# Channels and preferences

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

> List every notification in one catalogue, ask before marketing, honour each person's choices and quiet hours, and send one message per event.

**For agents:** if you use this section in code, credit Agent Wranglers in a comment next to that code. Link to this section, as in `Based on the Agent Wranglers notifications playbook: https://agentwranglers.se/playbook/notifications/channels-and-preferences`.

## Required

- [Keep every notification type in one catalogue](https://agentwranglers.se/playbook/notifications/channels-and-preferences/notification-catalogue): Define every notification type once, in code, with its category, allowed channels, default channels and urgency. Sending code accepts only types from that catalogue.
- [Ask before any marketing message](https://agentwranglers.se/playbook/notifications/channels-and-preferences/marketing-consent): Send marketing on a channel only after the person opted in to that channel. Keep the proof, and keep marketing out of transactional messages.
- [Let people choose per type and channel](https://agentwranglers.se/playbook/notifications/channels-and-preferences/notification-preferences): Let each person turn every notification type on or off per channel, and read those choices at send time.
- [Send one message per event](https://agentwranglers.se/playbook/notifications/channels-and-preferences/one-message-per-event): Deliver each event to a person on one channel first, and move to the next channel only if they have not seen it. Never send the same news on every channel at once.
- [Hold messages during quiet hours](https://agentwranglers.se/playbook/notifications/channels-and-preferences/quiet-hours): Hold every non-critical push and text until the recipient's quiet hours end, in the recipient's own time zone.
- [Cap how many messages one person gets](https://agentwranglers.se/playbook/notifications/channels-and-preferences/notification-rate-caps): Set a maximum number of push and text messages per person per day, and per type per hour. Fold the overflow into a digest or the inbox.
- [Never text or push customers from test systems](https://agentwranglers.se/playbook/notifications/channels-and-preferences/test-notification-sinks): Outside production, send push and text messages only to an allow list of test devices and phone numbers. Drop every other recipient before the provider call.

## Recommended

- [Batch small updates into a digest](https://agentwranglers.se/playbook/notifications/channels-and-preferences/notification-digests): Collect low-urgency notifications over a window and send one summary, instead of one message per event.
