What is E-mail?

E-mail is defined as the transmission of messages on the Internet. It is one of the most commonly used features over communications networks that may contain text, files, images, or other attachments. Generally, it is information that is stored on a computer sent through a network to a specified individual or group of individuals.

Email messages are conveyed through email servers; it uses multiple protocols within the TCP/IP suite. For example, SMTP is a protocol, stands for simple mail transfer protocol and used to send messages whereas other protocols IMAP or POP are used to retrieve messages from a mail server. If you want to login to your mail account, you just need to enter a valid email address, password, and the mail servers used to send and receive messages.

Although most of the webmail servers automatically configure your mail account, therefore, you only required to enter your email address and password. However, you may need to manually configure each account if you use an email client like Microsoft Outlook or Apple Mail. In addition, to enter the email address and password, you may also need to enter incoming and outgoing mail servers and the correct port numbers for each one.

Email messages include three components, which are as follows:

• Message envelope: It depicts the email’s electronic format.
• Message header: It contains email subject line and sender/recipient information.
• Message body: It comprises images, text, and other file attachments.

The email was developed to support rich text with custom formatting, and the original email standard is only capable of supporting plain text messages. In modern times, email supports HTML (Hypertext markup language), which makes it capable of emails to support the same formatting as websites. The email that supports HTML can contain links, images, CSS layouts, and also can send files or “email attachments” along with messages. Most of the mail servers enable users to send several attachments with each message. The attachments were typically limited to one megabyte in the early days of email. Still, nowadays, many mail servers are able to support email attachments of 20 megabytes or more in size.

In 1971, as a test e-mail message, Ray Tomlinson sent the first e-mail to himself. This email was contained the text “something like QWERTYUIOP.” However, the e-mail message was still transmitted through ARPANET, despite sending the e-mail to himself. Most of the electronic mail was being sent as compared to postal mail till 1996.

Differences between email and webmail

The term email is commonly used to describe both browser-based electronic mail and non-browser-based electronic mail today. The AOL and Gmail are browser-based electronic mails, whereas Outlook for Office 365 is non-browser-based electronic mail. However, to define email, a difference was earlier made as a non-browser program that needed a dedicated client and email server. The non-browser emails offered some advantages, which are enhanced security, integration with corporate software platforms, and lack of advertisements.

Uses of email

Email can be used in different ways: it can be used to communicate either within an organization or personally, including between two people or a large group of people. Most people get benefit from communicating by email with colleagues or friends or individuals or small groups. It allows you to communicate with others around the world and send and receive images, documents, links, and other attachments. Additionally, it offers benefit users to communicate with the flexibility on their own schedule.

There is another benefit of using email; if you use it to communicate between two people or small groups that will beneficial to remind participants of approaching due dates and time-sensitive activities and send professional follow-up emails after appointments. Users can also use the email to quickly remind all upcoming events or inform the group of a time change. Furthermore, it can be used by companies or organizations to convey information to large numbers of employees or customers. Mainly, email is used for newsletters, where mailing list subscribers are sent email marketing campaigns directly and promoted content from a company.

Email can also be used to move a latent sale into a completed purchase or turn leads into paying customers. For example, a company may create an email that is used to send emails automatically to online customers who contain products in their shopping cart. This email can help to remind consumers that they have items in their cart and stimulate them to purchase those items before the items run out of stock. Also, emails are used to get reviews by customers after making a purchase. They can survey by including a question to review the quality of service.

History of E-mail

As compared to ARPANet or the Internet, email is much older. The early email was just a small advance, which is known as a file directory in nowadays. It was used to just put a message in other user’s directory in the place where they were able to see the message by logging in. For example, the same as leaving a note on someone’s desk. Possibly MAILBOX was used at Massachusetts Institute of Technology, which was the first email system of this type from 1965. For sending messages on the same computer, another early program was SNDMSG.

Users were only able to send messages to several users of the same computer through email when the internetworking was not beginning. And, the problem became a little more complex when computers began to talk to each other over networks, we required to put a message in an envelope and address it for the destination.

Later in 1972, Ray Tomlinson invented email to remove some difficulties. Tomlinson worked (Like many of the Internet inventors) for Newman and Bolt Beranek as an ARPANET contractor. To denote sending messages from one computer to another, he picked up the @ symbol from the keyboard. Then, it became easy to send a message to another with the help of Internet standards; they were only required to propose [email protected] One of the first users of the new system was Internet pioneer Jon Postel. Also, describing as a “nice hack,” credited goes to Jon Postel.

Although the World Wide Web offers many services, email is the most widely used facility and remains the most important application of the Internet. On the international level, over 600 million people use email. There were hundreds of email users by 1974, as ARPANET ultimately encouraged it. Furthermore, email caused a radical shift in Arpa’s purpose, as it became the savior of Arpanet.

From there were rapid developments in the field of the email system. A big enhancement was to sort emails; some email folders for his boss were invented by Larry Roberts. To organize an email, John Vittal developed some software in 1976. By 1976 commercial packages began to appear, and email had really taken off. The email had changed people and took them from Arpanet to the Internet. Here was appeared some interesting features that ordinary people all over the world wanted to use.

Some years later, Ray Tomlinson observed about email. As compared to the previous one, any single development is stepping rapidly and nearly followed by the next. I think that all the developments would take a big revolution.

When personal computers came on the scene, the offline reader was one of the first new developments. Then, email users became able to store their email on their own personal computers with the help of offline reader and read it. Also, without actually being connected to the network, they were able to prepare replies like Microsoft Outlook can do today. In parts of the world, this was specifically useful for people where the telephone was expensive as compared to the email system.

Without being connected to a telephone, it was able to prepare a reply with connection charges of many dollars a minute and then get on the network to send it. Also, it was useful as the offline mode allowed for more simple user interfaces. In this modern time of very few standards being connected directly to the host email system often resulted in no capacity for text to wrap around on the screen of the user’s computer, and backspace keys and delete keys may not work and other such annoyances. Offline readers helped out more to overcome these kinds of difficulties.

The SMTP (simple mail transfer protocol) was the first important email standard. It was a fairly naďve protocol that is still in use. And, it was made in terms of no attempt to find the person who sent a message that was the right or not what they claimed to be. In the email addresses, fraudulent was very easy and is still available. Later, these basic flaws were used in the protocol by security frauds, worms and viruses, and spammers forging identities. From 2004, some of these problems are still being processed for a solution.

But as developed email system offered some important features that helped out people to understand easily about email. In 1988, Steve Dorner developed Eudora that was one of the first good commercial systems. But it did not appear for a long time after Pegasus mail come. Servers began to appear as a standard when Internet standards POP (Post office protocol) for email began to mature. Each server was a little different before standard post office protocol (POP). POP was an important standard that allowed users to work together.

Individual dialup users were required to charges for an email per-minute in those days. Also, on the Internet, email and email discussion groups were the main uses for most people. There were several issues on a wide variety of subjects; they became USENET as a body of newsgroups.

With the World Wide Web (WWW), email became available with a simple user interface that was offered by providers like Hotmail and Yahoo. And, users did not require to pay any charges on these platforms. Now everyone wanted at least one email address as it is much simple and affordable, and the medium was adopted by millions of people.

Internet Service Providers (ISPs) started to connect people with each other all over the world by the 1980s. Also, by 1993 the use of the Internet was becoming widespread, and the word electronic mail was replaced by email.

Today, email has become a primary platform to communicate with people all over the world. There are continuing updates to the system with so many people using email for communication. Although email has some security issues, there have been laws passed to prevent the spread of junk email over the years.

Advantages of Email

There are many advantages of email, which are as follows:

• Cost-effective: Email is a very cost-effective service to communicate with others as there are several email services available to individuals and organizations for free of cost. Once a user is online, it does not include any additional charge for the services.
• Email offers users the benefit of accessing email from anywhere at any time if they have an Internet connection.
• Email offers you an incurable communication process, which enables you to send a response at a convenient time. Also, it offers users a better option to communicate easily regardless of different schedules users.

• Mass sending: You can send a message easily to large numbers of people through email.
• Email exchanges can be saved for future retrieval, which allows users to keep important conversations or confirmations in their records and can be searched and retrieved when they needed quickly.
• Email provides a simple user interface and enables users to categorize and filter their messages. This can help you recognize unwanted emails like junk and spam mail. Also, users can find specific messages easily when they are needed.
• As compared to traditional posts, emails are delivered extremely fast.
• Email is beneficial for the planet, as it is paperless. It reduces the cost of paper and helps to save the environment by reducing paper usage.
• It also offers a benefit to attaching the original message at the time you reply to an email. This is beneficial when you get hundreds of emails a day, and the recipient knows what you are talking about.
• Furthermore, emails are beneficial for advertising products. As email is a form of communication, organizations or companies can interact with a lot of people and inform them in a short time.

Disadvantages of Email

• Impersonal: As compared to other forms of communication, emails are less personal. For example, when you talk to anyone over the phone or meeting face to face is more appropriate for communicating than email.
• Misunderstandings: As email includes only text, and there is no tone of voice or body language to provide context. Therefore, misunderstandings can occur easily with email. If someone sends a joke on email, it can be taken seriously. Also, well-meaning information can be quickly typed as rude or aggressive that can impact wrong. Additionally, if someone types with short abbreviations and descriptions to send content on the email, it can easily be misinterpreted.
• Malicious Use: As email can be sent by anyone if they have an only email address. Sometimes, an unauthorized person can send you mail, which can be harmful in terms of stealing your personal information. Thus, they can also use email to spread gossip or false information.

For instance, instead of sending it to a single person, you can accidentally send sensitive information to a large group of people. Thus, the information can be disclosed, when you have clicked the wrong name in an address list. Therefore, it can be harmful and generate big trouble in the workplace.
• Spam: Although in recent days, the features of email have been improved, there are still big issues with unsolicited advertising arriving and spam through email. It can easily become overwhelming and takes time and energy to control.
• Information Overload: As it is very easy to send email to many people at a time, which can create information overload. In many modern workplaces, it is a major problem where it is required to move a lot of information and impossible to tell if an email is important. And, email needs organization and upkeep. The bad feeling is one of the other problems with email when you returned from vacation and found hundreds of unopened emails in your inbox.
• Viruses: Although there are many ways to travel viruses in the devices, email is one of the common ways to enter viruses and infect devices. Sometimes when you get a mail, it might be the virus come with an attached document. And, the virus can infect the system when you click on the email and open the attached link. Furthermore, an anonymous person or a trusted friend or contact can send infected emails.
• Pressure to Respond: If you get emails and you do not answer them, the sender can get annoyed and think you are ignoring them. Thus, this can be a reason to make pressure on your put to keep opening emails and then respond in some way.
• Time Consuming: When you get an email and read, write, and respond to emails that can take up vast amounts of time and energy. Many modern workers spend their most time with emails, which may be caused to take more time to complete work.
• Overlong Messages: Generally, email is a source of communication with the intention of brief messages. There are some people who write overlong messages that can take much time than required.
• Insecure: There are many hackers available that want to gain your important information, so email is a common source to seek sensitive data, such as political, financial, documents, or personal messages. In recent times, there have various high-profile cases occurred that shown how email is insecure about information theft.

Different types of Email

There are many types of email; such are as follows:

Newsletters: It is studying by Clutch, the newsletter is the most common type of email that are routinely sent to all mailing list subscribers, either daily, weekly, or monthly. These emails often contain from the blog or website, links curated from other sources, and selected content that the company has recently published. Typically, Newsletter emails are sent on a consistent schedule, and they offer businesses the option to convey important information to their client through a single source. Newsletters might also incorporate upcoming events or new, webinars from the company, or other updates.

Lead Nurturing: Lead-nurturing emails are a series of related emails that marketers use to take users on a journey that may impact their buying behavior. These emails are typically sent over a period of several days or weeks. Lead-nurturing emails are also known as trigger campaigns, which are used for solutions in an attempt to move any prospective sale into a completed purchase and educate potential buyers on the services. These emails are not only helpful for converting emails but also drive engagement. Furthermore, lead-nurturing emails are initiated by a potential buyer taking initial action, such as clicking links on a promotional email or downloading a free sample.

Promotional emails: It is the most common type of B2B (Business to Business) email, which is used to inform the email list of your new or existing products or services. These types of emails contain creating new or repeat customers, speeding up the buying process, or encouraging contacts to take some type of action. It provides some critical benefits to buyers, such as a free month of service, reduced or omitted fees for managed services, or percentage off the purchase price.

Standalone Emails: These emails are popular like newsletters emails, but they contain a limitation. If you want to send an email with multiple links or blurbs, your main call-to-action can weaken. Your subscriber may skip your email and move on, as they may click on the first link or two in your email but may not come back to the others.

Onboarding emails: An onboarding email is a message that is used to strengthen customer loyalty, also known as post-sale emails. These emails receive users right after subscription. The onboarding emails are sent to buyers to familiarize and educate them about how to use a product effectively. Additionally, when clients faced with large-scale service deployments, these emails help them facilitate user adoption.

Transactional: These emails are related to account activity or a commercial transaction and sent from one sender to one recipient. Some examples of transactional email are purchase confirmations, password reminder emails, and personalized product notifications. These emails are used when you have any kind of e-commerce component to your business. As compared to any other type of email, the transactional email messages have 8x the opens and clicks.

Plain-Text Emails: It is a simple email that does not include images or graphics and no formatting; it only contains the text. These types of emails may worth it if you try to only ever send fancy formatted emails, text-only messages. According to HubSpot, although people prefer fully designed emails with various images, plain text emails with less HTML won out in every A/B test. In fact, HTML emails contain lower open and click-through rates, and plain text emails can be great for blog content, event invitations, and survey or feedback requests. Even if you do not send plainer emails, but you can boost your open and click through rates by simplifying your emails and including fewer images.

Welcome emails: It is a type of B2B email and common parts of onboarding emails that help users get acquainted with the brand. These emails can improve subscriber constancy as they include additional information, which helps to the new subscriber in terms of a business objective.

Also, these emails can help businesses to build a better relationship between customers.

Examples of email attacks

Although there are many ways to travel viruses in the devices, email is one of the most common vectors for cyberattacks. The methods include spoofing, spamming, spear-phishing, phishing, ransomware, and business email compromise (BEC).

There are many organizations (around 7710) hit by a BEC attack every month, as one out of every 412 emails contains a malware attack. According to the Symantec Internet Threat Security Report, spear-phishing is the most widely used infection vector. Below is given a complete description of these types of attacks:

• Phishing: A form of fraud in which the attacks are the practice of sending fraudulent communications that appear to come from a reputable entity or person in email or other communication channels. Usually, it is done through the email; phishing emails are used by attackers to steal sensitive data like credit card and login information or to install malware on the victim’s machine. Additionally, everyone should learn about a phishing attack in order to protect themselves, as it is a common type of cyberattack. The common features of phishing emails are Sense of urgency, Hyperlinks, Too Good to Be True, Unusual sender, Attachments.
• Spamming: Spam email is unsolicited bulk messages sent without explicit consent from the recipient, which is also known as junk email. Since the 1990s, spam is a problem faced by most email users and has been increasing in popularity. Obtained by spambots, spam mail recipients have had their email addresses (automated programs), which crawl the Internet to find email addresses. This is the dark side of email marketing in which spammers use spambots to create email distribution lists. Typically, an email is sent by a spammer to millions of email addresses with the expectation that only a few numbers of an email address will respond or interact with the message.
• Spoofing: Email spoofing is an email message that could be obtained from someone or somewhere other than the intended source. It is a popular strategy that is used in spam and phishing campaigns as core email protocols do not have a built-in method of authentication. And, when people think the email has been sent by a legitimate or familiar source, they are more likely to open an email. Thus, it is a common tactic used for spam and phishing emails. The email spoofing is used with the purpose of getting mail recipients to open emails and possibly respond to a solicitation.
• Business email compromise (BEC): A BEC is an exploit in which an authorized person or attacker hacks to a business email account and spoofs the owner’s identity to defraud the company, its customers, partners of money. Often, an attacker simply creates an account with an email address that is almost identical to one on the corporate network, which creates trust between the victim and their email account. Sometimes, a BEC is also known as a man-in-the-email attack. Some samples of BEC email messages that contain the word in subject, such as urgent, transfer, request, payment, and more. There are five types of BEC scams on the basis of the FBI, which are False Invoice Scheme, CEO Fraud, Data Theft, Attorney Impersonation, Account Compromise.
• Spear-phishing: Email spoofing is an attack where hackers target an individual or specific organization to gain sensitive information through unauthorized access. Spear phishing is not initiated by random hackers but attempted by perpetrators to gain financial benefits or secrets information. It is an attack in which attackers send emails to specific and well-researched targets while purporting to be a trusted sender. The main objective of spear phishing is to convince victims to hand over information or money and infect devices with malware.
• Ransomware: It is a subset of malware that is used to encrypt a victim’s files. Typically, it locks data by encryption on the victim’s system. Typically, it locks data by encryption on the victim’s system, and attackers demand payments before the ransomed data is decrypted. Unlike other types of attacks, the primary goal of ransomware attacks is just about always monetary. Usually, when the exploit occurs, a victim is notified about the attack and is given instructions for how to recover from the attack.

Popular email sites

There are some free email website examples include the following:

• AOL
• Zoho
• Gmail
• ProtonMail
• Com
• Microsoft Outlook
• Yahoo Mail

Email is a platform that allows users to communicate with people or groups of people around the world. As email security is more important but consequent, it is not inherently secure.

There are many techniques that can be used by individuals, organizations, and service providers. These techniques provide how to protect sensitive information with email communication and accounts from unauthorized access, loss, or destruction.

Individuals can protect their account with the help of creating strong passwords and changing them frequently. They can use alphabetical, numerical, special symbols to make a strong password that helps to protect your account. Users can also install and run an antivirus and antimalware software on their computer, as well as create spam filters and folders to separate potentially malicious emails and junk mail.

Also, there are some techniques the helps organizations to secure email include implementing an email security gateway, training employees on deploying automated email encryption solutions, and proper email usage. By processing and scanning all received emails, email gateways check emails for threats, and analyze that should be allowed into the system or not. A multilayered gateway is a powerful technique since attacks are increasing rapidly and becoming complicated and sophisticated. Some emails that cannot be caught by the gateway, training employees on how to differentiate malicious messages, and properly use email are the best approach, which helps users avoid threatening mails.

For potentially sensitive information, the automated email encryption solutions are used that scans all outgoing messages; it will encrypt the sensitive information before it is sent to the intended recipient. This process helps to send email securely and prevent hackers from gaining access to the secret information, even if they stop it. The only intended recipient can view the original information with permission.

Email service providers can also help to enhance security with the help of accessing control standards and mechanisms and establishing a strong password. Additionally, providers should also offer digital signatures and encryption solutions to secure emails in transit and in users’ inboxes. Finally, to protect users from malicious, unrecognized, and untrustworthy messages, service providers should implement firewalls and spam-filtering software applications.

E-mail address breakdown

Let’s take an example of [email protected] to describe the breakdown of an email.

In the email address, before the part of the @ symbol, contains the department of an organization, alias, user, or group. As shown in the above example, help is the support department at our company tutoraspire.

Next, the @ (at sign) is required for all SMTP (Simple Mail Transfer Protocol) email address that is a divider in the email address, since the first message was sent by Ray Tomlinson.

Finally, users belong to the domain name, tutoraspire.com. For the domain, the .com is the top-level domain (TLD).

What can be sent in an e-mail?

An email is a platform that enables users to communicate with each other. It allows users to send text messages, including a file or other data on the e-mail all over the world. It is also possible to attach a picture, word processor document, PDF, program, movie, or any file stored on your computer in an e-mail. However, due to some security issues, it may not be possible to send certain types of files on the email; they need some additional steps. For example, the .exe file can be blocked by many companies from being sent over the email, and you will need to compress the file into a .zip file format. Additionally, you may be unable to send any large files or programs from being sent over e-mail as most e-mail providers have file size restrictions.

What should be write e-mail or email?

You can use any word email or e-mail according to the style guide you are following as both are valid and have the same meaning. However, the e-mail word has a hyphen and is a compound noun that describes “electronic” and “mail.”

How to send and receive e-mail

E-mail program

You can use an email program to send and receive an email. An email program is also known as an e-mail client. There are many email programs available to send and receive an email, including Mozilla Thunderbird and Microsoft Outlook. A server is used to store and deliver your messages while you use an email client. Often, your ISP (Internet service provider) host this server but can be another Internet company to host this server. To download the new emails, an email client requires connecting a server, whereas online stored emails are always available on Internet-connected devices.

Online e-mail

An online e-mail service or webmail is an alternative way and the popular solution for most people in sending and receiving e-mail. Examples of online emails are Yahoo Mail, Gmail, and Hotmail (now Outlook.com).

Some of the popular e-mail clients?

Today, there are different software-based e-mail clients available for users, but these are not online. Below is given a list that contains the most popular clients.

• Microsoft Outlookv
• Mail for Windows 10
• DreamMail
• Mozilla Thunderbird
• eM Client
• Mailbird

What makes a valid e-mail address?

Users need to follow the various rule that is given below to make valid email address:

• A username followed by @ (the at sign) is most important for an email address, which is followed by the domain name with a domain suffix. Hence, an e-mail must have a username.
• The domain name cannot be longer than 254 characters, and the username cannot be longer than 64 characters long.
• An email must have only one @ sign.
• An email should not have space and special characters like [ ] ( ) , : ; < >. Sometimes, few symbols such as backslash, space, and quotation mark work must be preceded with a forward slash. But these characters are not allowed by some email providers.
• In the email, the email address and username cannot start or end with a period.
• The two or more successive periods are not allowed in the email.
