Using GitHub Actions and Python, this repo automatically scrapes the content of the BBC's homepage every four hours and sends the content to me as an attachment in my email if it has been changed. You'll want to update the repository secrets with a SENDGRID_API_KEY, TO_EMAIL and FROM_EMAIL.
A tiny combo of autoscraper-mailer and autoscraper-history, which are in turn a simple Python-driven example of @simonw's Git Scraping.
