One address per publisher makes unsubscribing optional. Newsletters are the easiest place to start with aliases: the stakes are low, nothing breaks if you get it wrong, and the payoff is immediate — a publisher who sells your address to a marketing group identifies themselves, and you end it in one action rather than working through an unsubscribe form you don't trust.
Why newsletters are the ideal starting point
If you're unsure whether an alias system suits you, test it here first. Nothing depends on a newsletter address: no password reset you'll need in three years, no delivery notice, no refund. If you disable one by mistake the cost is that you stop receiving a newsletter, which was the likely destination anyway.
That makes it a low-risk way to learn the habit before applying it to accounts that matter.
The setup
- One address per publisher, named after them:
morningbrew@yourdomain.com, notnewsletters@yourdomain.com. A single shared newsletter address works for filtering but destroys attribution — you'd know a newsletter leaked you, not which one. - Filter on the address, not the sender. Route everything at these aliases into a reading folder so newsletters never touch your inbox.
- Read on your schedule. The folder is the point: newsletters stop being interruptions.
- Bored? Disable the alias. No unsubscribe form, no "are you sure", no confirmation email.
- Mail from someone else at that alias? That publisher passed you on. Now you know, and you can act on it.
The category-address mistake
It's the obvious first instinct and it costs you the main benefit. With newsletters@yourdomain.com you can filter, but when marketing mail starts arriving there you're back to guessing which of your twenty subscriptions sold you.
Per-publisher addresses cost nothing extra with a catch-all setup — you type a different word before the @ — and they preserve attribution completely. Naming conventions.
What it exposes
Newsletter publishers vary enormously in how they treat subscriber lists, and there's no way to tell from the outside. Some never share. Some sell. Some are acquired by companies with different views. Some use a marketing platform that's breached.
Per-publisher aliases turn that from an unknowable into an observation. Within a year you'll know which of your subscriptions is a good citizen — and the ones that aren't are switched off with no negotiation.
Unsubscribing still has a place
For a publisher you genuinely like that's simply sending too often, unsubscribe properly rather than disabling. It's legally backed, and it tells them something useful. Disabling is for when you're done with them, or when they've passed you on. When unsubscribing works.
The one thing to watch
Some newsletters are attached to an account — a publication with a paid subscription, say. If so, that address is doing double duty: it receives the newsletter and it's your login and password-reset route. Treat it like an account address rather than a newsletter address, and don't disable it while the subscription is live. Avoiding lockouts.
