Invalid email address close

Here are some common reasons why an email address might be considered invalid:

1. Typo: A simple typo in the email address, such as a missing or extra letter, can make it invalid.
2. Incorrect domain: The domain part of the email address (e.g., @gmail.com) is incorrect or does not exist.
3. Missing or extra @ symbol: The @ symbol is missing or appears more than once in the email address.
4. Invalid characters: The email address contains invalid characters, such as spaces, special characters, or punctuation marks.
5. Length: The email address is too long or too short.
6. Format: The email address does not follow the standard format of local part@domain (e.g., [email protected]).
7. Non-existent domain: The domain part of the email address does not exist or is not a valid domain.
8. Email address is not fully qualified: The email address is not fully qualified, meaning it does not include the domain part (e.g., just "username" instead of "[email protected]").

Some examples of invalid email addresses include:

• @gmail.com (missing local part)
• invalidemail (missing @ symbol)
• [email protected] (missing domain)
• username@gmail (missing.com)
• [email protected] (extra @ symbol)

If you're experiencing issues with an email address being considered invalid, double-check the address for any typos or formatting errors.
