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","# steve-blank\n\nA bounded feed for [Steve Blank's writing](https://steveblank.com/).\n\n[Open the feed](url:main.tsx)\n\nThe archive has more than 700 posts, so this feed does not mirror it. It combines the 20 newest posts with all 34 posts in Steve Blank's own Customer Development Manifesto category, then removes duplicate URLs.\n\n`refresh.ts` updates the cache daily. `main.tsx` also refreshes a cache older than six hours and serves the last good copy if WordPress is temporarily unavailable.\n","createdAt",["D",1788150331699],"branchVersion","branchId","a5b4b800-cfe5-451b-9f5a-92c90e520f6e","id","590ee86e-a49b-437f-bd36-3f58c91f7a89","steve-blank",["D",1788149839316],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","RSS feed for selected Steve Blank essays","imageUrl","41fc127f-5d67-4e9d-aaf5-7f1531438361","pinnedFileId","01a05609-3692-749e-ab73-a579e513aaed","pinPreview",true,"pinMigrated","screenshotVersion","likeCount",0,"orgId","9dd2e27d-d103-40dd-bb45-da8e837d341a","tursoName","tursoHostname","tursoMeasuredAt","pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_96":95,"_103":99},"org",{"_96":95,"_97":-5,"_98":99,"_18":54,"_100":101,"_102":25},"branch",{"_13":85,"_32":86,"_42":41,"_87":43,"_88":-5,"_89":-5,"_90":-5,"_91":-5,"_92":-5,"_93":44,"_94":95},"isOwned",11,"main","projectId","forkedBranchId","forkedBranchVersion","forkedProjectPrivacy","forkedProjectId","forkedProjectOrgId","projectName","userHandle","ivryb","handle","displayName","avatar","https://img.clerk.com/eyJ0eXBlIjoicHJveHkiLCJzcmMiOiJodHRwczovL2ltYWdlcy5jbGVyay5kZXYvb2F1dGhfZ2l0aHViL2ltZ18yZkFtS1dWcU5NYWRjQkN5MGVCUTVRS0Z5SkEifQ","tier","free","canRestrictVals","profileImageUrl","branchName","","adoptOrgId",{"_42":43,"_32":44,"_37":194,"_46":-5,"_47":25,"_48":49,"_50":49,"_51":52,"_53":-5,"_18":54,"_55":56,"_57":58,"_59":-5,"_60":-5,"_61":62,"_63":64,"_65":-5,"_66":-5,"_67":-5,"_68":-5,"_69":70,"_71":70,"_72":73,"_74":73,"_75":73,"_76":70,"_77":70,"_78":195,"_80":196,"_82":197,"_84":25},"tree",[173,174,175,176,177],"files",[173,174,175,176,177],"counts",{"_163":62,"_164":135,"_165":62,"_166":167,"_168":169},"contents",[126,127,128,129,130],"upstreamProject","upstreamBranch","emptyEnvVars","flags",[],"hasHttpFiles","grants","orgs","customDomains",{},{"_42":160,"_32":28,"_30":31,"_134":-5,"_40":41,"_39":14,"_136":25,"_37":161,"_13":135,"_33":20,"_34":36,"_24":25,"_140":-5,"_27":162},{"_42":154,"_32":155,"_30":156,"_134":-5,"_40":41,"_39":135,"_136":25,"_37":157,"_13":62,"_33":138,"_34":158,"_24":25,"_140":-5,"_27":159},{"_42":148,"_32":149,"_30":150,"_134":-5,"_40":41,"_39":135,"_136":25,"_37":151,"_13":62,"_33":138,"_34":152,"_24":25,"_140":-5,"_27":153},{"_42":142,"_32":143,"_30":56,"_134":-5,"_40":41,"_39":135,"_136":25,"_37":144,"_13":62,"_33":145,"_34":146,"_24":25,"_140":44,"_27":147},{"_42":131,"_32":132,"_30":133,"_134":-5,"_40":41,"_39":135,"_136":25,"_37":137,"_13":62,"_33":138,"_34":139,"_24":25,"_140":-5,"_27":141},"d1fe93f6-e4fa-4c06-8b9f-42581545349b","rss.ts","01a05609-3692-749e-ab73-a93c5242867f","parentId",1,"latest",["D",1788149839316],"script","import Parser from \"npm:rss-parser@3.13.0\";\n\nexport interface FeedItem {\n title: string;\n link: string;\n date?: Date;\n snippet?: string;\n}\n\n// Fetch the feed and return items published after `since`, newest first.\nexport async function fetchNewItems(url: string, since: Date) {\n const res = await fetch(url);\n if (!res.ok) throw new Error(`Feed fetch failed: ${res.status} ${url}`);\n const feed = await new Parser().parseString(await res.text());\n\n const items: FeedItem[] = (feed.items ??
