The last-run timestamp is stored in blob storage, so you never get the same item twice. If nothing new was published, no email is sent.\n\n## Setup\n\n1. Remix this val.\n2. In `main.tsx`, set `FEED_URL` to the feed you want (any RSS or Atom feed works).\n3. The cron is scheduled daily at 13:00 UTC (9am Eastern). Adjust the schedule on `main.tsx` in the editor if you want a different time — cron expressions run in UTC.\n4. Optional: click Run on `main.tsx` to test it immediately. On the first run it looks back 24 hours.\n\nThe digest is sent to your Val Town account email via `std/email`. No API keys or environment variables are needed.\n\n## Files\n\n- `main.tsx` — the cron handler: load `lastRunAt` from blob, fetch new items, send the digest, save the new timestamp\n- `rss.ts` — fetches and parses the feed (rss-parser), filters items newer than `since`\n- `digest.tsx` — renders the email HTML with Hono JSX\n- `email.ts` — `std/email` wrapper with a small retry, since sends can fail transiently\n",["D",1788149839316],"id","590ee86e-a49b-437f-bd36-3f58c91f7a89","steve-blank",["D",1788149839316],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","RSS feed
