Each card answers three things in plain English:
We also publish a longer Wednesday brief. The product is in Preview (early access).

There is no large newsroom. One editor selects and summarizes public seller updates. We do not invent deadlines, fees or quotes. If a number is unclear, we say so or wait for a primary source.
We include an item when it is publicly announced by a marketplace or a primary corporate / Seller Central / Seller University / changelog source, or a high-signal secondary report that points back to a primary source we can link.
We prefer policy and fee changes with dates, fulfillment and returns rules, new seller tools, and agentic commerce changes that affect discovery or checkout. We skip pure opinion, rumors without a named primary source, and duplicate coverage of the same change.
Every card keeps a labeled link to the original source. Daily Heads Up is a heads-up layer, not a replacement for Seller Central or Seller University.
