How to undo if I accidentally marked a message as spam

I just picked up I must have accidentally marked an email as spam. How do I do I undo this, so it is no longer seen as a spam message and moved to my spam folder.

Select the message in the Junk folder and by right-click choose Move to Inbox > Move to Inbox and remove Blacklisted …

Or you can edit the Blacklist Rule and remove the address or domain that way.

Thank you Gary. I took the right click move to inbox way. Much easier. You’ve been a great help. Baie dankie. Meaning, thank you very much in Afrikaans.
