Four kinds of “fake email”, and which one you need
The same phrase is used for tools that do fundamentally different things. Picking the wrong kind is the most common reason something “does not work” — the tool was never meant to do what was being asked of it.
The four kinds
| Kind | Can it receive mail? | What it is for |
|---|---|---|
| Address maker | no | producing realistic-looking strings for test data |
| Disposable inbox (this site) | yes | receiving a code or a link without giving out your own address |
| Forwarding alias | yes, into your real inbox | a permanent address that hides your real one |
| Developer sandbox | yes, via an API | automated tests of sign-up flows |
Address makers: the one that catches people out
A “maker” or “creator” that produces a list of plausible addresses is generating strings. Nothing was created anywhere; no mailbox exists; nothing sent to those addresses arrives anywhere.
They are genuinely right for one job: filling a test database with realistic values, where nothing will ever be sent.
Disposable inbox
A real mailbox, instantly, with no account — the thing this site does. Right when you need to receive something once and then stop caring. Wrong when you need the address to still work next year, because it expires by design.
Forwarding alias
An address that quietly forwards into a mailbox you already own. Right when you want the mail permanently but not your name on it: newsletters, shops, anything you may want to switch off later without changing your real address.
The trade is the opposite of a disposable inbox: it is permanent, and it is tied to an account you registered. It hides your address from the sender; it does not detach the address from you.
Developer sandbox
An inbox reachable by API so a test suite can read what the application sent. Right for automated testing; heavy-handed for a single sign-up, since it needs an account and a key. What is worth knowing if that is your case — testing sign-up flows.
Choosing by what you are actually doing
| You need to… | Use |
|---|---|
| get a code once and never return | disposable inbox |
| keep receiving, but not expose your address | forwarding alias |
| fill a test database | address maker |
| read mail from a test script | developer sandbox |
| keep an address that is not tied to you | disposable inbox on your own domain |
The last row is the combination people usually want without knowing it exists: no account, no connection to you, and it lasts as long as the domain registration does.
What none of them can do
Send mail as somebody else. Forging a sender is a different activity with a different name, and it is not what any of these tools are — including the ones whose marketing gets close to implying it.
