    What This Workflow Does

    This workflow watches specific YouTube channels for new videos. It finds videos made in the last 3 days and gets extra details from YouTube’s API. It sends emails and Telegram messages to notify about these new videos. This saves time and stops users from missing important updates. The system creates RSS feed URLs from a list of channel IDs, reads video feeds, filters recent posts, and enriches data with API calls. Then it builds nice HTML emails and Telegram posts with thumbnails and links.

    The Advanced Part: AI Summarizes and Distributes For You

    Most YouTube RSS workflows just send you a link. This one goes further.

    Once new videos are detected, OpenAI GPT-4o-mini reads the video
    metadata — titles, descriptions, thumbnails — and generates a
    professionally formatted HTML email digest automatically. No
    manual writing. No copy-paste.

    Then it distributes across two channels simultaneously:

    →

    Gmail

    — A polished HTML email with thumbnails and video links
    lands in your team's inbox, ready to read or forward.

    →

    Telegram

    — A clean message with thumbnail previews and clickable
    links goes straight to your chat group for instant awareness.

    This is what separates it from a basic RSS alert. Instead of raw
    feed data, your team gets a curated, AI-written update — formatted,
    branded, and delivered automatically the moment a new video goes live.

    Basic YouTube RSS vs This Advanced Workflow — What's the Difference?

    If you've seen basic YouTube RSS automations before, here's exactly
    what this workflow adds on top:

    | Feature | Basic RSS Workflow | This Advanced Workflow |
    | Detects new videos | ✓ | ✓ |
    | Filters by recency | ✗ | ✓ (last 3 days) |
    | Enriches with YouTube API | ✗ | ✓ (thumbnails, metadata) |
    | AI-generated email content | ✗ | ✓ (GPT-4o-mini) |
    | HTML formatted emails | ✗ | ✓ |
    | Telegram notifications | ✗ | ✓ |
    | Supports multiple channels | ✗ | ✓ (batch via channel ID list) |

    The basic version tells you a video exists.
    This version tells you what it is, shows you a preview, and
    delivers it formatted — across email and Telegram — without
    you touching anything.

    Use this if you're monitoring multiple channels, need team-ready
    digests, or want AI to handle the formatting work for you.

    Beginner Step-by-Step: How to Use This Workflow in n8n

    1. Download and Import the Workflow

    1. Click the Download button on this page to get the workflow file.
    2. Inside the n8n editor, click “Import from File” and upload the downloaded workflow.

    2. Configure Required Credentials and Settings

    1. Set up Google API Key with YouTube Data API enabled.
    2. Add Gmail SMTP credentials to the Multiple Emails and Single Email nodes.
    3. Enter Telegram Bot Token and Chat ID into the Telegram node.
    4. Input OpenAI API Key in the designated nodes for generating email templates.
    5. Update YouTube channel IDs in the YouTube Channel Ids node or prepare to submit via the form.

    3. Test the Workflow

    1. Run the workflow manually or submit channel IDs through the form trigger.
    2. Check if videos are fetched, emails are created, and messages are sent.

    4. Activate for Production

    1. Enable the schedule trigger node if daily automation is desired.
    2. Monitor workflow runs in n8n for any errors or issues.
    3. Adjust inputs or API keys as needed.
    For users managing their own server, consider self-host n8n for full control.

    Edge Cases and Common Failures

    • If a video ID is empty, the Label New Videos code may parse IDs incorrectly. Verify splitting logic for video ID extraction.
    • Gmail email failures often come from expired or incorrect OAuth2 credentials. Re-authentication fixes this.
    • Telegram notifications fail if bot token or chat ID is wrong. Confirm environment variables and bot chat membership.
    • Empty or invalid YouTube channel ID lists cause no RSS feeds to generate. Double-check input formats.

    Customization Ideas

    • Add Slack or other messaging channels by inserting corresponding nodes and changing payloads.
    • Change the "days" value in the Label New Videos code node to widen or narrow the new video window.
    • Extend video data fields to include view counts or comments from YouTube API for richer email content.
    • Modify the form trigger to mark dynamic recipients or input validation.
    • Tweak OpenAI prompt templates in the LangChain nodes to match brand colors or layouts.
