DuckDuckGo Email Protection is a free service that gives you a personal @duck.com address which forwards mail to your real inbox after stripping many trackers. It also generates private addresses you can disable individually. It is not a temporary inbox: the address persists until you turn it off. A disposable inbox such as MailboxTemp is random, short-lived and receive-only. The difference decides which tool suits each signup.
What DuckDuckGo Email Protection actually does
Email Protection is part of DuckDuckGo's privacy suite, alongside its search engine and browser. When you sign up, you get a main @duck.com address. You give that address to websites instead of your real one. DuckDuckGo receives the mail, strips known trackers (such as tracking pixels and some link wrappers), and forwards the cleaned message to your real email address. The service also lets you create private addresses on the fly: these are additional @duck.com addresses that forward to the same inbox and can be disabled individually.
The key point is that Email Protection is a forwarding and sanitising layer, not a mailbox. You never log in to a @duck.com inbox to read messages; everything arrives at your existing email account. DuckDuckGo does not store your messages beyond what is needed to forward them, according to its documentation, but the exact retention and logging behaviour is described in its privacy policy and can change, so check the current terms if that matters to you.
How do @duck.com forwarding and tracker stripping work?
When a sender sends to your @duck.com address, DuckDuckGo's servers receive the message. They inspect the HTML for known tracking techniques: invisible pixels, unique image URLs, and sometimes link redirects. The cleaned message is then forwarded to your real address. Because the sender only ever sees the @duck.com address, your real address is not exposed to them. If the sender later sells or leaks the address, you can disable that private address and create a new one without changing your real inbox.
Tracker stripping is best-effort. It reduces the ability of senders to see whether you opened a message, but it does not make you anonymous. The sender still knows the @duck.com address received the mail. Forwarding also means the message passes through DuckDuckGo's infrastructure, so you are trusting that provider as an intermediary. For a deeper look at how tracking pixels work, see Email Tracking Pixels Explained.
What are the one-time private addresses for?
Private addresses are the closest thing Email Protection has to a disposable address. You generate one for a specific signup, and if it starts attracting spam you disable it. They are useful for newsletters, trials, and sites you do not fully trust. But they are not temporary in the way a temp mailbox is: they persist until you delete them, and they all forward to your real inbox. That means your real inbox still accumulates the mail, even if the address is disposable.
Where Email Protection is the right choice
Email Protection is a good fit when you want a long-term alias layer over your real inbox. If you need to receive password resets, receipts, or account notifications for months or years, a persistent @duck.com address is more appropriate than a temporary inbox that expires. It is also sensible if you want tracker stripping without changing email providers.
- Long-lived accounts: shopping, utilities, or services you will keep using.
- Newsletters and marketing: you can disable the address if the sender abuses it.
- Reducing tracker exposure: the forwarding layer removes many tracking pixels before they reach you.
- Keeping one inbox: everything still arrives in your real email account, so you do not have to check a second place.
If you are weighing aliases against temporary addresses more broadly, Email Aliases vs Disposable Email sets out the trade-offs.
When is a disposable inbox better?
A disposable inbox is better when you need an address for one-time or short-lived verification and you do not want the mail to reach your real inbox at all. MailboxTemp gives you a random address that lives for 60 minutes by default, extendable in 10-minute increments; Pro inboxes last 24 hours. The service is receive-only, detects one-time codes automatically, and offers a public JSON API at /docs/ for developers. Because the address is random and temporary, there is no forwarding to your real account and nothing to clean up afterwards.
This is the right tool for:
- One-off downloads and trials where you will never need to recover the account.
- Forum or comment signups that only need a verification link once.
- Testing your own signup flows without polluting a real inbox.
- Situations where you do not want the sender to have any persistent address for you, even an alias.

Comparison: @duck.com vs a temporary inbox
| Feature | DuckDuckGo Email Protection | MailboxTemp |
|---|---|---|
| Address type | Persistent @duck.com alias | Random temporary address |
| Lifetime | Until you disable it | 60 minutes by default, extendable; 24 hours on Pro |
| Forwarding | Forwards to your real inbox | No forwarding; inbox is self-contained |
| Tracker stripping | Yes, best-effort | Not applicable (no forwarding) |
| Sending | No (receive-only forwarding) | No (receive-only) |
| Account recovery | Possible while alias is active | Not possible after expiry |
| Best for | Long-term aliasing and tracker reduction | One-time signups and verification codes |
What breaks with each approach?
Both tools have limits. With Email Protection, the main risk is that the alias is still tied to you: if you use the same @duck.com address everywhere, disabling it breaks every account that uses it. You also cannot send mail from a @duck.com address, and some sites may block forwarding domains. With a temporary inbox, the address expires, so any account that needs a later verification code, password reset, or purchase confirmation will be unrecoverable. Platforms may also block known disposable domains. For more on that, see Why Websites Block Disposable Emails.
Neither tool is a substitute for a real address on accounts that matter: banking, government, work, or anything tied to payments or identity. Use a real or alias address there, and keep two-factor authentication on. If you are unsure whether a service will need you later, a persistent alias is the safer bet; if you are certain you will never return, a temporary inbox avoids the cleanup.

In short
DuckDuckGo Email Protection is a free forwarding layer that gives you persistent @duck.com aliases and strips many trackers before mail reaches your real inbox. It is the better choice for accounts you will keep, newsletters, and reducing tracker exposure. A disposable inbox such as MailboxTemp is the better choice for one-time verification, downloads, and signups you will never need to recover, because the address expires and nothing is forwarded to your real account. Match the tool to the lifetime of the account: persistent alias for things you keep, temporary inbox for things you discard.
