Quiet hours

How Landing Zone's quiet hours pause SMS and calls overnight in each contact's local time, and why they are a floor, not proof of lawful timing.

Quiet hours block outreach during the hours when people do not want to be contacted — overnight, by default. Landing Zone enforces them for SMS and calls, timed to each contact's local clock.

How quiet hours work in Landing Zone

By default, quiet hours run from 9 PM to 8 AM in the contact's local time. The window is evaluated per contact: a contact in one time zone can be inside quiet hours while a contact in another is not, even within the same batch.

Quiet hours are configurable per workspace — you can set the start time, end time, and timezone handling for your workspace. They are enforced for SMS and calls: the eligibility checks that run before batch and campaign SMS exclude contacts currently inside quiet hours, and outbound calling is gated the same way.

The contact's clock, not yours

The default window follows the contact's local time, not your own. If you are sending from the East Coast at 10 AM, a contact on the West Coast is still inside the default window until 8 AM their time. This is the behavior you want: what matters to the person receiving the message is their own morning, not yours.

What quiet hours do not do

Quiet hours are a floor, not proof of lawful timing. Sending inside the allowed window does not make a message or call lawful — consent, audience, and content requirements still apply regardless of the hour.

Timing rules also vary. State-specific rules can be stricter than the default window — narrower hours, or additional restrictions on certain days — and telephone consumer-protection rules apply on top of anything the app enforces. See State variation.

Your responsibilities

  • Know the timing rules that apply where your contacts are, and tighten your workspace quiet hours where those rules are stricter than the default.
  • Treat quiet hours as one control among several — pair them with recorded consent (Consent and contact permissions), opt-out handling (Opt-outs and STOP keywords), and repeat-contact limits (Repeat-contact cooldowns).
  • Remember that a permitted hour is not permission. The window controls when a message can go out, not whether it should.
