Use case · Newsletter signups

A different email for every newsletter you sign up for.

If you sign up to one. Get something free. And then they sell your address. You get to murder the alias and the spam stops. Forever.

The problem

You signed up for the lead-magnet PDF. You got the PDF. Then you got the welcome sequence, the weekly digest, the partner promotions, the partner-of-partner promotions, the re-engagement campaign because you stopped opening the partner promotions. Six months later your inbox has 47 newsletters you don't read and one you actually wanted.

What you do instead

Give every newsletter signup a throwaway alias that forwards to your real inbox. Read the welcome email. Decide whether you actually want it. If you don't, kill the alias. The newsletter has nowhere to go.

newsletter-substack-ben@you.com

Step by step

  1. Generate an alias when the signup form asks for your email.
  2. Add a one-line description so future-you remembers what it was for.
  3. Hand it over. The welcome email lands in your real inbox.
  4. If you decide you actually want the newsletter, leave the alias active.
  5. If you don't — or if they start cross-promoting nonsense — kill the alias. Spam stops. They can't reach you.

Why this works

  • Newsletter platforms (Substack, Beehiiv, ConvertKit, Mailchimp) treat the alias as a normal email. Their tracking pixels still get stripped. Their unsubscribe-then-resubscribe-when-you-buy-something tricks don't work because the address is dead.
  • When a newsletter sells your email to a partner, the partner inherits a dead address the moment you kill the alias. One click. Done.
  • If you ever want to know which newsletter leaked your address — alias names tell you. `newsletter-substack-ben@you.com` started getting unrelated marketing? Now you know.

FAQs

Will the newsletter know it's an alias?

Some platforms detect generic alias domains. Yours is custom — they see a normal address and treat it like one. Replies and forwards work fine.

What if I want to unsubscribe normally instead of killing the alias?

You can. Click unsubscribe like normal. The alias keeps working for anything legitimate. Kill it only when unsubscribing didn't actually work — which, statistically, is most of the time.
