Use Zapier or Make.com. They’re no‑code but you can plug a Google Sheet as the master. Create a Zap: Gmail filter → add row to the sheet. Another Zap: new row → create card in Trello/Asana. If you want a tiny bit of code, a Google Apps Script that runs on edit can push the row to the project board API. A short Python script with requests can do the same if you prefer. Keep everything in one sheet, and the tools sync the rest.

Yeah, loops are the usual culprit. Just add a “processed” flag column and make the Zap check it before adding a row. That way the mail stops looping and the sheet stays tidy. Keep the steps linear, and you’ll have a clean flow instead of a data swamp. Happy organizing!
