Log into your Sunrise webmail. In order to ensure that certain e-mails do not end up in the "Spam" folder in the future, proceed as follows.
- Open the "Spam" folder.
- Select the e-mail concerned and click the "No Spam" button.
- The e-mail will now be moved to your inbox (Inbox folder). Future e-mails from this sender will then cease to be treated as spam, meaning they will no longer be automatically sent to the "Spam" folder.
