peter.clark@gmail.com via Postmark.

@@ -16,6 +16,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - **`caldave-mcp` npm package** — standalone MCP server published as `caldave-mcp` on npm. Run with `npx caldave-mcp` with `CALDAVE_API_KEY` set.
 
 - **Postmark webhook event logging** — new endpoint ingests Postmark delivery, bounce, spam, open, and click events into a `postmark_webhooks` table for email deliverability debugging. GET the same URL to view recent events.
+- **Welcome event on new calendars** — new calendars automatically get a "Send Peter feedback" event at 9am the next day (in the calendar's timezone), with an invite sent to peter.clark@gmail.com.
 
 ### Fixed
 - **`trust proxy` for Fly.io** — set `app.set('trust proxy', 1)` so `express-rate-limit` correctly identifies clients behind Fly's reverse proxy. Fixes `ERR_ERL_UNEXPECTED_X_FORWARDED_FOR` validation errors on every cold start.
