They sound the same. They aren't.
Both let you avoid spraying your real email everywhere, so people lump them together — but they solve opposite problems. Pick the wrong one and you'll either lose access to something you needed, or keep getting mail you wanted gone. Here's the clean distinction.
Temporary (disposable) email
A throwaway inbox that exists for a few minutes and then auto-deletes itself. There's no login, no password, and no recovery — once it's gone, it's gone, along with anything sent to it.
- Best for: one-off signups, grabbing a single verification code, claiming a trial, downloading a "free" PDF, testing your own app.
- Strength: maximum anonymity — it was never tied to you and leaves no trace.
- Limit: you can't receive anything later. No future receipts, no password resets, no "we've updated our terms" — and no way back into the account if it depended on that inbox.
Email alias
A permanent forwarding address — something like shop123@yourdomain — that quietly delivers to your real inbox. You can create many, label them per service, and switch any one off if it starts attracting spam.
- Best for: accounts you intend to keep — shopping, newsletters you actually read, services that send receipts or resets.
- Strength: control. You still get the mail, you know exactly who leaked your address (the alias they had), and you can kill that one alias without affecting the rest.
- Limit: it still routes to your real inbox, so it's not anonymous — it's organised. And setting it up usually needs your own domain or an alias provider.
The simple rule for choosing
Will you ever need to receive mail here again?
If no → temporary email. If yes → alias.
That single question settles almost every case. Signing up to read one gated article? Temp mail. Creating a shopping account you'll order from again? Alias. Verifying a throwaway forum login? Temp mail. Registering software you'll need to reset the password for? Alias.
A quick side-by-side
- Lifespan — Temp: minutes, then deleted. Alias: permanent until you remove it.
- Recovery — Temp: none. Alias: full (it's your real inbox behind it).
- Anonymity — Temp: high. Alias: low (organised, not hidden).
- Setup — Temp: instant, no account. Alias: needs a domain or alias service.
- Spam control — Temp: irrelevant (it's gone). Alias: excellent (disable the leaky one).
You can use both
They're not rivals — most privacy-minded people use temp mail for the disposable 80% of signups and aliases for the handful of accounts that matter. PrivySuite's temporary email covers the throwaway side instantly and with no account; reach for an alias only when you genuinely need the mail to keep arriving.

FAQ
What is the difference between a temporary email and an email alias?
A temporary email is a throwaway inbox that auto-deletes with no recovery; an alias is a permanent forwarding address that delivers to your real inbox and can be switched off later. Temp mail is for one-off signups; aliases are for accounts you keep.
Can I receive ongoing email with a temporary address?
No — a temporary inbox is built to expire, so anything sent after it lapses is lost. For ongoing mail like receipts or resets, use an alias that forwards to your real inbox.
Is a temporary email or an alias more private?
Temp mail is more anonymous (not linked to you, then deleted). An alias is more manageable (keep, mute, or kill it) but still routes to your real inbox. Choose anonymity or control based on the situation.
