MXToolbox is one of the most recognized names in DNS and email diagnostics, and its paid tiers add genuine ongoing monitoring capability. But its core lookup functionality, checking what records a domain currently has, is available free through several tools, including WritoryBuzz’s own free tools. Here is an honest comparison of what you actually get at each price point.
What a Free DNS Lookup Tool Covers
Running a domain through a free dns lookup returns the domain’s current A, MX, TXT, CNAME, and other record values instantly, with no account creation or payment required, covering the core diagnostic need most site owners and administrators actually have when troubleshooting a specific issue in the moment.
What MXToolbox’s Paid Tiers Add
MXToolbox’s paid monitoring plans add ongoing, automated alerting when a domain’s records change unexpectedly or when a blacklist status shifts, a genuinely valuable capability for organizations wanting continuous oversight across many domains rather than a manual, point-in-time check performed only when a specific problem is already suspected.
| Capability | Free DNS Lookup Tool | MXToolbox Paid Tier |
| Single-domain record lookup | Yes, unlimited | Yes, included |
| Ongoing automated monitoring and alerts | No | Yes, core paid feature |
| Blacklist monitoring across many domains | No | Yes, on paid tiers |
| Typical cost | Free | Often 20 to 200+ dollars monthly |
Who Genuinely Needs the Paid Tier
IT teams and agencies managing DNS health across dozens of client domains simultaneously genuinely benefit from automated, continuous monitoring, since manually checking each domain individually at that scale would consume considerably more staff time than the subscription cost itself represents.
A single business managing its own one or two domains is frequently well served by the free tier alone, running a periodic check with a free dns lookup whenever a change is made or a problem is suspected, rather than paying for continuous monitoring a smaller domain portfolio does not genuinely require.
Building a Free-Tool Equivalent Workflow
Pairing a periodic DNS lookup with an ip lookup to confirm hosting details, and a page speed checker to rule out unrelated performance issues, covers most of what a single-domain owner genuinely needs without any recurring subscription cost.
