Valid facebook email addresses

Here are some examples of valid Facebook email addresses:

1. username@facebook.com (e.g., [email protected])
2. username@facebookmail.com (e.g., [email protected])
3. username@facebook.net (e.g., [email protected])
4. username@facebook.org (e.g., [email protected])
5. username@facebook.io (e.g., [email protected])

Note that Facebook also allows email addresses with the following formats:

1. username+extension@facebook.com (e.g., [email protected])
2. username@subdomain.facebook.com (e.g., [email protected])

However, these formats are not as commonly used as the ones listed above.

Some examples of invalid Facebook email addresses include:

1. username@gmail.com (since this is a Google email address, not a Facebook email address)
2. username@example.com (since this is a generic example domain, not a Facebook email address)
3. username@facebook.co.uk (since this is a country-specific top-level domain, not a Facebook email address)

Keep in mind that Facebook has specific requirements for email addresses, such as:

• The email address must be unique and not already in use by another user.
• The email address must be in the format of a valid email address (e.g., it must contain an "@" symbol and a domain name).
• The email address must not contain any special characters or spaces.

If you're trying to create a Facebook account or recover a lost password, make sure to use a valid email address that meets these requirements.
