An alias is a real address that forwards to the inbox you already use, so you can give services an address without handing out your main one.
01What an alias does
Every account you open starts the same way: hand over your email address. From then on, that address sits in databases you can't see, gets merged, sold, leaked and spammed. And it's the same address your bank uses.
An alias breaks that habit. It's a real, working address that receives mail and forwards it to the inbox you already read. The sender only ever deals with the alias.
02Common uses
The pattern is always the same: somewhere asks for an email address, and you decide how much of yourself to hand over. An alias makes the cheap answer the safe one.

03Alias vs. temp mail
Public disposable-email sites hand you a shared, short-lived inbox: mail often expires quickly, and on some of them anyone who knows the address can read it. That solves a different problem. An alias is a lasting address that's yours to keep using, and mail arrives in your own inbox, in your own mail app, next to everything else.
| Disposable temp mail | AxelAlias alias | |
|---|---|---|
| Lifespan | Often expires quickly, along with everything in it. | A lasting address that stays yours to keep using. |
| Who can read it | On public services, often anyone who knows the address. | Mail forwards to your own inbox. |
| Where mail lands | A separate web inbox you have to check. | Your existing inbox, in the mail app you already use. |
| Receipts and resets | Short history; a bad place for a password reset you'll need later. | They stay findable with the rest of your mail. |
| Purpose | Getting past a form once. | Giving every service a reachable address that isn't your main one. |
04Principles
It's the key to your bank, your resets and your identity online. The fewer databases it sits in, the better, so hand out aliases and keep the original close.
Unsubscribing asks the list that spammed you for permission. Dropping an alias asks no one anything. Where the setup lets you disable the address, the noise stops with it.
Unlike a burner inbox, mail to an alias lands in your own mailbox, so your history stays with you. A password reset from three years ago is still right where it landed.
An alias draws a line between services and your identity: honest compartmentalisation, not a promise of anonymity. It's hygiene, and hygiene is enough.
05FAQ
No. Disposable email is a short-lived shared inbox; an alias is a lasting address that forwards to your real inbox. One is built to vanish, the other is built to keep. And if an alias turns bad, that's the address you stop using, not your inbox.
No, and that's the point of forwarding. Aliases deliver to the inbox you already have, whatever provider it lives at. Nothing new to check, nothing new to log into.
With aliasing in general you can disable that one alias at the forwarding layer. Because each service had its own address, you can tell where the spam came from, everything else keeps working, and your main inbox is out of the line of fire.
With aliasing in general, replies can go back out through the alias, so the thread only shows the address the other side already knew. How replies are handled in practice depends on the alias setup.
Plus-addressing still contains your real address. Anyone can strip the tag and mail you directly, and plenty of forms reject it outright. A separate alias shares nothing about the address behind it.
No, and it's not meant to. An alias separates services from your main address; it doesn't hide who you are. Think compartmentalisation: honest, useful, and not a disguise.
