Why the hell have we spent 30 years digging through email threads to find a damn PDF?

PostFach just shows you your attachments — straight up, like a folder. Last 30 days, newest first. No guessing subject lines, no opening emails, no thinking. It’s what email should’ve done all along - oh and if you still can't find your attachment, our search is second to none.

Get early access to the attachment stream that changes everything.

Today

Final approval needed for launch

The marketing materials look fantastic! I've reviewed everything and we're ready to proceed with the launch. Just need your final sign-off on the pricing strategy we discussed last week.

Yesterday

Marketing campaign feedback

I love the creative direction we're taking! The visual identity is spot on and really captures our brand essence. A few minor suggestions: could we make the CTA button more prominent and maybe adjust the color palette slightly?

Last Week

Budget allocation for Q1

After reviewing the quarterly projections, I think we should allocate more budget to digital marketing. The ROI has been consistently strong and we're seeing great traction in the 25-34 demographic.

Team meeting notes and action items

Thanks for leading such a productive meeting today. I've compiled all the action items and next steps. The timeline looks aggressive but achievable if we stay focused on our priorities.

Last Month

Welcome to the marketing team!

Welcome aboard! I'm excited to have you join our marketing team. You'll be working closely with the design and product teams to launch our biggest campaign yet. Let me know if you have any questions as you get settled in.

Project kickoff discussion

Great to connect! I'm looking forward to collaborating on this exciting new project. The initial concepts look promising and I think we can create something really impactful together.

Threads break. Subjects change. People get added (and removed). But your connection with a person stays the same.

PostFach shows every email you’ve ever sent or received from one person — in one clear, chronological timeline. No confusing threads, no endless searching through subject lines. Just a simple, honest view of your conversation history.

Finally, email that works the way relationships do.

Sign up now to try the timeline that finally gets people, not threads.

🙋🏻‍♂️ The 10 PostFach Promises — From Me to You

  • 1. PostFach is build by a Human

    Hi, I'm Peter, great to meet you! Just to let you know: I'm not some major corporation. I’m just a guy up his attic building something I love using every day.

  • 2. No subscriptions. One-time purchase. Forever yours.

    I hate subscriptions too. This is my app, and once you buy it, it’s all yours—no strings attached.

  • 3. Your inbox stays yours. No data collection, no selling.

    I don’t peek or share — what’s in your inbox is just between you and your mail.

  • 4. No ads — just focus

    Email’s for getting things done, not for bombarding you with ads or distractions.

  • 5. No venture capital — just passion

    This isn’t about growth at any cost. It’s a labor of love, funded by people who care.

  • 6. I'll be honest when I need your help

    If funds run low, I’ll ask for your support openly — no paywalls, no ads, just a straightforward ask. If it works for Wikipedia, it will work for me.

  • 7No AI spying on your emails

    Your emails aren’t data for AI experiments. I don’t scan or analyze them. If this is a feature you like then I'll be the first to recommend using SuperHuman

  • 8. Simple by design

    PostFach focuses on doing a few things really well — no overcomplicated features to slow you down.
