What is the difference between a blocklist and a blacklist?

There is no functional difference. Both a blacklist (or blocklist) refer to a list of IP addresses or domains identified as sources of spam or malicious activity.

Why do I need documentation for DMARC?

DMARC is highly technical. Good documentation and a knowledge base help you understand why emails are failing authentication and how to fix them without breaking your legitimate mail flow.

Is there a free way to monitor DMARC?

Yes, several tools like Suped offer a free tier. These are usually limited by email volume but are perfect for starting your journey toward p=reject.
