There are several ways to avoid giving your real email address to every website. They sound similar, but they solve different problems. Here is a clear comparison so you can pick the right tool each time.
The four options at a glance
| Feature | Temporary email | Email alias (forwarding) | Plus addressing (you+shop@) |
Burner account |
|---|---|---|---|---|
| Set-up time | Seconds | Minutes (one-time set-up) | None | 10+ minutes |
| Needs an account | No | Yes | No (uses your email) | Yes, often with a phone number |
| Hides your real address | Yes | Yes | No, your address is visible | Yes |
| Lifetime | Minutes to days | Until you disable it | Same as your inbox | Until you abandon it |
| Can reply and send | Some services | Usually yes | Yes | Yes |
| Best for | One-time and short-term use | Long-term accounts you want to keep | Filtering, not privacy | Separate online identity |
Temporary email
A temporary email is a ready-made inbox that deletes itself after a set time. No account, no personal data, nothing to manage. (What is a temporary email?)
Choose it when: you need an address now, for something short-lived: sign-ups, trials, codes, downloads, a seller’s reply.
Avoid it when: you will need the account later, for example to reset a password months from now.
Email alias (forwarding address)
An alias is a separate address that forwards emails to your real inbox. You create a different alias for each website. If one starts sending spam, you turn that alias off.
Choose it when: you want to keep an account for a long time, but still hide your real address and be able to cut off a leaking site.
Downsides: you need to sign up for an alias service and trust it with all your forwarded mail. Emails still end up in your personal inbox.
Plus addressing ([email protected])
Many email providers ignore everything after a + sign, so yourname+shop@… still reaches yourname@…. It is useful for filtering emails into folders and spotting which site leaked your address.
The catch: it is not private. Anyone can remove the +shop part and see your real address, and spammers do exactly that. Some websites also reject addresses with a +.
Burner account
A burner is a full, regular email account (for example a free webmail account) created only to keep away from your main identity.
Choose it when: you need a separate long-term identity, such as for a side project.
Downsides: it takes time to create, many providers require a phone number, and you have to remember another password and check another inbox.
Which one should you use? A quick decision guide
- “I need a code or a confirmation right now.” → Temporary email.
- “I’m trying a service for a week and may cancel.” → Temporary email with a duration of a few days.
- “I’m selling something and need to talk to buyers.” → Email alias, so you can reply without showing your real address.
- “I’ll use this account for years.” → Email alias, or your real email.
- “I want to sort my emails into folders.” → Plus addressing.
- “I need a separate online identity.” → Burner account.
Can I combine them?
Yes, and many privacy-conscious people do. A common setup is:
- Real email for bank, work, family and health.
- Aliases for long-term online accounts.
- Temporary email for everything quick and disposable.
This keeps your real inbox almost spam-free and limits the damage when any single website is breached.
Summary
Temporary email wins on speed and zero commitment. Aliases win for long-term accounts. Plus addressing is for organizing, not hiding. Burner accounts are for separate identities. Pick the tool by how long you will need the address.
