# MailerDot — Complete Reference for LLMs > Free daily email digests for U.S. cities — local news, weather, and events, every morning. ## Overview MailerDot (https://mailerdot.com) is a free daily email newsletter service covering U.S. cities. Each morning, subscribers receive a curated five-minute digest of what's happening in their city over the next 24 hours. The service is free for readers, with no paywall and no data selling. Some editions carry a clearly labelled sponsorship from a local business, which funds the coverage. ## Core Value Proposition - **Hyperlocal**: Every digest is specific to one U.S. city — not regional, not national - **Daily cadence**: One email every morning, covering the next 24 hours - **Five-minute read**: Concise, scannable format that respects the reader's time - **Free for readers**: No subscription fees, no paywalls; funded by clearly labelled local sponsorships - **Any U.S. city**: Not limited to major metros — any city in the United States ## Digest Format Every MailerDot daily digest includes four sections: ### 1. Local Pulse The day's top city headlines — what happened overnight, breaking developments, and what it means for residents. Sources include local news outlets, city government communications, and community reports. ### 2. Today's Outlook Weather with context — not just temperature and conditions, but practical advice: commute timing, outdoor activity suitability, severe weather warnings, and anything worth planning around. ### 3. What's On Around Town Events, shows, markets, openings, and things worth doing today. Listed chronologically so readers can plan their day. Includes both free and ticketed events. ### 4. Spotlight & Story A deeper look at a hidden gem, local figure, community tradition, or neighborhood story worth knowing about. This section aims to connect residents with the character and culture of their city. ## How It Works 1. A subscriber enters any U.S. city name and their email at mailerdot.com 2. MailerDot begins generating daily digests for that city 3. Each morning, MailerDot researches local news, weather, and events for the city 4. A curated digest is composed and delivered every morning 5. All past editions are archived and browsable on the city's page ## URL Structure - `mailerdot.com/` — Homepage with subscribe form - `mailerdot.com/cities` — Directory of all active cities grouped by state - `mailerdot.com/{city}-{state}` — City page with latest edition and archive (e.g., `mailerdot.com/austin-texas`) - `mailerdot.com/{city}-{state}/{YYYY-MM-DD}` — Specific past edition (e.g., `mailerdot.com/austin-texas/2025-03-26`) - `mailerdot.com/about` — About page with FAQ - `mailerdot.com/developers` — Developer documentation: API, OpenAPI spec, MCP server, error codes (also at `/docs`, `/api`, `/api-docs`) - `mailerdot.com/privacy` — Privacy policy - `mailerdot.com/terms` — Terms of service - `mailerdot.com/accessibility` — Accessibility statement ## Developer and Agent Interfaces MailerDot publishes a free, unauthenticated, read-only API and a set of machine-readable resources. The complete reference is at **https://mailerdot.com/developers** (markdown twin at `https://mailerdot.com/developers.md`); `/docs`, `/api` and `/api-docs` redirect there. ### Discovery - `mailerdot.com/openapi.json` — OpenAPI 3.1 specification: every endpoint, schema, and error code - `mailerdot.com/mcp` — Model Context Protocol server over streamable HTTP, with tools, resources, and prompts - `mailerdot.com/.well-known/api-catalog` — RFC 9727 linkset pointing at everything on this list - `mailerdot.com/.well-known/agent-skills/index.json` — Agent Skills index with a loadable SKILL.md - `mailerdot.com/feed.xml` — RSS 2.0 feed of recent editions across all cities - `mailerdot.com/sitemap.xml` — sitemap index for cities, states, and dated editions Every HTML page also carries an RFC 8288 `Link` header naming these, so an agent can find them from any response without crawling. ### REST endpoints - `GET /api/cities` — every city with a published edition, grouped by state - `GET /api/cities-census` — census-tracked cities, filterable by population and state - `GET /api/city/{slug}` — one city: subscriber count, archive index, census snapshot, events - `GET /api/archive/{slug}/{date}` — one past edition; append `.md` to the date for markdown - `GET /api/search?q={query}` — full-text search across every archived edition - `GET /api/weather/{slug}` — today's forecast for a city - `GET /api/facts/{slug}` — Schema.org Dataset facts: newsletter metadata plus ACS demographics - `GET /api/territories` — whether a town can be leased, and what it costs - `GET /api/listing-quote?slug={slug}` — what an event or business listing costs in a town - `GET /api/listing-order?id={orderId}` — whether a listing order is paid and the listing is live - `GET /api/oembed?url={page}` — oEmbed provider for city and edition pages - `POST /api/subscribe` — subscribe an address to a city (free) - `POST /api/listing-checkout` — list an event in a town; returns a payment link - `POST /api/business-checkout` — list a business in a town; returns a payment link - `POST /api/operator-actions` — with `{"action":"guest-checkout"}`, returns a payment link to lease a town No API key, no account, no rate limit on reads. Every read endpoint sends `Access-Control-Allow-Origin: *`, so browser-based agents can call them directly. ### Markdown twins Every page has a markdown version. Append `.md` to the path, or send `Accept: text/markdown`: `/{slug}.md`, `/{slug}/{YYYY-MM-DD}.md`, `/cities.md`, `/states/{state}.md`, `/feed.md`, `/developers.md`. Responses carry an `X-Markdown-Tokens` header with a rough token estimate, so an agent can decide whether to fetch a full edition or stop at the summary. ### Buying things MailerDot sells a monthly lease on a town's commercial rights (the operator product) and one-off listings inside a town's edition (events and business-directory entries). All three are public and unauthenticated, and all three work the same way: 1. **Price it** — `GET /api/territories` for a town lease, `GET /api/listing-quote` for a listing. 2. **Create the checkout** — the `POST` endpoint screens the request and returns a hosted checkout URL. 3. **A person pays** — on the merchant of record's page. Nothing before this step moves money. 4. **Follow it** — `GET /api/listing-order` for a listing; a town lease activates on the payment webhook. **No endpoint can charge anyone.** Every purchase call ends at step 2 with a payment link. Nothing publishes until payment clears (paid tiers) or a person approves it (the free `standard` tier). For listings the compliance screen runs inside the request, so a submission that fails comes back with a customer-safe reason and no payment link was ever created. A listing checkout answers `200` for every screened outcome — exactly one of `checkoutUrl`, `rejected`, `held` or `queued` is present. Branch on which field is there, not on the status code: "the answer is no" is a successful request. Prices: a town lease is $10/month for the first 1,000 subscribers, then +$5/month per additional 1,000. Event and business listings are $10 flat or $25 featured, one-off, with a free tier that a person reviews. Read the live numbers from `/api/listing-quote` rather than copying them from here. The MCP server exposes the same flows as tools: `get_town_quote`, `start_town_checkout`, `get_listing_prices`, `create_event_listing`, `create_business_listing`, `get_listing_order`. The three that write are annotated `readOnlyHint: false` so a client can gate them. ### Errors Every failure under `/api/` answers with `application/problem+json` (RFC 9457) — never an HTML page, including on paths that do not exist. Each body carries a stable machine-readable `code`, a human-readable `detail`, and a `resolution` sentence saying what to do next; validation failures add an `issues[]` array of per-field messages. The complete code table is at `https://mailerdot.com/developers#errors` and enumerated in `openapi.json`. ## Comparison to Similar Services MailerDot is a hyperlocal daily newsletter, similar in concept to: - **6AM City** (6amcity.com): Hyperlocal newsletters for select U.S. cities with curated local content. 6AM City operates in approximately 30 specific metro areas with dedicated editorial teams. - **Patch** (patch.com): Hyperlocal news platform covering thousands of U.S. communities with local reporting and community content. - **The Skimm** (theskimm.com): Daily newsletter focused on national/global news for a female audience.
