Comparison
NukeMail's persistent inbox is a different bet on what "disposable" means. If you want an address that genuinely disappears — no access code, no 24-hour storage — here's how the two compare.
Feature Comparison
Why Switch
NukeMail generates a 6-digit access code you need to save in order to retrieve your inbox later. FastTempMail skips that entirely — open the app and your address is ready. Nothing to write down, nothing to lose.
NukeMail's 24-hour inbox persists across sessions by design — which means your messages are sitting on their servers long after you've moved on. FastTempMail deletes the address and every message the moment the session expires, with no backups kept.
Running parallel tests or comparing two sign-up flows? FastTempMail lets you manage up to 3 active disposable addresses in a single tabbed session. NukeMail gives you one inbox per access code.
NukeMail defaults to a fixed 24-hour window. FastTempMail defaults to 6 hours — shorter by design, better for privacy — and lets you extend up to 3 days when a longer window is genuinely needed.
Verdict
NukeMail's persistent inbox is useful if you need to come back to the same address hours later — but that persistence is exactly what makes it less private. A 24-hour inbox stored behind an access code is not really throwaway; it's just a lightweight account.
FastTempMail is built for the opposite use case: use it, get what you need, and have it disappear automatically. No code to save, no server-side data after expiry, and up to 3 parallel addresses if your workflow needs them. If the smallest possible footprint is the goal, FastTempMail is the sharper tool.
