Are email addresses case sensitive? In some cases, maybe Yes or maybe a No!
There are scenarios where yes email addresses are case sensitive and in some scenarios case insensitive. Now, you might think about how is it possible!
Yes! It is. Let’s understand how and why?
Are Email Addresses Case Sensitive?
An email address is a combination of a username and the domain name (from which the account is created). The ‘@’ sign separates username and domain names from each other. For example – email@example.com.
Where the part before ‘@’ is the username and the part after ‘@’ is the domain name.
Both sides may contain uppercase and lowercase letters. Besides, they also contain periods, special characters, and underscores.
#1 Scenario | Email Addresses Case Insensitive
Now, let’s assume a probability of a person typing an email address incorrectly. He may make lowercase letters uppercase or include a period in between the username.
Johnwick@gmail.com is incorrectly typed as John.Wick@gmail.com. The question here is will it be considered as case sensitive by Google server or not. The quick answer here is No!
Google email addresses ignore the letter case and periods. This is a scenario where email addresses are case insensitive. In this case, the message will likely be delivered to the correct email address – ‘Johnwick@gmail.com‘
#2 Scenario | Email Addresses Case Sensitive
In the case of Gmail, Johnwick@gmail.com is considered the same as John.Wick@gmail.com. But in the case of Yahoo or other domain names, they may not be considered the same.
For example, Johnwick@yahoo.com is not the same as John.Wick@yahoo.com. So, if a person types a wrong username in an email address, the message will unlikely not be delivered.
This is because in some scenarios email addresses are case sensitive.
Understanding Username & Domain Name in an Email Address
The username in an email address is case sensitive (except Google). Example@domain.com is not the same as firstname.lastname@example.org. However, this is not the same in the case of Google email addresses.
Besides, a domain name in an email address is case insensitive which means the case doesn’t matter here. Example@domain.com is considered the same as Example@DOMAIN.com.
