AcuityScan vs MXToolbox

MXToolbox is the go-to for email and DNS lookups. AcuityScan runs those same checks and seven more categories in one scan, with a unified score and a copy-paste fix for every finding.

MXToolbox has been the reference tool for email and DNS diagnostics for over two decades. Its blacklist monitoring and SuperTool lookups are excellent, and if email deliverability is the only thing you care about, it does that job well. AcuityScan is built for the broader question: is this whole website healthy, not just its mail records.

When MXToolbox is the better choice

We would rather you pick the right tool than the wrong one. MXToolbox is the better fit when:

You only ever need email and DNS lookups and already know the records cold.
You rely on a specific MXToolbox feature like its long-running blacklist delisting workflow.
You want the deepest possible single-purpose email tooling and nothing else.

Questions

Does AcuityScan check the same blacklists as MXToolbox?

AcuityScan queries 80+ live, verified email blacklists (RBLs), including the major ones MXToolbox uses such as Spamhaus, SpamCop, and Barracuda. We removed dead and unreliable lists rather than padding the count.

Is AcuityScan cheaper than MXToolbox?

AcuityScan's paid tier starts at $29/mo and includes monitoring across all 8 categories. MXToolbox monitoring starts at $129/mo as of 2026 and focuses on email and DNS. Pricing changes, so check both current pages before deciding.

Can I still do a one-off email lookup without a full scan?

Yes. AcuityScan has standalone tools, including an email health check, blacklist check, and DNS lookup, that work without an account, the same way you'd use MXToolbox's SuperTool.
