What a burner email is
A burner, also called a temporary or disposable email, is an inbox you can use instantly without signing up. Many are public: anyone who knows or guesses the address can read what arrives. They typically expire after a few minutes, hours or days.
Burners are good at one thing: receiving a single confirmation code from a site you’ll never return to.
What an email alias is
An email alias is a permanent address that forwards to your real inbox. Only you receive what’s sent to it, and it keeps working until you stop it. If the address starts attracting spam, you switch it off.
The problems with burners for real accounts
- You lose account recovery. When the burner expires, so does your ability to reset the password. If you forget it, the account is gone.
- Anyone may be able to read it. On public burner sites, someone else can request a reset link to the same address and take over the account.
- Sites block them. Many services maintain lists of disposable-email domains and reject them at sign-up.
- You miss later messages. Receipts, refund confirmations and security alerts sent after expiry disappear.
Side by side
| Burner email | Email alias | |
|---|---|---|
| How long it lasts | Minutes to days | Until you stop it |
| Who can read it | Sometimes anyone | Only you |
| Password resets months later | No | Yes |
| Accepted at sign-up | Often blocked | Usually accepted |
| Where mail arrives | A separate website | Your normal inbox |
| Cost | Usually free | Free or low cost |
When a burner is fine
- Reading one gated article you’ll never revisit.
- A one-time code for a public Wi-Fi portal.
- Testing a form, where the content of the mail doesn’t matter.
When to use an alias instead
- Any account you might log into again.
- Shopping, where receipts, returns and warranties matter.
- Free trials you need to cancel before you’re charged.
- Newsletters and communities you actually want to read.
The bottom line
Burners trade long-term access for convenience. Aliases give you the same protection without losing your account later. Hskky aliases forward to your inbox, never expire while active, and are held for two months after you stop them in case you need them back. See plans.
