What is the Blacklist Monitor?
Check your domains against Spamhaus, SURBL, Barracuda, and URIBL.
The Blacklist Monitor checks every unique domain in your upload against four major DNS-based blacklists. A blacklisted domain indicates that mail servers worldwide have flagged it for spam, phishing, or abusive email.
The four blacklists we check
| Blacklist | What it detects |
|---|---|
| Spamhaus DBL | Domains used in spam, phishing, and malware |
| SURBL | Domains appearing in spam message bodies |
| Barracuda BRBL | Domains flagged by Barracuda's reputation network |
| URIBL Black | Domains used in unsolicited bulk email |
What a blacklist hit means for you
If a domain in your list is blacklisted:
- The domain owner's mail infrastructure may be compromised or abused
- The domain itself is associated with spam activity
Sending to contacts at blacklisted domains may trigger aggressive spam filtering — your email may be blocked or junked.
What to do with blacklisted domains
For outbound prospecting: suppress these contacts or flag them for manual review. A blacklisted domain doesn't mean the individual person is bad, but the domain's reputation creates delivery risk.
Important note
Blacklist data is populated as part of Deep Analysis. Run Deep Analysis on your upload first to see Blacklist Monitor results.
