a test version and could not make it to the public arena.
2002 – Wireless email
Blackberry 5810 was released in the year 2002. The first emails to go wireless was through these Blackberry devices in 2002.
2003 – CAN-SPAM Act
The then president George W. Bush passed the CAN-SPAM Act. Also known as Controlling the Assault of Non-Solicited Pornography And Marketing, this Act aimed at regulating commercial emails.
2004 – Gmail
Gmail was launched in the year 2004. It became a complete game changer and gave tough competition to webmail competitors. Back then, Gmail used to offer a storage space worth 1 GB. Gmail also introduced features like email threads and enhanced search options.
2010 – Responsive Emails
With easy accessibility to smartphones and iPhones, the biggest challenge was making email smartphone friendly. 2010 was the time around which efforts started being made to make these emails responsive. Smartphone users could now open emails on their smartphones. This shift also paved the way for specialized email uses, such as invoice email marketing, where businesses could conveniently send digital invoices to customers on any device.
2012 – Presidential Email Success
Obama has always been a torchbearer of modernization. In 2012 during his re-election campaigns, team Obama embraced email marketing and social media marketing to reach out to the common people. The subject on his emails always read, “Hey!”
How Email Became Popular for Public Use
Email’s transition from academic and military use to widespread public adoption occurred gradually through the 1980s and 1990s. The introduction of commercial internet service providers (ISPs) in the late 1980s made email accessible to businesses and individuals outside research institutions.
Key factors in email’s public adoption included:
- The rise of personal computers in the 1980s
- Commercial ISPs offering email services
- The launch of webmail services like Hotmail (1996) and Yahoo Mail (1997)
- Gmail’s introduction in 2004 with unprecedented storage capacity
By the early 2000s, email had become the primary form of digital communication for both personal and business use, setting the stage for today’s security challenges.
Is Email Secure Today?
No! Emails cannot be considered 100% safe. Although email authentication protocols like DMARC make emails safer for business. There are still some potential threats that you must be aware of.
- An Email Goes Through Multiple Networks
When an email is sent, it goes through multiple networks and servers. At each server or network, there is a potential threat of the email getting intercepted by hackers.
- The Sender of an Email Has Absolutely No Control
After sending an email, you lose control over it completely. Threat actors can access it to attempt malicious activities like scamming. They can also forward it to your prospects and clients by creating malicious attachments. Since the email body speaks about your company, you’ll be held accountable for all the nefarious activities.
- Email Encryption is Not 100% Fail-Proof
Email encryption is vulnerable to hacking. Previously, in Outlook, a glitch was discovered called EFAIL. Later in 2019, it was discovered that attackers could run commands posing as admins.
- Phishing Risk is Increasing With Every Passing Day
Phishing is often used to gather users’ personal information, such as credit card details, usernames, and passwords. Phishing emails are used by imposters to trick you into sharing confidential and sensitive details, which are exploited to attempt nefarious activities in your name or make monetary transactions. Even spam filters fail to block phishing attempts completely.
