Homepage with user Login + Email Automation

I’m building a single, responsive homepage from scratch in pure HTML, CSS and JavaScript. The page needs a custom-designed look and a straightforward email-and-password sign-up / log-in flow.

Every new or returning user’s email should be captured instantly and written to a connected Google Sheet (using Google Sheets API or an Apps Script—whichever you find cleaner). Once the address lands in the sheet, an n8n workflow must trigger and handle the automated emails I’ll supply.

To make hand-off easy, please deliver:
• Fully commented front-end code (HTML, SCSS/CSS, JS)
• Google Sheet integration script configured and tested
• n8n workflow file or JSON export with clear environment variables for SMTP/API keys
• A brief README covering setup, env variables and how to extend the flow

If you’ve previously paired custom front ends with Google Sheets and n8n, you’ll know exactly what to do. I value clean, reliable code and prompt communication, and I’ll be available to test each milestone as soon as it’s ready.
