Stop Handing Claude Your Entire Inbox — Bills Get Recorded Through a Dedicated Agent Email Instead (Patreon)

You can now forward a bill to a completely separate email address and have Claude read it, check it for duplicates, and log it straight into your sheet, without ever giving Claude the keys to your real Gmail or Outlook.

If you went through the original Claude Runs Inbox training, you know the setup worked, but it meant handing your agent full access to your actual inbox, every email, every attachment, everything, just so it could dig out the two or three that were bills. That always bugged me a little. It's a lot of trust to hand over for what's really a narrow job. I wanted a version where the agent only ever sees what I choose to send it, nothing more.

That's what this update gives you. I found a free service called AgentMail that exists specifically to give AI agents their own inbox, and I built the whole workflow around it. You sign up, no credit card needed, and you get three separate inboxes, three thousand emails a month, and three gigabytes of storage, completely free. I set one up called Randy's Bills, grabbed an API key, handed it to Claude, and told it two things: here's the key, record any bill sent to this address into my Google Sheet, and don't create duplicates. That's it. From there I just forward a bill and wait.

And it works the way you'd hope. I forwarded an invoice, Claude pulled the vendor, the amount, the date straight out of the PDF, checked the sheet for anything already matching it, wrote the new row in, and emailed me back a confirmation telling me exactly which row it landed in. No browser control needed for the read side of it, Claude connected straight through Google Drive to write into the sheet once I added that connector, which is a cleaner, faster path than the original version ever had.

I also went back into the Inbox Expense Capture skill and rebuilt it to walk you through this. It used to only set you up for Gmail, Outlook Classic, or the new Outlook. Now Agent Mail is in there as an option too, so the skill will interview you and configure whichever inbox type you're actually using.

Go grab the updated Inbox Expense Capture skill first, that's the fastest way in, then set up your free AgentMail inbox and connect it the way I walk through in the training. This is exactly the kind of thing your membership is built for, I use this stuff myself, and when I find something better, you get it too.

📥Your updated training and the revised skill download are both waiting for you below, go set up your agent inbox and forward it your next bill.
