The letter

The week’s strongest items that already shipped on @progressproof, by email. Same claims. Same sources. This list is the cash register — not a second feed.

We host the list. We don’t sell addresses. Unsubscribe once mail is live. Sponsors, when we take them, sit next to the letter and say so.

This week’s public letter is already up: read it here. The email is that page, sent.

Questions? Reach us on X at @progressproof.

How this pays for the desk

The letter is what we can sell without selling the truth gate: a disclosed sponsor mention, and a list of people who asked to be here. Tips and briefings live on Support. Brands: newsletter spots only.
