Where MXToolbox still has the edge
What HostRepute does not do yet
Honest gaps, listed up front. Each one is in the public roadmap with a quarterly target so you can plan around it.
See the full feature catalogue-
Network intelligence remains lightweight
Future expansionHostRepute now ships SuperTool and standalone ASN/IP lookup. MXToolbox still has a broader legacy diagnostics surface, so the next pass should deepen incident-level network context.
-
No provider-side delisting automation
Deferred intentionallyHostRepute now ships curated removal metadata plus assisted attempt logging from listed results. It opens provider URLs or email drafts and tracks status, but does not submit provider forms server-side.
-
Status pages start on Business+
Available nowHosted public status pages are available for Business and Enterprise teams. Smaller teams should use noindex public reports until they need subscriber updates.
