Yahoo uses spam filters to detect and remove unwanted emails. If your Yahoo mail account receives a suspicious message, it may be automatically directed to the “Spam” filter. This feature can help keep your inbox uncluttered and prevent spammers from discovering you have an active email address, however it may also accidentally cause you to miss important emails mistaken for spam. To prevent this problem, create a safe list or white list filter on your Yahoo mail account. Yahoo sends mail from a domain that matches the safe list filter directly to your inbox. Tips Writer Bio
