What does the term 'Email Invalid' status indicate?

The term 'Email Invalid' status specifically indicates that the email address in question is not formatted correctly. This means that the structure of the email address fails to meet the standard requirements for valid email formatting, such as the presence of an '@' symbol and a proper domain structure. When an email is marked as 'Email Invalid,' it typically cannot be used for sending communications, as the system recognizes that it would not be able to deliver to that address.

In contrast, the other options pertain to different issues related to email addresses. Verification implies that the email address has passed certain checks, which is not the case with 'Email Invalid'. Opting out refers to a situation where users have chosen not to receive communication, which is also unrelated to validity. Lastly, stating that an email is not currently in use suggests that it might be valid but simply inactive, thereby differing from the outright formatting issue signified by the 'Email Invalid' status. Understanding these distinctions is crucial for effective email marketing and management.
