Temp mail: when a throwaway address is the wrong tool

By Alberto Gulotta · Updated 10 September 2026 · 5 min read

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.

One warning goes in the same place everywhere here. 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.

The floors listed below are being built and are not here yet, so this page names what already exists. If the reason you are here is the volume of post, how to unsubscribe, and what a sender owes you does more than any throwaway will; if you are trying to keep one address off a thread, what bcc is, and what using it costs is the page; and if the address is already on lists, the digital footprint page is where that starts.

One distinction is worth carrying up the stairs with you, because it decides which of these you want 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, an alias is the thing that fixes it, and a throwaway will only get you locked out of something later.

Not covered here. 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 everything here stays on one side of it. Where a technique has an obvious abuse, it is said 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, least of all on aliases and virtual cards, where the commissions are real and the temptation is obvious.

A last note about the reason any of this exists. Every service of this kind 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. So every page here 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. Where that question cannot be answered, the page says so instead of filling the space with the marketing copy. What holds instead is simple: every page here also states where the throwaway is the wrong answer, and none of them carries an affiliate link.
