I made Better Spam Filter because my inboxes were flooded with spam
Hi, I’m Rene 👋🏻 , a software developer from Austria. I created BetterSpamFilter to simplify my own life, and now I want to share it with the world. I believe this app can take the hassle out of email management for countless others too.

Community feedback
In the past, we experienced several successful phishing attacks, and I must admit that many spam emails these days look deceptively real. I implemented NoSpam in my department since we frequently receive phishing emails. What I find truly brilliant is that NoSpam also validates links within emails.

I host my email inboxes privately, but my provider’s spam filters are barely usable. NoSpam works perfectly for me!
– Personal User
With Rene and the Ultimate Plan, we successfully rolled out a company-wide implementation. Rene provided valuable consultation during the process and shared the source code with us. Thank you for the seamless collaboration!

What do I need to get started?
• IMAP credentials from your email provider (username, password, server, port, SSL).
• An OpenAI API key to enable AI-based filtering.
• A device capable of running Docker (e.g., PC, Mac, Raspberry Pi, or a cloud server).
Can I use BetterSpamFilter with any email provider?
Yes! BetterSpamFilter works with any email provider that supports IMAP. This includes popular providers like Gmail, Yahoo, Outlook, and others.
Does BetterSpamFilter delete emails?

Is it difficult to set up?
Not at all! BetterSpamFilter is designed for simplicity. With step-by-step instructions, you can set it up in minutes. The Docker container is plug-and-play, requiring minimal technical knowledge. And if you’re unsure, you can always ask your IT guy – you already talk to them about your emails anyway!
Can I customize the spam filter?
Absolutely! BetterSpamFilter allows you to fine-tune the AI filters with customizable prompts, ensuring the filtering aligns perfectly with your needs and preferences. Over time, you can adjust the prompts textually to reduce false positives and negatives, making the filtering even more accurate. No magic numbers or hidden spam filter tricks – just plain, customizable text.
