I am receiving Spam e-mails from the Nextdoor organisation even though I cancelled membership on 12 April 2026. I set up a Rule in the Outlook system to block all e-mails received from 2 specific `Nextdoor’ mailboxes. Although these e-mails do not appear in my Inbox they are directed to the Spam folder, which fills up with more spam mail from the same source every time I empty it. The new spam shows dates from before 12 April (when I cancelled the account).
E-mail Guard does not allow me to block or automatically delete these spam e-mails. Does it have any other function that could help to block them?
