Dead Disposable Email Domains: 1,821 Return NXDOMAIN

Updated 8 November 2026 · Volt Ghost team

The whole list on 8 Nov 2026

Both columns are full scans of our 9,894-domain copy of the CC0 disposable-email-domains list (snapshot 16 October 2026), queried through Cloudflare's DNS-over-HTTPS resolver with zero request errors. SERVFAIL answers swing between runs (158 on 5 November, 106 three days later, 55 of them answering normally again), so we do not count them as dead.

Old seed names and 2019 batches died most

Almost half of the 191 names first listed in 2019 are gone, and a quarter of the 2018 cohort. 2026 has the most dead names in absolute terms (636) because it is the biggest year by far, yet only 13% of it has lapsed so far. Year-level detail lives on the 2018 and 2024 pages.

The batches with the highest death rate

The tempr.email pull request is the clearest case: its title promised "active domains", and 84% of them are dead two and a half years later. The 2 June 2026 batch from several providers (#997) is already 60% gone after five months, which says more about how cheaply those names were bought than about the providers.

Endings: free and promo-priced names lapse first

The former Freenom endings (.tk, .ml, .ga, .cf) are nearly wiped out; the Freenom page explains why. .ru loses 63%, covered on the .ru page, and .cfd 83%. .com is the most durable: only 10% of listed .com names are gone. 140 dead entries sit under a second-level ending, led by co.uk (36), org.uk (26), edu.pl (23) and io.vn (14).

Three days of churn

Between the 5 November and 8 Nov 2026 scans, 32 listed domains went from resolving to NXDOMAIN (28 had already lost their MX record, 4 still had one). Over half were first listed in June 2026. In the other direction, 5 domains that did not exist on 5 November resolve again: 2 now have an MX record pointing at known temp mail servers, 2 exist without MX, and 1 points its MX at localhost (one more now answers SERVFAIL instead of NXDOMAIN). That is what re-registration looks like from the outside.

What to do with dead names

Keep them on the blocklist. An address at a dead domain cannot receive a verification code, so it fails on its own, but if someone re-registers the name it is blocked from the first sign-up. For form validation, a DNS check catches these before any list does: our email address validator reports a domain that does not exist. If a real person tells you a code never arrived, a dead or mistyped domain is one of the first things to rule out (see verification code not received). Age alone is not a death sentence, though: vomoto.com has been listed since 2015 and still publishes a working MX record.

Related DNS states: domains that exist without an MX record and domains that publish a null MX.

Check one domain

Type one address or domain to see whether it is on the list and whether its DNS still resolves. One name per query; we do not publish the dead-domain set.
