How to Block Unwanted Emails with SpamBully

SpamBully integrates directly into your email client to keep your inbox clean and secure. Follow these steps to train the software and take control of your email:

  1. Install and Integrate
    Download the specific version of SpamBully for your email client (e.g., Office 365, Outlook, or Windows Mail). Once installed, it will automatically appear as a toolbar or ribbon menu inside your email application.
  2. Train the AI Filter
    SpamBully uses a Bayesian AI filter that learns from your actions. If a junk email makes it to your inbox, simply highlight it and click Spam on the toolbar. If a legitimate email goes to the junk folder, click Not Spam. Within a few days, accuracy will become nearly flawless.
  3. Manage Your Allow and Block Lists
    Click on the Allow / Block List settings. You can guarantee that emails from friends, family, or your address book always reach you by whitelisting them. Conversely, you can completely block specific words, entire domains, or even IP addresses from specific countries.
  4. Punish and Report Spammers
    Take action against persistent junk mail! Use the Punish or Bounce buttons to send the spam back to the sender (increasing their server costs) or automatically report them to their ISP and the FTC.
Pro Tip: Turn on the "Fraudulent Link Detection" feature in the settings. SpamBully will scan your incoming emails for phishing attempts and warn you before you accidentally click a malicious link disguised as a bank or trusted website.

Frequently Asked Questions

No. By default, messages identified as spam are moved to a designated Spam folder within your email client where you can safely review them. If you spot a good email, clicking "Not Spam" restores it to your inbox and teaches the AI not to filter it again.

Yes. Once you are confident that the Bayesian filter is accurately catching only junk mail, you can enable the Auto-Delete option in the settings. This bypasses the spam folder entirely and permanently deletes the messages.
