I'm a disorganized person. I've made my peace with that in most corners of my life, but email is the one place where being disorganized quietly costs other people something: the supplier who didn't get paid on time, the form that needed signing last week, the accountant asking, again, for the receipt I swore I'd already sent.
For years I tried to fix this the way everyone tries to fix it. With apps. I've used a lot of them. Inbox zero this, a folder system that, a method with its own manifesto and a paid course attached.
And here's the strange part: they all worked. For about two weeks. There's a honeymoon at the start of every new productivity app where you feel like a different person, finally on top of it all. Then the willpower the whole thing was quietly running on runs low, the system turns into one more thing you have to maintain, and you slide back to exactly where you were. Except now you also feel a little guilty every time you see the app's icon.
After enough rounds of that I stopped blaming myself and started looking at the tools. I noticed something none of them would admit: not one of them was actually nice to use. Efficient, maybe. Clever, occasionally. But using them felt like flossing, something you do because you're supposed to, running entirely on discipline. The second your discipline dipped, the whole thing fell over. Of course it did. Nobody can power a daily habit on willpower forever.
Campbooks didn't begin as a grand answer to any of this. It began as something much smaller and much more boring.
I run a small consultancy. We don't have many clients, but we have an absurd number of tiny expenses. The subscriptions, the coffees, the train tickets, the twelve-euro invoices that each take five minutes and a flicker of willpower to file correctly. Every month our accountant needed all of it, in order. And every month, getting it to them correctly was a low, persistent pain that never quite went away.
So I built a thing to kill that one pain. One job: take the stuff landing in our inbox and turn it into paperwork our accountant could actually use. I wanted it narrow on purpose. No vision, no platform. Just the single annoyance, finally handled.
I ran into the problem every side project has. I was enjoying myself too much. I'd finish the thing I'd set out to build and think, well, while I'm in here. One more feature. Then one more.
The narrow little tool kept wanting to be wider, and I kept letting it, because (and this surprised me) building it felt good in a way that doing email never had. Somewhere along the line it quietly stopped being a receipts tool and became an email client. I didn't sit down and decide that. It just happened, and I went with it.
The fun turned out to be the clue. The thing I kept circling back to was this: in all the years of email, across all the clients and apps and grand reinventions, I'm not sure anyone has ever really tried to make managing it feel good. Faster, yes. Tidier, sure. Smarter, lately. But stimulating? Something you might actually look forward to opening? That box has sat there unticked the whole time. And I've come to think it's the only box that ever mattered.
I'm not going to insult you and call email fun. Email isn't fun. But dealing with it doesn't have to feel like a small punishment, and I'm convinced it can be close to the opposite. Something with a bit of momentum and a bit of satisfaction to it, where clearing what's in front of you has more in common with a good game than a bad chore. Not calm, exactly; calm is what you get to feel afterward. I mean engaged while you're actually in there.
That's the whole bet behind Campbooks. If the inbox sorts itself (reads what comes in, files the invoices and receipts and contracts on its own, and hands you a short list of what actually needs you), then the part that's left over can be the good part. And if the good part is genuinely pleasant to do, you'll keep doing it. Not because you've discovered some hidden reserve of discipline, but because you no longer need one.
That's the trick every other tool missed: the way to make a habit stick isn't to demand more willpower from people, it's to build something that asks for less.
Once your inbox is somewhere you don't mind being, it can start giving you more back. The paperwork is already there, sorted and searchable. Scout can brief you on what arrived and draft the replies you'd rather not write, for you to send or bin. Your calendar, your documents, your little automations: all of it in the place you were heading anyway. The inbox stops being the thing standing between you and your work, and starts being where a good chunk of the work just gets done.
I still get forty things before lunch. I'm still, at heart, a disorganized person. What's different is that I open my inbox now without the old flicker of dread, and most days I actually close it finished. Not because I became more disciplined, but because I finally built the thing that stopped asking me to be.
That's Campbooks. It started as a way to get receipts to my accountant on time. It turned into the inbox I'd always wanted and never once managed to keep. If you recognize any of yourself in this (the neglected inbox, the little graveyard of abandoned productivity apps, the low hum of guilt underneath both), then I didn't only build it for me. Come try it.

]]>Campbooks is an email client. The part that's different: it reads what comes in, attachments included, and does the filing. Invoices, receipts, contracts and the rest get sorted and turned into searchable documents, and what's left is a shorter list of mail that actually wants a reply. That's most of the pitch.
It sorts your incoming mail and the documents attached to it, and it learns when you correct it. There's a quick review mode called Skim for clearing whatever's left. None of this is magic. It gets things wrong, you fix them, and it gets wrong less often.
Scout is the assistant. It summarizes what arrived, answers questions about your mail and documents, and writes draft replies. It does not send anything for you, and it does not do things quietly in the background. An assistant that "handled the rest" while you weren't looking seemed like a bad idea, so we didn't build that one.
The rest, briefly. Your documents are searchable and export to Google Drive or Notion. There's a calendar that syncs both ways with Google or Zoho. There are workflow automations and a REST API for wiring it into other things. It connects to Gmail, Zoho, and Microsoft 365, and it's translated into English, Portuguese, Spanish, and French.
It's a first release and it's beta. Parts of it are rough. The hosted version is invite-only for now, which is a polite way of saying we're not confident enough to open the doors yet.
If you'd rather not wait for an invite, or not hand your mail to a company you've never heard of, you can run the whole thing yourself. It's source-available under the Sustainable Use License, installs with Docker, and needs no AI keys at all until you add your own.
Next on the list: native apps, push notifications, plain IMAP for everything else, and more of the automations people keep asking for. It's source-available, so if something's missing you can file it or write it yourself.
