Automated Space-Themed Birthday Emails with NASA Images, GPT-4, Gmail & Slack

Who's it for? This template is perfect for teams, communities, or anyone who wants a fun, automated way to remember and celebrate birthdays. If you love space and want to make someone's special day a little more cosmic, this is for you. It's a great way to boost morale and ensure no one's birthday is forgotten. How it works / What it does The workflow runs automatically every morning. It reads a list of birthdays from your Google Sheet and checks if any match the current date. If a match is found, it fetches the latest Earth image from NASA's EPIC API and uses an AI model to generate a unique, space-themed birthday greeting. Finally, it sends a personalized HTML email to the birthday person and posts a celebratory message in your designated Slack channel. Requirements A Google Sheet with columns for Name, Email, and Birthday (in a format like YYYY-MM-DD). Credentials for Google Sheets, Gmail, OpenAI, and Slack configured in your n8n instance. How to set up Configure Credentials: Add your API credentials for Google (for both Sheets and Gmail), OpenAI, and Slack in the respective nodes. Set Up Google Sheet: In the "Get Birthday Roster" node, enter your Google Sheet ID and the name of the sheet where the birthday list is stored.
