Disposable Domain is out, under Domain: each domain whose email addresses are disposable, one per row, rated high, medium or low, with the first and last day we saw it in use and the providers behind it. The November 1 build holds 25,542 domains.
One domain per row
Five rows of that build, as the file has them:
domain,first_seen,last_seen,providers,confidence
10mail.org,2023-01-08,2026-09-18,dropmail_me,high
guerrillamail.biz,2022-12-28,2026-11-01,guerrillamail_com|spam4_me,high

wwvk.store,2023-05-18,2024-05-14,tempr_email,low
first_seen and last_seen are the first and last days we saw a disposable email provider use the domain, not when it was registered. Each id in providers is a row of Disposable Domain Provider, which ships beside it with the provider's name and website, active when we track the domains it hands out now, and defunct when the provider itself is gone. It lists 92 providers, 63 of them active and 14 defunct.
Confidence
confidence says how sure we are that a domain's addresses are disposable:
| Confidence | Domains | What it means |
|---|---|---|
high | 20,982 | Certain: the one to block a signup on |
medium | 4,115 | Very likely, on indirect evidence: send it to review |
low | 445 | Weak evidence, not enough to block on alone |
Shared pools
12,562 domains have more than one provider behind them: 8,067 two, 647 three, 3,491 four and 357 five to eight. Most of it is a few sites handing out the same domains:
| Providers | Domains |
|---|---|
email_fake_com, generator_email | 4,143 |
email_fake_com, emailfake_com, generator_email, mail_temp_com | 2,488 |
temp_mail_org, tenminemail_com | 1,881 |
yopmail_com, yopmail_fr | 1,359 |
email_fake_com, generator_email, temp_mail_org, tenminemail_com | 740 |
emailfake_com, mail_temp_com | 253 |
Last seen
9,188 domains were seen in 2026, 4,440 of them in the seven days to November 1. The other 16,354 were last seen in 2024 or earlier. The file keeps every domain it has seen, and last_seen cuts whatever window a rule wants.
Random subdomains
Some providers give each inbox a random subdomain of a domain they control, and each one is a row. 8,199 rows are subdomains of three domains, cashbenties.com, crankymonkey.info and cse445.com, all seen between February and May 2024.
