Frequently Asked Questions

izumi.systems is not currently classified as a disposable email domain in our database. The trust signals on this page show what we did find — a domain can still be low-trust without being a known throwaway service.

It is a 0–100 summary of everything we know about the domain: whether it runs a real website, how old it is, who registered it, which mail servers it uses, whether it sits on infrastructure shared with known throwaway services, and how its domain ending scores for abuse. Every signal that moved the number is listed on this page.

izumi.systems was first registered on 17 September 2023, which makes it 2y 11m old, older than 42% of the domains in our catalogue. Registration dates come from the domain's WHOIS/RDAP record.

Age is a cost signal. Setting up throwaway infrastructure is cheap, but waiting years is not, so domains registered in the last few weeks are heavily over-represented in disposable signups, phishing and short-lived spam runs. It works in one direction only: a new domain is a reason to look closer, while an old domain is a weak positive rather than a guarantee — expired domains get bought and repurposed precisely because their age looks reassuring.
