Table of Contents

Have you ever thought about a common thing of social media, weekly or monthly newsletters, or blog sites?  All are looking for your email address. The perfect email address format is very important for any email campaign. So you have to know what is the perfect email address format and what email you should avoid.

A marketer always trying to deliver their email to the correct person, not someone who doesn’t want that. When you’re interested in getting something from them you just put your email address when they’re asking! That’s an amazing and proper way to get your potential clients or the readers of your newsletter. Just think, if you have to collect each and every email address by meeting, calling, or sending a message, it will take years to get all of your potential customers. However, there is a negative aspect to all of this. Emails that are signed up for your newsletter can be fraudulent! How can you know if an address is correct or if it exists? How can you differentiate an authentic email from a fake one? Invalid email addresses may cost you valuable time and money while entering your database. The first email address appeared in 1970 as part of an internal computer message system which was at the Massachusetts Institute Of Technology. Because the communication computers were nearby, no one needed to get creative with email addresses, which consisted of a username, the @ symbol, and the name of the machine meant to get the message at the moment.

After that as the internet evolved into what it is today, and the Domain Name System (DNS) gained importance, naming standards evolved to accommodate for the flood of new sites to which one may route a message. The system of sending email remained the same but the ways are being different day by day.

An Email Address Structure

An Email Address Structure

Requests for Comments (RFC) papers released by the Internet Engineering Task Force and the Internet Society govern the syntax of an email address. They work together to establish guidelines for Internet usage in general. RFC 5322 is concerned with electronic mail, also known as email. To be considered deliverable, an address must, at the most basic level, follow the requirements outlined below.


The username, you enter and the service provider understands it’s you, also known as the local part, can sometimes be up to 64 characters long and can contain any type combination of letters, integers(Positive numbers), or other 7-bit ASCII special characters.
Duration is also permitted in the local part, as long as they are not the first or final character and are not sequential.

Domain name

The domain portion of the email address is subject to specific rules and regulations. It cannot be bigger than 255 characters and must meet the following requirements:

  • Must meet the hostname criteria ( A device name that is connected to a network)
  • The names must be no more than 63 characters in length and can include Latin letters, numerals 0 to 9, and hyphens.

@ Symbol (At sign)

Here is the transitory link that binds the address altogether. By putting the @ symbol, you tell your email application that the first part of your address is your username and the second part is the domain name. You simply do not have an email address if you do not have it!

.com/.net/.org etc after the domain name

Here is the cherry on the dessert. ICANN (Internet Corporation for Assigned Names and Numbers) prohibits domains without a (dot).com/.org/.net etc. ending due to its potential for security problems
An email address from outside the US may include an extra component after the dot com. For example, a Canadian email may look like this: [email protected]

Top-Level Domain

High-level domains would be the top level in the system of the internet as it is related to the Google ranking. This prefix is added after the domain name when an individual or a company buys the domain from a domain registrar.

Examples of the top-level domains-
.net, .com, .org, .xyz

Examples of some email addresses with the top-level domain-

Name on display

The name that displays in the inbox of the receiver. (For example, John Doe may be reached at [email protected].) We recommend that you set up your display name as soon as possible since it makes it easier to recognize who has sent an email at a look.
This might also be the name of a business, company, or department.

Proper Email Address

How Does a Proper Email Address Looks Like

In order to obtain excellent email validation, we must first learn the pattern or format of an email address, as well as how email addresses work.
There are two types of email addresses that we encounter these days. Personal email addresses are listed first, followed by a company or commercial email address.

The company’s email address is:

There are a few commonalities between how corporate emails and personal email accounts are built. Business or corporate email addresses are often generated by combining an employee’s first name or both first and last names with the domain name of the organization/company.
This combination is known as a “pattern.” In most cases, The email addresses in a corporation take a similar approach to their email addresses.
For example [email protected]
In most circumstances, the customized domain names used mostly for corporate or official email addresses are the same as the principal domain name used for your company’s website, although this may not be the case in other instances. It is rather straightforward to set up an email account with a personalized/customized domain name these days, and most email service providers will provide you the choice of a custom domain when you subscribe to a paid subscription.
There are several trustworthy email service providers that offer Business Email hosting. And including Microsoft’s Office 365, Zoho Mail, and others, Google’s G Suite package is undoubtedly the most popular and easy-to-use business email provider.

Personal email:

Personal email addresses follow a pattern that is fairly similar to business email addresses. For instance, [email protected].
As we can see, the email pattern is [email protected]. Gmail is an email service provided by Google. It might be Yahoo, Hotmail, Microsoft Outlook, or whatever else. All of those companies provide free email services for personal email. Recently, Gmail has been used worldwide by most people.

Specific Characteristics and Punctuation

To get your emails refused, avoid using specific special characters:

For the purpose of security, some characters in the local part of an address should be ignored due to the way many programmers set up mail systems. Commas, asterisks, carets, and apostrophes can cause email systems to malfunction and make a message unreceived. Many email providers won’t allow users to use these characters in a username in the first place, so users won’t have to worry about it.

The period in a Gmail account is irrelevant:

Google neglects any periods in an email address’s username, thus [email protected] and [email protected] are almost the same. So if someone registers [email protected] as your email address, they will continue to receive emails sent to [email protected].
Please keep in mind that this is only applicable to Google accounts. Periods do important with many other email providers, such as Yahoo, Zoho Mail, or Outlook, and the spellings at the time of signup should follow whatever the user initially entered as the email username.

Email Addresses aren’t Case Sensitive:

This implies that if somebody registers the account [email protected], the system will still interpret it as [email protected]. They can join up for other services using JOHN DOE or john doe (so on and so forth), but they will continue to get emails at [email protected]. Email accounts receive addresses in the same way. this includes the numbers or letter match; the case(small or big letters) is irrelevant. This is true for email services such as Yahoo mail and Gmail. To know more about email address case sensitive go to our other blog.
