Building unsubfa.st: inbox cleanup, done in one sweep

Open any inbox that's a few years old and you'll find the same thing: hundreds of subscriptions you never consciously agreed to. Receipts that turned into newsletters. One-time downloads that became weekly digests. The unsubscribe link is always there — buried, tiny, and ten clicks away.

I'm building unsubfa.st to delete that whole ritual.

The idea

unsubfa.st is mass email unsubscribe: connect your inbox, and it surfaces every sender that's been mailing you in one clean list. Pick what to keep, sweep the rest, and you're out — no hunting for hidden links, no opening fifty emails one at a time.

It's the same job Leave Me Alone does, rebuilt around two things I care about:

  • Fast. Scan and act in one pass. The whole point is that cleaning your inbox should take minutes, not a recurring afternoon.
  • Privacy-first. Your mail is the most sensitive data you own. unsubfa.st reads what it needs to find subscriptions and nothing more — no selling, no profiling, no quiet retention.

Why this one

I've shipped enough full-stack builds on the channel and client work at zune.one to know a good product when it annoys me daily. This one did. The category already proved people will pay to reclaim their inbox — the opening is a sharper, faster, more trustworthy take.

Building it in public

Like everything else, I'm shipping unsubfa.st in the open. The status, what works, what users actually unsubscribe from in bulk — it'll get documented here and tracked on the products page the moment there are real numbers to show.

It's in development now. If a one-sweep inbox cleanup sounds like something you'd use, that's exactly who I'm building it for.
