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. 509.lol 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.
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.
