"Blacklist" or "Reclassify Message as Spam"

[Guest JohnRob]

I have Eset Internet Security v15 ... on a Windows 10 PC and I'm using Outlook 2019 for my email.

When I receive spam I use the Eset Outlook tab and have 4 options:

 

1. Reclassify Message as Spam
2. Reclassify Message as NOT Spam
3. Blacklist
4. Whitelist

Can someone tell me the difference between "Blacklist" and "Reclassify Message as Spam"?   A search on eset help doesn't show "Reclassify Message as Spam"

Thank you
