Disposable email database
5,440 disposable email
domains, tracked daily.

Type any domain — we check it against the live blocklist.

02 — Browse by letter
All 5,440 domains, alphabetised.

Don’t maintain a 5,000-line file. Call the API.
TrueUser ships this list (and a dozen other signals) behind one REST endpoint. Drop it into your signup handler and reject disposable, role, and batch-cluster addresses before they cost you onboarding spend.
