The temp mail tower · the atrium

Temp mail: the whole tower, floor by floor

This is the entrance to the temp mail tower — throwaway addresses, second numbers and disposable cards. Three different ways of not handing over the real one.

None of it is about hiding. It is about the fact that an address you gave a shop in 2019 is now on a list, the list has been sold more than once, and there is no way to take it back. A throwaway is simply a temporary email address that can be discarded when that happens, instead of one that follows you for twenty years. The tower separates the kinds, because they are not interchangeable and choosing the wrong one is how people lock themselves out of their own accounts.

Every floor carries the same warning in the same place. A throwaway address is excellent for a download, a one-off form, a shop you will never visit again — and catastrophic for anything with a recovery flow, because the day you need to prove the account is yours, the mailbox that proves it no longer exists.

Three levels, and you are on the first. The atrium lists the floors; a floor covers one kind of throwaway completely and holds the shorter guides underneath it. Nothing here is more than three clicks from the front door, and every floor comes back to this one.

One distinction is worth carrying up the stairs with you, because it decides which wing you belong in and almost nobody makes it. A throwaway is designed to die: you use it once and it takes the consequences with it. An alias is designed to live: it is a permanent address that is not your real one, it forwards everything to you, and you can switch off the single alias that started attracting spam without touching anything else. People search for the first and almost always need the second. If you are here because you are tired of the amount of rubbish arriving in your mailbox, the aliases wing is the one that fixes it, and the throwaway wing will only get you locked out of something later.

Where to start

Five ways in. The difference between the first two is the difference between ten minutes and ten years.

“I need an address for one download.”
That is a throwaway, in throwaway addresses
“I want to keep my real address off every form.”
You want an alias, in aliases that last
“I need a second phone number that is not my real one.”
That is a burner phone question, in second numbers
“I want to try a free trial without being charged.”
That is a card question, in cards and traces
“I used my real details everywhere for years.”
Start at the cleanup floors in cards and traces

Throwaway addresses

An inbox that exists for a few minutes and then is gone. One floor per service, each answering the same questions: how long it lives, who else can read it, and what happens when a site refuses it.

Aliases that last

Not throwaway at all: a permanent address that forwards to your real mailbox and can be switched off the moment it starts attracting spam. For most people this is the floor they actually needed.

Second numbers

A phone number that is not the one on your contract — for a marketplace listing, for a form that demands one, for a country you do not live in. The rules here are stricter than for email.

What this tower will not do

It will not help anybody deceive a person. There is a clear line between refusing to give a shop a permanent address and pretending to be somebody you are not, and every floor here stays on one side of it. Where a technique has an obvious abuse, the floor says so plainly instead of pretending not to notice.

It will not tell you to route your important accounts through a disposable address. That advice circulates constantly and it is how people lose mailboxes permanently. The tower repeats the opposite so often that it will become annoying, which is the intention.

And it will not carry affiliate links, including on the alias and virtual card floors, where the commissions are real and the temptation is obvious.

A last note about the reason any of this exists. Every service on these floors is a business, and a business that stands between you and your post has to be chosen more carefully than a shopping decision usually is. An alias provider sees every message forwarded to you. A burner number app sees who calls. A virtual card sits between your bank and the merchant. Each floor therefore says the same thing in the same place: who is in the middle, what they publish about what they keep, and the date we read it. If a floor cannot answer that question, it says so instead of filling the space with the marketing copy. What holds instead is simple: every floor also states where the throwaway is the wrong answer, and no floor carries an affiliate link.
