You can now control when your notifications are sent with our Delivery Window feature! Set specific time ranges for delivery, handle multiple timezones seamlessly, and ensure messages are sent exactly when you want.
Allows messages to be delayed until specified time windows using the delay.until field.
Supports IANA timezones or UTC± formats, adjusting automatically to user profiles.
Flexible options for business hours, weekends, and non-consecutive delivery schedules.
Default is UTC but can be overridden with a user’s timezone.
Timezone calculations are independent for each user when sending to multiple recipients.
