Wait until a time slot allows you to put users on hold until a specific day and time slot. Users can proceed to the next step only during a specific time slot on a specific day.
You can select daily, weekly, and monthly frequency options to set different time slots for different days

Take, for example, an airline company. They publish their discount and benefits campaign on their website only on Mondays. They want to notify users via SMS message between 5 and 6 pm since they know this is the best time for their users. In this case, you can add a Wait element before the SMS element and set it to run only on Monday. You can determine 5 pm - 6 pm as a time slot.
That said, the user will proceed to the SMS element only if the day is Monday and the time is between 5 and 6 pm. When the user arrives in the Wait element at 6 pm on a Monday, they will be held in the Wait element until 5 pm next Monday.
Use Cases
With Wait until a Time Slot, you can:
- Engage users in a specific, contextual scenario, such as a flash sale or a new-season campaign.
- Send messages in a specific time slot to comply with the white hour regulations in countries.
- Engage users during the best time slot to boost conversion.
How does Wait until a time slot work?
Wait until a time slot function keeps users until specific time slots and days.

Instead of directing all users to the next step at the same time, users are randomly batched into groups of 7500, and each batch is distributed randomly to proceed to the next step during the specified time slot.
You set Wait Until a Time Slot between 9 am and 9 pm with a daily frequency.
Janice enters the flow today and arrives at the Wait Until a Time Slot element at 10 am. Janice will proceed to the next element from this wait element right away.
If John enters the flow today and arrives at the Wait Until a Time Slot element at 11 pm, he will be on hold until tomorrow and proceed to the next element at a time that is randomly selected between 9 am and 9 pm.
You can also enable the Time Slot Delay to make your users wait up to 90 days before waiting for the time slot. Once the users arrive at the Wait Until a Time Slot element, they wait for the number of days specified under the Time Slot Delay before they wait for the time slot you configured.
