NewsletterOS

About NewsletterOS

NewsletterOS is an AI-native email newsletter platform for creators and small businesses. It pairs a rich-text campaign editor with a BullMQ-driven worker that generates subject lines, drafts full newsletters from a prompt, optimizes send times, and runs drip sequences. Real-time analytics, A/B subject-line testing, mobile and desktop preview, and Stripe billing round out the product. Postgres (forge-control) holds the data and Better Auth handles sign-in; MailStackOS or SendGrid powers delivery. i18n ships in English, Spanish, French, and German.
