Automate emails responses using ChatGPT, Dall-e 2 and Node-RED

Personalize emails and automatically respond based on email content, user data, and profile

What if you could create a chatbot-like tool, but for emails, using ChatGPT? Well, it’s possible, easy and, to be fair, cheap. It only requires you a few configurations for which you don’t need to be an expert to make 💪.

Dall-e 2 generated an image

I’ll show you how to create an email template and add a ChatGPT response to it. You might also want to use this to promote your product, but with custom, adapted text, for your customer profile, generated by the GPT.

I’m also going to implement Dall-e 2 image generation, as it could be useful to some of you and it’s quite fun.

Initial Node-RED setup

Let’s bring the Node-RED alive if you didn’t already by using the “Install NodeJS, NPM, and Node-RED on Raspberry Pi OS Lite 64-bit” then you can install it fast and easily by using Docker.

Install Node-RED using Docker and NgrOK tunnel

You don’t need the NgrOK or https:// for email sending or receiving, so you can skip these parts as we use an SMTP connection to the email account.

You can also deploy Node-RED on IBM Cloud, Horeku, Fly.io, or whatever is capable of hosting web apps, Docker containers, and Linux servers.

Create an email account with SMTP support

I expect that you already got an email address with the company domain for production, but for testing, if you can’t create another, then you can get a free Outlook or Gmail account.

For mass sending, I recommend you a service like SendGrid or Mailchimp.

Get SMTP enabled and details Outlook or Gmail, look at my article.

Good, after you get the SMTP / IMAP details for your email, it’s time to create a simple nodes flow.
