Curated inbox list

Frequently asked questions
- Which OSINT newsletters should I subscribe to first?
- Start with one methods letter (Sector035 or similar), one investigation outlet (Bellingcat), and one community source. Add more only when you actually open them.
- Does OSINTverse own or get paid to list these newsletters?
- No. This is a curated directory for learners. We include our Hub at the end so it is obvious what is ours versus the rest of the field. No paid placements.
- How often is this OSINT newsletter list updated?
- When a letter stops publishing, changes URL, or the community points us at something better. Suggest additions via [email protected].
