As spammers create new ways to find their way into your inbox, our system will adapt to try and prevent new methods. Sometimes this will affect who can email you, even those you have been communicating with in the past.
To ensure you are getting your emails from certain people or companies, please be sure to add either their specific email or the domain name to your online trusted senders list.
Once you have added some one to your trusted senders list online, these people will no longer be flagged as spam or potential spam and should now allow their emails to come through without issue.
