The list

In no ranked order. The note beside each says what it is good for, which is a different thing from how big it is.

Each note describes the publication in its own terms. Briefwire reads what these sources publish, in public, and nothing else.

How the list was made, and what we do with it

Chosen by hand: Every source is here because people who work in E-commerce / DTC say substantive things on it, not because it is large. Enough of them to cover the field, few enough to audit.
Checked before listing: Each feed is fetched and checked when it is added and again whenever the library is re-checked by hand: one whose newest item is more than six months old fails, and one quiet for more than three is flagged but can stay listed. Every source is English-language and public.
Read, so you need not: You do not have to read all of them. Each new post is read, and the claims worth keeping are pulled out, each linked to the post it was written in.
When it is read: Briefwire reads a beat’s sources through the day while a trial or paid account tracks it. A beat nobody tracks may not be read at all, and its page shows the library, not a live feed.
Sent as a brief: The 12 lines that rank highest across the whole E-commerce / DTC beat go out daily or weekly. A claim several independent sources made ranks higher — that counts agreement, not accuracy.

The blogs and newsletters are one part of the beat. Every E-commerce / DTC source, all media — or just the podcasts or YouTube channels.
