Signals, not verdicts. A domain appears here because heuristics matched its name, its infrastructure or the page it served on its first day. Where a model has looked at it, that is shown as an opinion with a confidence, not as a finding. Nothing on this page says a site is malicious. Read the evidence and decide for yourself.

What matched
Model opinions
SenderOwner is a legitimate third-party tool for Microsoft 365 MSPs/CSPs to analyze and plan sender migrations. The page clearly states 'No account. No Microsoft credentials' and explicitly disclaims that it 'does not connect to the tenant or execute the migration'—the opposite of phishing behavior. The domain name matches the product brand, there is no login form, and the content is educational/functional software, not credential harvesting.
A model looked at the screenshot and page text and wrote what it thought. It can be wrong, and it is not a finding.
