User's Guide

Welcome to NewsletterOS — the AI engine that turns the signal already sitting in your inbox into a polished, branded newsletter (plus a matching LinkedIn post) in minutes. This guide walks you through everything from first login to publishing and growing your audience.

1. Getting started

  1. Go to your NewsletterOS site and click Get started (or Sign in if you already have an account).
  2. Create your account. You'll land on your Dashboard.
  3. The first time in, a workspace is created for you automatically. Before your first edition, spend a few minutes in Settings (next section) to set up your brand and schedule.

2. One-time setup (Settings)

Open Settings from the top navigation. Each section saves independently.

Tip: Good sender/keyword lists are the difference between a noisy scan and a great one. Refine them after your first run.


3. Connect your email

You scan your own inbox, so connect it once:

  1. Go to CreateStep 1: Setup.
  2. Under Gmail accounts, click + Connect Gmail and approve access on Google's screen.
  3. The account is stored securely and reused — no need to reconnect each session.

Your plan sets how many accounts you can connect (Personal 1 · Pro 3 · Agency 10). To remove one, click the × next to it.

If you're ever asked to reconnect, just run + Connect Gmail again — your settings are unaffected.


4. Create a newsletter (the 4 steps)

Click Create (or Resume on the dashboard). You'll move through four steps.

Step 1 — Setup

Step 2 — Research

If a scan times out, narrow the date range or trim your senders/keywords in Settings, then scan again.

Step 3 — Interview

NewsletterOS asks your interview questions (the standard four — Theme, Highlights, Small-business angle, Enterprise angle — unless you've customized them in Settings → Interview questions) and drafts an AI-suggested answer for each from your scan.

Edit any answer freely, or click ↻ Regenerate on a single field to get a fresh AI take — your final answers are the editorial direction the AI follows when writing. When you're happy, click Generate newsletter →.

Step 4 — Generate

The AI writes your full newsletter and saves it. You're taken straight into the Editor.


5. Edit & brand your edition

The Editor has your content on the left and a live preview on the right. Everything autosaves — watch for the ✓ Saved indicator.

You can edit:

Other controls:

When ready, click ↓ Export email + LinkedIn to download both HTML files.


6. Re-open, edit again, or delete

Your editions are saved automatically — you never have to start over.


7. Publish

NewsletterOS produces the email and LinkedIn HTML; you send through your own tools:


8. Grow your audience (LinkedIn module)

Open LinkedIn from the navigation.

Sending always stays manual — NewsletterOS drafts and tracks, you send. That keeps you safely within LinkedIn's rules.
