Email newsletters have been a cornerstone of online communication for many years. Different from social media channels that depend on algorithms for visibility, email newsletters arrive directly in subscribers’ inboxes, providing more control over message delivery.

This tutorial will guide you in creating a newsletter generator using DigitalOcean’s 1-click models and integrating it with a Gradio interface. The objective is to show how system prompts can enhance your newsletter writing process, making it faster, more efficient, and authentic while maintaining high-quality content.

The tutorial is divided into three sections:

1. Setting up the 1-click model.
2. Customizing your prompts for the newsletter context.
3. Implementing the generator with Gradio.

Setting Up the 1-Click Model

DigitalOcean, in partnership with Hugging Face, provides 1-click models that enable developers to integrate GPU Droplets with powerful open-source language models through Text Generation Inference applications. Using open-source models allows for better data transparency and control during inference.

Prerequisites

While previous coding experience may be helpful, you can still create a newsletter generator without extensive knowledge of Python. Tools like Cursor are available to assist in code generation and modifications.

Part 1: Setting Up the 1-Click Model

1. Account Creation: Sign up for DigitalOcean if you don’t already have an account.

2. Accessing GPU Droplets: Go to the “Create GPU Droplet” page.

3. Choosing a Datacenter: Pick a datacenter region according to your preference.

4. Selecting the 1-Click Model: Under the “1-click Models” tab, choose the desired model.

5. Choosing a GPU Plan: Currently, you can select either 1 or 8 H100 GPUs.

6. Volumes and Backups: If required, you can select additional storage options or automated backups.

7. SSH Key: Add an existing SSH key or create a new one for secure access.

8. Advanced Options: Customize your GPU Droplet settings as needed.

9. Launching the Droplet: Complete the details and create your GPU Droplet. The deployment typically takes 10-15 minutes.

10. Web Console Access: Once deployed, access the web console to interact with your Droplet.

11. Using cURL or Python: Choose either cURL for quick testing or Python for a more controlled programming interaction.

Part 2: Newsletter Generation and Prompt Engineering

To create an engaging newsletter, it’s crucial to include meaningful content that appeals to readers’ interests beyond just product promotion. Following the 80/20 rule—where 80% of the content provides value and only 20% is promotional—can help maintain this balance. Successful newsletters emphasize engaging subject lines, clear formatting, mobile-friendly designs, and consistent delivery.

Proper system prompts are essential; they provide context and guidelines for what the outputs of your newsletter generator should resemble. The more descriptive and specific your prompts are, the better you can control the generated content.

Part 3: Gradio Implementation

For our implementation, we’ll utilize Gradio to create a web interface for our newsletter generator. Imagine a fictional streaming service, Lumina, which features AI-generated content. The marketing team at Lumina can provide specific requirements to tailor the newsletter content, aiming to excite readers about the platform.

1. Set Up a Virtual Environment: Use pip to create a virtual environment and install the necessary packages, including Gradio.

2. Import Statements: Set up your Python environment by importing necessary libraries.

3. Establishing Client Connection: Connect to the deployed model by specifying the GPU Droplet’s address and incorporating the Bearer Token.

4. Generate Newsletter Function: Create the function that takes parameters such as the headline topic and featured content to construct the newsletter.

5. Gradio Interface Creation: Set up the user interface using Gradio Blocks to facilitate easy input and output for newsletter generation.

6. Set Button Actions: Link buttons for generating newsletters and clearing inputs for user interaction.

7. Example Inputs: Provide sample inputs for users to test the functionality of the newsletter generator.

Conclusion

This tutorial has explained how to configure DigitalOcean’s 1-click models and illustrated the components of an effective newsletter. By utilizing a language model-powered generator, you can streamline and personalize the newsletter creation process, enhancing your marketing efforts.
