How to unblock spam email?

Hey Rene3334,

Thanks for the question. The following information may be helpful:

Troubleshooting false-positives

Due to the complexity of accurately detecting and filtering out junk mail, on rare occasions a legitimate email from a friendly source may be blocked from reaching your Inbox. This is called a false positive.

If you feel that a legitimate email message was inadvertently filtered, you may want to ask your friend to send a follow-up email to verify that the issue exists. If you notice that multiple email messages are being delayed, bounced, or not delivered, contact iCloud Support. Also make sure to check your Junk folder for email messages that were incorrectly marked as junk mail. To check your Junk folder at iCloud.com, choose the Mail application and click the Junk folder in the sidebar. Email messages in the Junk folder are automatically deleted after 30 days.
