Different Tools, Different Focus
MXToolbox: The Swiss Army Knife
MXToolbox offers many email-related tools:
- Blacklist lookup
- MX record lookup
- DNS diagnostics
- SMTP testing
- Header analysis
- And dozens more
It's a comprehensive toolkit for email administrators who need various diagnostic capabilities.
Email Blacklist Checker: Focused on What Matters
Email Blacklist Checker concentrates on blacklist status and email deliverability:
- Blacklist checking for IPs and domains
- Focus on blacklists that actually impact delivery
- Integrated with authentication tools (SPF, DKIM, DMARC)
- Part of a cohesive deliverability monitoring suite
The focus means simpler workflows for deliverability-specific needs.
Blacklist Coverage: Quality vs Quantity
The List Count Trap
Some services advertise checking "100+ blacklists" or similar large numbers. But does this matter?
Many blacklists are obscure: Rarely used by major email providers.
Some are defunct: No longer maintained or queried.
Impact varies wildly: Spamhaus affects everyone; some lists affect almost no one.
Checking more lists isn't automatically better.
What Actually Affects Delivery
Blacklists that matter most:
- Spamhaus (SBL, XBL, PBL, DBL): Universally checked
- Barracuda: Common in enterprise
- SpamCop: Moderate impact
- Major provider lists: Google, Microsoft internal lists
Being listed on an obscure blacklist with 100 users means nothing. Being listed on Spamhaus means significant delivery problems.
Our Approach
Email Blacklist Checker focuses on:
- Blacklists that actually impact deliverability
- Both IP and domain blacklists
- Lists used by major email providers
- Actionable results, not noise
Continuous Monitoring
Why One-Time Checks Aren't Enough
Both tools offer one-time lookups. But blacklist status changes:
- You could be listed tomorrow
- A listing could expire
- New issues could emerge
- Without monitoring, you discover problems too late

- Monitor multiple assets
- Email alerts on changes
- Part of broader monitoring package
- Bundled with other MXToolbox features
