Quiet hours

Avoid reaching out during inconvenient or inappropriate hours.

Last updated 12 days ago

Was this helpful?

Quiet hours are periods of the day when you should not send marketing messages. There are two good reasons for this:

  • Country-specific regulations: Many countries have regarding when you can send marketing messages via SMS. WhatsApp is unregulated, but we recommend that you set up your own custom WhatsApp quiet hours, and follow the SMS guidelines.

  • Marketing effectiveness: Marketing is much less effective during quiet hours. Since customers have a higher engagement rate during non-quiet hours, focus on sending messages during that period.

How quiet hours work

  • If a marketing message is sent, or scheduled to be sent, to a recipient with a phone number, we automatically check the quiet hours in the recipient's country.

  • If the message is scheduled to be sent during their quiet hours, the message will be queued.

  • The queued message will be sent immediately after the quiet hours end.

Example: Sending an SMS marketing campaign message to France

You schedule an SMS marketing campaign message to be sent to recipients in France. You schedule it to be sent on Thursday at 5:30 AM CET.

Since this is during France's quiet hours, the message will be queued. Quiet hours in France end at 8:00 AM CET. Your SMS marketing campaign message will be sent on Thursday at 8:00 AM CET.

Example: Sending a WhatsApp marketing campaign message to Brazil

You set up custom quiet hours for WhatsApp from 5:00 PM to 10:00 AM, in line with Brazil's SMS regulations. You schedule a WhatsApp marketing campaign message to be sent to recipients in Brazil. You schedule it to be sent on Thursday at 7:30 PM BRT.

Since this is during the quiet hours you configured for WhatsApp, the message will be queued. Your WhatsApp campaign message will be sent on Friday at 10:00 AM CET.

Supported platforms and activation

WhatsApp

Good to know

  • Quiet hours are optional for WhatsApp.

To activate quiet hours for WhatsApp, go to Preferences > WhatsApp > Activate custom quiet hours.

SMS

Please ensure the message validity period is set long enough to accommodate potential delays, especially if you expect messages to be sent during quiet hours

If a country has no quiet hour restrictions in place, your message will not be affected by any quiet hour restrictions.

You may choose to disable quiet hours enforcement for promotional messages using the Journey Send Message step or the Channel API by setting the ignoreQuietHours parameter to true. However, please ensure you fully understand the regulatory implications and potential risks. Disabling quiet hours may lead to non-compliance with local laws in certain countries

Regardless of your configuration, quiet hours are strictly enforced by local telecom networks in countries such as France and Uzbekistan. This means that messages sent during restricted hours will always be queued and delayed until the quiet period ends — even if ignoreQuietHours is set to true.

Quiet hours and Bird products

To determine if a message should be subject to quiet hours, we examine ongoing interactions and assess if the content is marketing-related. The following sections describe what we check for each Bird product.

Journeys and Campaigns

Quiet hours are not applied to campaign test messages.

  • WhatsApp: When you customer manually activate quiet hours, all messages using pre-approved WhatsApp marketing templates will adhere to these quiet hours.

Flows, API messages and Inbox

  • WhatsApp: When you manually activate quiet hours, and there is no ongoing conversation with the end-user, all messages using pre-approved WhatsApp marketing templates will be subject to quiet hours.

Channels API

  • WhatsApp: When you manually activate quiet hours, and there is no ongoing conversation with the end-user, all messages using pre-approved WhatsApp marketing templates will be subject to quiet hours.

Countries with multiple time zones

For countries with multiple time zones, we offer the option to use area codes to send messages to users according to their local time.

To activate the usage of area codes, go to Preferences > WhatsApp (or SMS) > Activate Area Codes.

We provide area codes for the countries listed in the table below, allowing campaigns to be sent at specific local times. Some regions in the US and Canada have multiple time zones within a single area code.

We also indicate the default time zone used when area codes are disabled and the scheduling times for messages sent during quiet hours. When required, we extend the quiet hours over multiple time zone to ensure all receiver, regardless of their location, are covered. These are also marked in the following table.
