Hero \"Stay in touch\" button opens a modal that POSTs to `/api/subscribe`. |\n| `/admin` | Private campaign composer. Enter your admin token, write a subject + message, and send to all subscribers. |\n| `POST /api/subscribe` | Validates and saves `{ name, email }` to the `subscribers` SQLite table. |\n| `POST /api/send-campaign` | Admin-only (requires `ADMIN_TOKEN`). Emails every subscriber via Resend. |\n| `/source` | Redirects to the val's source code. |\n\n## Files\n\n| File | Role |\n| --- | --- |\n| `main.tsx` | HTTP server + API routes. |\n| `index.html` / `style.css` / `script.js` | The public site and subscribe modal. |\n| `admin.html` / `admin.js` | The private campaign page. |\n| `db.ts` | SQLite schema + `addSubscriber()`. |\n| `marketing.ts` | `sendCampaign()` — fans out emails through the Resend API. |\n\n## Setup for sending email\n\nVal Town's built-in `std/email` can only email **you**, so this uses\n[Resend](https://resend.com) (free tier: 100/day, 3,000/month) to reach real\nsubscribers. Three environment variables:\n\n1. **`RESEND_API_KEY`** — create a key at .\n2. **`ADMIN_TOKEN`** — any long random string. It protects `/api/send-campaign`\n so only you can trigger a send. You'll type it into the `/admin` page.\n3. **`FROM_EMAIL`** *(optional)* — e.g. `James `. Requires a\n domain verified in Resend. Until then it defaults to `onboarding@resend.dev`,\n which only delivers to your own Resend account email (fine for testing).\n\nSet them in the val's **Environment Variables** tab.\n\n## Personalization\n\nIn the campaign subject or body, `{{name}}` is replaced with each subscriber's\nname (falls back to \"there\" if empty).\n\n## Viewing subscribers\n\nThey live in this val's SQLite `subscribers` table (`id`, `name`, `email`,\n`created_at`) — browse it in the val's **Database** tab.\n\n## Structure\n\n```mermaid\nflowchart TD\n Visitor -->|Stay in touch| Modal --> subscribe[POST /api/subscribe] --> DB[(subscribers)]\n You -->|/admin + token| Compose --> campaign[POST /api/send-campaign]\n campaign --> DB\n campaign --> Resend[Resend API] --> Inbox[Subscriber inboxes]\n```\n",[214],"pulls","branches","forks","envVars",{"_226":43,"_228":43},"connections",{"_226":43,"_227":43},"count","unfilledCount","emptyCount",{"_18":213,"_20":214,"_137":215,"_139":-5,"_140":72,"_141":70,"_143":39,"_22":267,"_69":157,"_146":103,"_147":217,"_149":26,"_150":-5,"_240":268,"_93":269},{"_18":206,"_20":207,"_137":208,"_139":-5,"_140":72,"_141":209,"_143":39,"_22":264,"_69":43,"_146":103,"_147":211,"_149":26,"_150":-5,"_240":265,"_93":266},{"_18":199,"_20":200,"_137":201,"_139":-5,"_140":72,"_141":202,"_143":39,"_22":261,"_69":43,"_146":158,"_147":204,"_149":26,"_150":-5,"_240":262,"_93":263},{"_18":192,"_20":193,"_137":194,"_139":-5,"_140":72,"_141":195,"_143":39,"_22":258,"_69":43,"_146":158,"_147":197,"_149":26,"_150":-5,"_240":259,"_93":260},{"_18":185,"_20":186,"_137":187,"_139":-5,"_140":72,"_141":188,"_143":39,"_22":255,"_69":43,"_146":103,"_147":190,"_149":26,"_150":-5,"_240":256,"_93":257},{"_18":177,"_20":178,"_137":179,"_139":-5,"_140":72,"_141":180,"_143":39,"_22":252,"_69":182,"_146":103,"_147":183,"_149":26,"_150":-5,"_240":253,"_93":254},{"_18":168,"_20":169,"_137":37,"_139":-5,"_140":72,"_141":170,"_143":39,"_22":249,"_69":172,"_146":173,"_147":174,"_149":26,"_150":175,"_240":250,"_93":251},{"_18":161,"_20":162,"_137":163,"_139":-5,"_140":72,"_141":164,"_143":39,"_22":246,"_69":43,"_146":158,"_147":166,"_149":26,"_150":-5,"_240":247,"_93":248},{"_18":152,"_20":153,"_137":154,"_139":-5,"_140":72,"_141":155,"_143":39,"_22":243,"_69":157,"_146":158,"_147":159,"_149":26,"_150":-5,"_240":244,"_93":245},{"_18":135,"_20":136,"_137":138,"_139":-5,"_140":72,"_141":142,"_143":39,"_22":239,"_69":145,"_146":103,"_147":148,"_149":26,"_150":-5,"_240":241,"_93":242},["D",1781824399649],"children",[],[136],["D",1781824153743],[],[153],["D",1781824355518],[],[162],["D",1781824374010],[],[169],["D",1781824131508],[],[178],["D",1781823189606],[],[186],["D",1781824109125],[],[193],["D",1781824392802],[],[200],["D",1781824384097],[],[207],["D",1781824422909],[],[214],["D",1781823189606],["D",1789677107549],{"_16":17,"_91":86},{"_16":17,"_85":86,"_87":86,"_34":35,"_88":89,"_90":26},{"_69":70,"_20":71,"_18":72,"_73":19,"_74":75,"_76":77,"_78":28,"_79":80,"_81":82,"_83":21,"_84":17},"ctx",{"_62":-5,"_113":308,"_309":310,"_311":312,"_313":26,"_314":26,"_315":26,"_316":39,"_317":-5,"_318":-7,"_319":-7,"_320":43,"_321":26,"_322":26,"_323":-5,"_324":26,"_325":26,"_326":26,"_327":-5},"ENV",{"_279":280,"_281":282,"_283":71,"_284":285,"_286":287,"_288":289,"_290":291,"_292":293,"_294":295,"_296":297,"_298":299,"_300":301,"_302":303,"_304":305,"_306":307},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","71c1b20804b3232a7e513be260cfffc1932a9e97","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
