Corporate domain report: proactive.jp
proactive.jp is an established corporate domain operated by an organisation, with proper MX configuration and no risk signals. Addresses on this domain are safe to allow in registration flows, lead capture, and any other place where you'd accept a known-good email.
The domain has been registered for many years, uses a reputable mail provider, and does not appear on any of riskmail.io's risk lists. Our recommendation is allow. You don't need any additional verification beyond the standard email-confirmation step you'd run for any other corporate address.
Signals & methodology
A clean verdict is not just the absence of red flags; it is the convergence of several positive signals. The domain has a stable MX record set, no overlap with the throwaway registries we monitor, and a mail provider that publishes both SPF and DKIM. Reputation is recomputed on every lookup, so if any of those positive signals were to change tomorrow, the response would change with them — there is no manual list of "blessed" domains that goes stale over time.
How to handle this in your product
Treat the allow response as confirmation that the domain class is fine, not as a substitute for the email-confirmation step you already run. Capture the verdict alongside the user record so it's available for downstream fraud scoring; if the domain ever gets flagged later, you'll already know which existing accounts came from it. For B2B funnels, the signal that this is a corporate domain (rather than a free webmail address) is also useful for routing the lead to a different sales workflow.
