Block or unblock senders as junk email
Your email server scans incoming messages for certain traits that identify it as unwanted junk. When you want to treat messages from an email address or domain as junk, you can 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.
