For this report, an invalid email format is defined as any email address that: Is missing an email ID, such as @example.com. Is missing the @ symbol, such as johndoeexample.com.

An email address can have a total length of 320 characters. Note that a domain name is limited to 63 characters as specified in section 2 of the same RFC: A DNS label may be no more than 63 octets long.

Formatting? Email addresses must consist of 4 components: the regional address, @, the domain name, and the domain name identifier. If an email address is missing any of these components, it will be invalid, and there will be no inbox for messages.
