Manage junk mail in Mail on iCloud.com
Most junk mail (spam) sent to your @icloud.com address or its aliases is automatically identified and moved to your Junk folder. If you receive unwanted email, you can manually mark it as junk.
Important: Because emails in the Junk folder are automatically deleted after 30 days, periodically check the Junk folder for emails that were mistakenly marked as junk.

Do one of the following:
