The event matrix

The matrix on the Notifications page crosses every event type with every channel. These are the events and their out-of-the-box defaults:

The pattern: the four safety events (kill-switch, reconciliation drift, risk caps, billing) default fully on, and so does the in-app and email side of the broker-connection alert, sent once when Alpaca stops accepting your saved keys (see Keys that stopped working); informational events default to the in-app inbox; the digest is fully opt-in (see Digest emails). Every in-app and email cell is yours to flip, with a few exceptions: the kill-switch email always sends — a confirmation of a Pause, Cancel, or Liquidate is a safety alert that can’t be turned off, so its email cell stays pinned on (each kill-switch action is also recorded in your audit log, independent of any notification setting) — two informational notices, the backtest result and the “Universe updated” summary, appear only in the in-app inbox, so their email and push cells stay off — and the broker-connection and “Universe list rules updated” alerts send no push, so their push cells stay off. The push column is interactive only when push support is switched on for SleeveFolio; until then it shows “soon” and email plus the in-app inbox carry everything. Once push is available, an “Enable push on this browser” button appears in Notifications settings so you can grant your browser’s permission on each device.
