Update Email

Email service integration and notification system for the VaultoAI platform. Part of VaultoAI's internal tooling.

Overview

This Next.js application generates and sends daily market overview emails to configured recipients. It combines a TradingView market heatmap screenshot (via Puppeteer), prestock token performance data, and AI-generated market insights from Perplexity into a single HTML email sent through Resend. Scheduling is supported via Netlify cron or Vercel Cron. It is maintained by VaultoAI for internal and optional user-facing notifications.

Features

• Daily market overview email — Scheduled send (e.g. 10 AM UTC) with heatmap, token performance, and AI insights
• Preview and manual send — API routes to generate preview or send to custom recipients
• Resend integration — Reliable email delivery
• Perplexity integration — AI-generated market commentary
• Puppeteer — Screenshot capture for heatmap inclusion

Technology Stack

• Languages: TypeScript
• Frameworks / libraries: Next.js 14, React, Resend, Puppeteer, Netlify Functions
