Generate AI-Powered Weekly Email Newsletters from WordPress with Gemini

This n8n workflow automates the creation and distribution of weekly email newsletters, leveraging the power of AI to generate engaging content from your WordPress posts. It simplifies the process of keeping your audience updated with your latest content, ensuring a consistent and personalized communication strategy.

What it does

This workflow performs the following key steps:

1. Triggers Weekly: The workflow is scheduled to run on a weekly basis, ensuring regular newsletter generation.
2. Fetches WordPress Posts: It connects to your WordPress site to retrieve recent posts.
3. Generates Newsletter Content with AI: Using the Google Gemini Chat Model via an AI Agent, it processes the WordPress post data to generate a compelling newsletter draft.
4. Conditional Email Sending: It includes an "If" node, allowing for conditional logic. This could be used, for example, to check if new posts exist or if the AI-generated content meets certain criteria before sending.
5. Sends Email Newsletter: If the conditions are met, the workflow sends out the AI-generated newsletter via email.
6. Code Execution (Optional/Helper): A "Code" node is present, which can be used for custom data manipulation, formatting, or additional logic within the workflow.
7. Sticky Note (Documentation): A "Sticky Note" is included for internal documentation or notes about the workflow.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• WordPress Account: Access to a WordPress site with posts.
• Google Gemini API Key: An API key for the Google Gemini Chat Model (configured within the "Google Gemini Chat Model" node).
• SMTP Credentials: Configuration for sending emails via an SMTP server (configured within the "Send Email" node).

Setup/Usage

1. Import the Workflow: Download the JSON provided and import it into your n8n instance.
2. Configure Credentials:
   • WordPress: Configure your WordPress credentials in the "Wordpress" node.
   • Google Gemini Chat Model: Provide your Google Gemini API key in the "Google Gemini Chat Model" node.
   • Send Email: Set up your SMTP credentials in the "Send Email" node.
3. Customize Nodes:
   • Schedule Trigger: Adjust the schedule in the "Schedule Trigger" node to your preferred frequency (e.g., specific day and time each week).
   • Wordpress: Configure the "Wordpress" node to fetch the desired number of recent posts or posts from a specific category.
   • AI Agent: Customize the prompt in the "AI Agent" node to guide Gemini on how to structure and summarize your newsletter content (e.g., "Create a weekly newsletter summarizing the latest blog posts. Include a catchy subject line and a call to action for each post.").
   • If: Modify the conditions in the "If" node if you have specific logic for when to send the newsletter (e.g., {{ $json.newPostsExist }} or {{ $json.aiContentApproved }}).
   • Send Email: Customize the recipient, sender, subject, and body of the email in the "Send Email" node, using expressions to dynamically insert content generated by the AI agent (e.g., {{ $('AI Agent').item.json.subject }} for the subject and {{ $('AI Agent').item.json.body }} for the email content).
   • Code: If needed, add custom JavaScript logic in the "Code" node to transform data or add specific functionalities.
