I use Outlook (not Outlook365) and find that blocking senders just gets them diverted into the Junk folder so I find myself continually deleting them - I know the Junk folder auto-deletes after 30 days but I like to keep it clear so I can see emails from new suppliers which also go into Junk nuntil I identify them as trusted senders.I find blocked senders come through to my Apple devices from Hotmail and into my Junk, with the “blocked” red circular sign clearly displayed. Yet I get no junk to my Gmail, or Yahoo accounts.
