If you're on Outlook or Hotmail,
your spam filter isn't broken.
It was never designed to win.

SpamSlayer is a Chrome and Firefox extension that kills spam at the source. Not one email at a time. The whole domain. One click. Done.

SpamSlayer browser extension blocking spam domains

Every morning. Same thing.

You open your inbox. Forty, fifty, sometimes sixty emails. None of them real.

Pharmacy spam. Fake order confirmations. Random domains you've never heard of.

You block one address. They're back the next day with a different one. Same domain. Different name. Same rubbish.

Microsoft's filter catches some of it. Not enough. Never enough.

You end up spending twenty minutes every morning just clearing the noise before you can get to what actually matters.

There's a better way.

I got tired of fighting it. So I built something that actually works.

I'm Ian. I've been on the same Hotmail account for years.

For a long time, the spam was unmanageable. I tried everything Microsoft offered. Nothing made a real dent.

So I built SpamSlayer.

It works differently to anything else out there. Instead of blocking individual email addresses, SpamSlayer blocks the entire sending domain. One click and every email from that source is gone. For good.

It installs in seconds, works quietly in the background, and starts cleaning your inbox from the moment you use it.

I use it on my own account every day. It changed everything.

Simple. Fast. Permanent.

Get in touch. If SpamSlayer isn't doing what it promises on your Outlook or Hotmail account, I want to know about it and I'll make it right.

Your inbox should work for you. Not against you.

Spam isn't going away. The senders get smarter, the domains change, and the filters keep falling behind.

SpamSlayer doesn't try to outsmart them. It just blocks them. Permanently.

Twenty minutes back every morning adds up to a lot over a year.
