Frequently Asked Questions

A disposable email domain provides temporary, throwaway addresses that expire or are abandoned shortly after use. People use them to sign up for something without handing over a real inbox, which is why they cluster around free trials, promotions and one-off downloads.
Yes. imail.cool is classified as a disposable email domain in our database, based on the mail infrastructure behind it and the classification signals listed on this page.
They inflate signup numbers without producing users, distort activation and retention metrics, enable repeat free-trial abuse, and bounce later when the address expires — which damages your sender reputation.
imail.cool was first registered on 13 November 2022, which makes it 3y 9m old, older than 46% 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.
Call the MailRook API from your signup form and check the address before you create the account. You get the same classification and trust score you see on this page, in a single request, and you can decide whether to allow, challenge or block.
