Automated Daily Market Email System

I need a turnkey workflow that grabs daily stock performance, major index movements, and the most relevant economic news headlines, then distills everything into a concise, high-level overview. The summary has to include clean charts or mini-graphs for quick scanning, and land in my inbox on a fixed schedule without fail.

Here’s what matters most to me:
• Data pulls come straight from dependable APIs so accuracy is never in doubt.
• The email arrives polished—well-formatted HTML is ideal, but I’m open to alternatives as long as readability on desktop and mobile stays intact.
• The entire pipeline (data fetch → summarisation → chart generation → email dispatch) runs automatically, can be monitored easily, and scales if I later add more tickers or extra sources.
• Code should be organized and documented well enough that routine tweaks—like changing the send time or swapping an API key—don’t require a deep dive.

Please bring experience with market-data APIs, automation frameworks such as Python + Cron/AWS Lambda/Zapier, email services (SMTP, SendGrid, SES, or similar), and a charting library that renders slick visuals on the fly. If you’ve built something similar, show me; it will speed up our kick-off conversation.
