Valid email

A valid email address typically follows the format of:

[email protected]

Where:

• localpart is the part of the email address that comes before the @ symbol, and can contain letters, numbers, and special characters (except for spaces and punctuation marks).
• domain is the part of the email address that comes after the @ symbol, and is usually a domain name (e.g. gmail.com, yahoo.com, etc.).
• tld is the top-level domain (e.g. .com, .org, .net, etc.).

Here are some examples of valid email addresses:

• [email protected]
• [email protected]
• [email protected]
• [email protected]

And here are some examples of invalid email addresses:

• john [email protected] (spaces are not allowed in the local part)
• jane.smith@ (missing top-level domain)
• hello.world@ (missing top-level domain)
• info@ (missing domain)

Note that some email providers may have additional requirements or restrictions on email addresses, such as:

• Maximum length: Most email providers have a maximum length for email addresses, typically around 64 characters.
• Special characters: Some email providers may not allow certain special characters, such as @, #, or %, in the local part.
• Domain restrictions: Some email providers may only allow email addresses from specific domains or subdomains.

It's always a good idea to check with the email provider or organization to see if they have any specific requirements or restrictions on email addresses.
