MxToolbox is a lookup tool.
DNSSnuff is a diagnostic tool.
MxToolbox is built around individual lookups — you choose which record to check, it shows you the raw result. It's powerful if you know exactly what you're looking for and can interpret the output.
DNSSnuff runs all 72 checks automatically and tells you what the results mean. One report covers everything — you don't need to check SPF, DMARC, MX records, and DNSSEC separately.
When MxToolbox makes sense:
- You need to check a specific record type quickly
- You're comfortable reading raw DNS data
- You need extensive blacklist lookup capabilities specifically
When DNSSnuff makes sense:
- You want a complete diagnostic in one report
- You need plain-English explanations of what's wrong and how to fix it
- You're managing multiple domains and want monitoring with change alerts
- You're an MSP who needs white-label reports for clients
