Can Hubi check any domain, or only ones I own?

MXToolbox lookups are public diagnostics, so Hubi can run blacklist, DNS, and MX checks on any domain or IP you name. You do not need to control the domain to inspect its public records.

What does Hubi actually see with my API key?

It uses the key to run the lookup endpoints your plan exposes and read the results back. It does not change any settings on the domains it inspects, since these are read-only diagnostic queries.

Can Hubi monitor a domain continuously?

Hubi runs a check whenever you ask, and you can pair it with a scheduled instruction or a triggering event so it re-runs a blacklist or DNS lookup and flags you only when something changes.

Can Hubi push results into another tool?

Yes. Once both are connected you can chain MXToolbox with Slack, a ticketing tool, or a spreadsheet, so a failed lookup turns into a posted alert or a logged row in one instruction.

All Integrations

MXToolbox

IT Operations Server Monitoring

When email stops landing or a domain looks shaky, you usually end up running blacklist, DNS, and MX lookups one tab at a time. Hubi calls MXToolbox to run those diagnostics on request - checking blacklists, resolving DNS records, testing mail flow, and reporting what is broken so you can stop copy-pasting hostnames into a form.
