Email has become an integral part of our daily lives, serving as an essential means of communication. The first step in creating an email account is to select an appropriate username and password. However, not all characters are allowed in email addresses. So, before you start typing away, it’s important to know which special characters are not allowed in email addresses.
The most common characters permitted in email addresses are letters, digits, hyphens, and underscore symbols. Any other character is considered ‘special,’ and these characters can cause errors when you try to use them in your email address. For instance, using a hashtag (#) or ampersand (&) in your email address is strictly prohibited.
Interestingly, email addresses can also contain periods (.) – but not everywhere. Though you can use a period in between characters such as ‘john.smith’ in your email address, using it at the beginning or at the end of the username is not allowed. With that being said, let’s look at some other special characters that you should avoid when creating an email address.
What are special characters in email addresses?
In an email address, special characters are symbols other than letters and numbers, such as !, #, $, %, &, *, +, -, /, =, ?, ^, _, {, |, and }.
Special characters are not typically allowed in email addresses for several reasons:
- They can cause technical issues: Special characters can interfere with email server software, leading to undeliverable or bounced emails.
- They can cause confusion: Many people may not be familiar with certain special characters, leading to typos and errors when typing email addresses.
- They can be used for malicious purposes: Some special characters, such as
<and>, can be used in email addresses to spoof or impersonate legitimate senders.
For these reasons, most email providers and organizations restrict the use of special characters in email addresses.
Which characters are not allowed in email addresses?
Email addresses serve as one of the primary means of communication in today’s digital world. It is important to know the rules and regulations regarding email addresses to ensure that your messages will be sent and received correctly. One crucial aspect of email addresses is the characters that are not allowed. Here are some of the most common special characters that are not allowed in email addresses:
- Spaces
- Quotes (“”)
- Ampersands (&)
- Angle brackets (<>)
- Commas (,)
- Colons (:)
- Semicolons (;)
- Slashes (/ \)
- Question marks (?)
- Exclamation marks (!)
- Pound signs (#)
- Dollar signs ($)
- Percentages (%)
- Asterisks (*)
- Plus signs (+)
- Equal signs (=)
It is also worth noting that email addresses cannot start or end with a period (.), and multiple periods cannot be used consecutively. For example, “[email protected]” is valid, but “[email protected]” is not.
Some email providers also have additional restrictions on the use of special characters. For instance, Google allows the use of periods (.) and plus signs (+) in email addresses, but they are ignored in the actual delivery of the message. On the other hand, Yahoo does not allow periods (.) or plus signs (+) in email addresses.
Conclusion
By keeping in mind the characters that are not allowed in email addresses, you can ensure that your emails will be sent and received without any issues. Additionally, it is important to check the specific rules and regulations of your email provider to avoid any complications or potential delivery failures.
| Email Provider | Allowed Characters | Restricted Characters |
|---|---|---|
| Gmail | Periods (.), plus signs (+) | |
| Yahoo | Periods (.), plus signs (+) |

Why do email providers restrict special characters in addresses?
Special characters such as #$%@ symbol may look cool in email addresses, but they are not always allowed in email addresses. Here are the reasons why email providers restrict special characters in email addresses:
- Technical limitations: Email is a text-based communication system designed to work with ASCII character codes. ASCII is a standard that defines how computers interpret and display text. ASCII only includes 128 characters, and the email system can only handle these characters. The use of other symbols can cause technical errors like messages being undelivered or improperly formatted.
- Security: Special characters can be used in phishing attacks and spam. Cybercriminals can use special characters to create email addresses that look legitimate but are used to steal personal information or infect computers with malware. By limiting the use of special characters, email providers can help prevent these types of attacks.
- User experience: Some special characters are difficult to type or remember, causing confusion and making it difficult for people to send emails to the intended recipients. Using only letters, numbers, and a few standard symbols (like “-” and “.”) makes email addresses easy to understand and remember.
Examples of special characters that are not allowed in email addresses
Some special characters that are not allowed in email addresses include:
| Special Character | Description |
|---|---|
| & | Used for HTML code and can cause email to be formatted improperly. |
| * | Used as a wildcard in search queries and operating systems, can cause delivery issues or mailbox errors if used in email addresses. |
| $ | Used to represent money or financial transactions, can create confusion in email addresses. |
| @ | Used as a delimiter to separate the email username from the domain name. Cannot be used more than once in an email address. |
Overall, the restrictions on special characters make sense given the technical limitations of the email system, the need for security, and the importance of a good user experience.
What happens if I use a special character in my email address?
When creating an email address, there are certain rules that you need to abide by, including the use and avoidance of specific characters. So, what exactly happens if you use a special character in your email address? Here are some things to keep in mind:
- Some email providers do not support special characters in email addresses. If you try to create an email address with a special character that is not supported by your email provider, you will receive an error message and will not be able to proceed with the registration process.
- If you use a special character in your email address and it is accepted by your email provider, it may cause confusion for others who are trying to communicate with you. For example, if you use an exclamation point (!) in your email address, someone may forget to include it when emailing you and the email will not be delivered to your inbox.
- If you use a special character in your email address, other websites and services may not recognize it properly. This could prevent you from completing certain tasks online, such as signing up for a new service or resetting a password on an existing account.
It’s important to note that not all special characters are forbidden in email addresses, but it is generally recommended to avoid them to prevent any potential issues. Here is a table of the special characters that are not allowed in email addresses:
| Character | Description |
|---|---|
| @ | Signifies the location of the email domain |
| . | Used to separate different parts of the email address |
| , | Used in some email clients to separate multiple email addresses |
| ; | Used in some email clients to separate multiple email addresses |
| : | Used in some email clients to separate multiple email addresses |
| “ | Used to enclose email addresses with spaces or special characters |
| \ | Used to escape characters in email addresses |
| / | Used in some email clients to separate multiple email addresses |

In conclusion, it’s important to avoid using special characters in email addresses to prevent potential issues with email providers, communication, and other online services.

When it comes to choosing an email address, certain rules apply. For starters, it needs to stand out and be unique enough to remember. However, it’s also important to ensure that your email address is easy to read and doesn’t include any special characters that could cause issues with delivery.
While many special characters such as underscores and hyphens are allowed, others are not. These special characters include:

Additionally, consider setting up a separate email address for different purposes, such as one for personal use and another for business. This can help keep your emails organized and ensure that important messages aren’t lost in a sea of spam or unrelated correspondence.
Ultimately, choosing the best email address requires some thought and consideration. By avoiding special characters and keeping things professional, you can ensure that your messages are always received and make a lasting impression.

|---|---|
| Memorable and easy to remember | May not be professional or appropriate for all settings |
| Can help with branding and marketing efforts | May be difficult to type or spell correctly |
| Less likely to be confused with others | May require explanation or justification |
