SpamSlayer extension showing blocked spam senders and stats
I spent years fighting spam. In the end, I built the weapon I wished I'd always had.

If you use Outlook or Hotmail, you already know the pain. Every day, the same garbage floods your inbox — fake prize notifications, phishing emails pretending to be Amazon, pharmacy spam, and offers from domains you've never heard of. You block one address and the next day they're back with a different one from the same domain.

I tried everything. Outlook's built-in filters? Useless — the same senders sail right through. Manually blocking addresses one by one? A full-time job. Reporting phishing? Microsoft doesn't seem to care. I'd spend 20 minutes every morning just clearing out junk before I could even see my real emails.

After years of frustration, I decided to build what Microsoft wouldn't. SpamSlayer is the tool I wished had existed. It sits right inside your Outlook inbox, scans every email, and gives you one-click power to delete, block entire domains, report phishing, and even bounce fake delivery notifications back to spammers. It learns what you block and gets smarter every day.

Now my inbox is clean. Yours can be too.

Your Inbox, Your Rules

🛡️

Block Entire Domains, Not Just Addresses

Spammers use dozens of addresses from the same domain. SpamSlayer blocks the whole domain in one click — every address, current and future.

Auto-Destroy High-Confidence Spam

Obvious spam gets deleted automatically before you even see it. SpamSlayer scores every email and removes the worst offenders instantly.

🧠

It Learns From You

Every email you block teaches SpamSlayer what to catch. Your personal spam filter gets smarter with every click, adapting to the junk targeting your inbox.

Frequently Asked

SpamSlayer works with any Outlook Web account — whether it's a personal Hotmail, Outlook.com, or Office 365 account. If you access your email through the browser at outlook.live.com or outlook.office.com, SpamSlayer will work.
SpamSlayer can't prevent emails from reaching your inbox — only Microsoft's servers can do that (and they're not great at it). What SpamSlayer does is scan your inbox the moment you open it and automatically delete spam before you have to deal with it. Once you block a domain, every future email from that domain is auto-deleted on sight. After a few days of use, your blocklist grows and most spam disappears the instant it arrives. You'll barely notice it.
SpamSlayer only auto-deletes emails that score extremely high on its spam detection (70+/100). Medium-confidence emails are flagged for your review with action buttons — you decide what to do with them. You can also whitelist any sender or domain with one click to make sure they're never flagged.
No. You pay once, you own it forever. There are no recurring charges, no trial periods that auto-renew, and no upsells. The price you see is the price you pay, and you'll receive every future update at no extra cost.
After purchasing, you'll receive a license key and a link to install from the Chrome Web Store. Click "Add to Chrome" (one click), then open the extension and paste your key. The whole process takes under 60 seconds.
Yes! Microsoft Edge supports Chrome extensions natively. You can install SpamSlayer from the Chrome Web Store and it works perfectly in Edge.
We offer a 30-day money-back guarantee, no questions asked. If SpamSlayer isn't working for you, email support@xtoolstack.com and we'll refund you immediately.
Each license works on one browser at a time. If you switch to a new computer, just enter the same license key — it will automatically transfer. No need to contact support.
