Enter information for the new contact, especially the contact’s sending email address.
This method does not guarantee messages from the desired sender won’t be sent to the junk folder, but it’s an easy way to make it more likely the desired email will arrive in your inbox. When you add a sender’s email address to your contacts, it tells iCloud you want to receive email from that sender. If a desired email message is already in your junk folder, you can use an option to train the iCloud spam filter to not send those messages to your junk folder. To help keep important email messages out of your iCloud email junk folder, you can add the sender email address to your iCloud Contacts. Add an email address to your Apple iCloud white list or safe sender list
