AI RSS Newsletter Bot for Bluesky, Telegram, Discord & Slack (n8n)

Turn your newsletter RSS into instant, AI-written social announcements (no manual posting)

This AI RSS Newsletter Bot for Bluesky, Telegram, Discord & Slack (n8n) monitors your newsletter’s public RSS feed and, when a new issue publishes, it uses AI to generate platform-native announcements and posts them automatically to Bluesky, Telegram and Discord—plus ready-to-paste X and LinkedIn drafts for Slack.

What this workflow does

• Detect new issues via RSS hourly: The “When a New Issue Is Published” step checks your newsletter archive RSS URL and triggers when a new issue appears. It works with any RSS-backed newsletter (e.g., Kit/ConvertKit, beehiiv, Substack, Ghost, Buttondown, etc.).
• Generate platform-native copy with AI: The bot builds a prompt from the issue details and uses Write Announcements With AI to create different outputs per channel (short and punchy for Bluesky’s 300 characters; more context for Telegram and Discord).
• Force strict formatting and safe publishing: It parses AI output as strict JSON (malformed responses fail loudly) and applies per-platform length limits in code before splitting into one post per channel.
• Post automatically + deliver drafts where needed: Announcements publish to Bluesky, Telegram, and Discord. X/Twitter and LinkedIn are provided as copy-paste-ready drafts in Slack (APIs are paid or review-gated).
• Keep only what you use: Delete channels you don’t need.

Use cases

• Newsletter operators who want consistent promotion across social platforms as soon as each issue goes live.
• SaaS teams running campaign workflows from newsletter RSS—without relying on ESP-specific integrations.
• Automation engineers who want a robust, JSON-validated AI content pipeline in n8n.
