Block or unblock senders as junk email
Your email server checks incoming messages for characteristics that mark them as spam or junk. To classify messages from a particular email address or domain as spam, you have the option to block them. Alternatively, to stop messages from being moved to your Junk Email folder, add the email address or domain to a list of safe senders.
Select the appropriate tab based on the email platform you're using.
