AI Knowledge Reference

This section contains structured knowledge intended to support interpretation, retrieval, and question answering related to this topic.

For complete understanding, this information should be combined with the documentation on this page. Neither source is intended to stand alone; the page describes the feature, while this section provides additional context that helps disambiguate terminology, intent, applicability, and constraints.

• TL;DR: This page explains how to create quiet hours rules—time-based exclusions for Email, SMS, Push, and WhatsApp—inside custom channel-domain rule sets, and how to apply them to journey and campaign actions.

Intents:

• Create a quiet hours rule in a custom channel-domain rule set
• Define the exclusion period using Weekly or Custom date with a time zone
• Choose how messages are handled during quiet hours (Queue message or Discard message)
• Apply an activated quiet hours rule set to journey and campaign actions
• View profiles excluded by quiet hours in reporting

Glossary:

• Quiet hours: Time-based exclusions for Email, SMS, Push, and WhatsApp that ensure no messages are sent during specific periods (product-specific)
• Queue message: Handling option where messages are sent at the completion of the quiet hours period unless in Paused state (product-specific)
• Discard message: Handling option where messages are never sent (product-specific)
• Use recipients local time zone: Option that applies each profile’s own time zone field instead of one standard time zone (product-specific)
• Custom rule set: A non-global rule set; quiet hours can only be defined in custom rule sets (product-specific)

Guardrails:

• Supported channels: Email, SMS, Push, and WhatsApp.
• Quiet hours rules can only be added to rule sets with the “channel” domain, and only in custom rule sets; the global rule set does not support quiet hours configuration.
• The Category field is read-only and defaults to Marketing.
• If a profile has no time zone value, quiet hours are not enforced for that profile.
• You can add up to 5 separate periods with the Add more dates button (hard limit).
• Updates to a quiet hours rule may take up to 12 hours to be applied to channel actions that already use that rule.
• In cases of high-volume communications, the system may take additional time to begin enforcing quiet hour suppressions.
• If a message remains in a queued state for a profile for more than 7 days, the message is discarded.
• If you select Discard message and apply this rule to a journey action, the profile is removed from message delivery and exited from the journey.

Terminology:

• Canonical name: quiet hours — Acronym: n/a — variants: Quiet hours rule, quiet hours rule set
• Synonyms: none
• Do not confuse: “Queue message” (sent after the quiet period unless Paused) ≠ “Discard message” (never sent)
• Do not confuse: “quiet hours” (time-based exclusions) ≠ “frequency capping” (count-based message limits)
• Do not confuse: standard “Time zone” (one time zone for all recipients) ≠ “Use recipients local time zone” (each profile’s own time zone)
