Can caps used in mail id

In an email address, the use of capital letters is not strictly necessary, but it is generally recommended to use them to make the address more readable and to avoid confusion.

Here are some reasons why you might want to use capital letters in an email address:

  1. Readability: Using capital letters can make the email address easier to read, especially if it contains multiple words or special characters.
  2. Uniqueness: Using capital letters can help ensure that your email address is unique and less likely to be confused with someone else's address.
  3. Consistency: Using capital letters consistently throughout the email address can make it easier to remember and type correctly.

However, it's worth noting that:

  1. Email servers don't care: Email servers don't care whether you use capital letters or not. They will still deliver the email to the correct address regardless of the case.
  2. Some systems may not work: Some older email systems or software may not work correctly with email addresses that contain capital letters. However, this is relatively rare.

In general, it's a good idea to use capital letters in your email address to make it more readable and unique. But if you're concerned about compatibility issues, you can still use all lowercase letters or a mix of both.

Here are some examples of email addresses with and without capital letters:
