We're giving you more control over when messages are delivered! Now when you enable Quiet Hours for a campaign, you have the option of setting a fallback time zone for users whose timeZone field is empty or blank. Instead of defaulting to your project's time zone, you can tell Iterable to either apply the time zone of your choosing for users whose time zone is unknown, determine a user's time zone from the area code of their phoneNumber field, or skip the send for these users.
To learn more about this update and start using these new settings, see Quiet Hours.
