Since Yahoo has the habit of flagging my legit mail as spam (50% of what get flagged as spam is not), I need to know when I have new items in my spam folder. The IOS app does not let me view the SPAM folder anymore. It is is new change. You need to let users view the SPAM folder on the app.
Please download the Yahoo Mail app or use a desktop computer browser to access your mail.
The best way to resolve this is to mark the emails as “Not Spam”, that way you can train the spam filter to better identify important emails in the future. Also if you use a mobile device or email client to access your mail over IMAP, please check the Spam filters in that application, to make sure it’s not marking important emails as spam.
