Disposable Email Domains First Listed in 2018 (2,866)

Updated 7 November 2026 · Volt Ghost team

Where 2018's domains stand today

We read each domain's MX through Cloudflare's DNS-over-HTTPS resolver on 5 November 2026 (full-list scan of our 9,894-domain copy; 0 errors). First-listed dates come from the public Git history of the disposable-email-domains project that our disposable domains list copies. A domain counts for 2018 if that is the year it first appeared in the list file.

Almost everything arrived on day one

2,832 of the 2,866 were listed in October 2018, and 2,828 of those came from the seed commit titled "use neutral language for naming and describing assets in this repo". Later 2018 changes added only a few dozen more names. 127 2018 names have since been removed upstream and are not in our checker.

Where the surviving 2018 domains deliver mail

Many early listed domains never ran their own mail brand. On 5 Nov 2026 their MX pointed at a mix of shared temp-mail hosts, general forwarders and parking MX. Linked rows have a dedicated page.

243 still point at mail.casadorock.com (an older shared host not yet given its own mail-server page), and 91 at Mailinator. Forwarding and parking are common too: Google Workspace MX, Cloudflare Email Routing, Mailgun and Above.com all appear. That mix is why an MX fingerprint alone is a weak disposable signal — see how sites detect disposable email.

Top-level domains in the 2018 cohort

320 of these names use a Freenom ending (.tk, .ml, .ga, .cf, .gq); most of those are gone today, which is covered on the Freenom endings page. .com still leads overall.

What this means if you block temp mail

A blocklist that only tracks 2025–2026 additions will miss nearly a third of today's list. The 2018 cohort is the backbone of every public disposable list, and many of those names still resolve. Refresh the list, then use MX only as context. If you are deciding whether using these addresses is allowed at all, read is disposable email legal?.

Year roll-ups for later waves: 2024 (219), 2025 (1,161) and 2026 (4,925 in our copy).

Why the seed still matters in 2026

Blocklists that only ingest pull requests from the last year quietly drop the 2018 backbone. Attackers and testers still reuse those names because they are already trusted by some filters as "old". Treat first-listed year as a freshness signal for your copy of the list, not as permission to ignore anything older than a calendar year.
