Author here. A few technical notes if you’re interested in testing the CLI:

- Scheduling uses your local timezone and randomizes within workHours from config.json.

- Dry-run mode writes to CSV without sending, so you can inspect first.

- Requires a Resend API Key for live schedule.

- Suppressions list (bounces/unsubscribes) is stored locally in suppressions.json.

Built this over a weekend because I was frustrated. If you spot bugs or missing features, let me know and I'll fix them.
