Send using waves

Last update: April 11, 2025
  • Applies to:
  • Campaign v8 Web User Interface

To balance the load, you can divide email deliveries into several batches. Configure the number of batches and their proportion with respect to the entire delivery, as well as the interval between two waves.

NOTE
You can only define the size and the delay between two consecutive waves. The recipient selection criteria for each wave cannot be adjusted.

To send deliveries using waves, follow the steps below.

  1. Open the delivery settings.

  2. Browse to the Delivery section.

  3. Select the Send using multiple waves option.

  4. To configure waves, you can either:

  5. Prepare and send your delivery as usual. Learn more

    CAUTION
    Make sure the last waves do not exceed the delivery deadline, defined in the Validity tab, otherwise some messages might not be sent. A specific typology control rule, Wave scheduling check, ensures that the last wave is planned before the delivery validity limit. Learn more about control rules in the Campaign v8 (client console) documentation.
    You must also allow enough time for retries when configuring the last waves. Learn more

  6. To monitor your sends, go to the delivery logs. You can see the deliveries that were already sent in the processed waves (Sent status) and the deliveries to be sent in the remaining waves (Pending status).

Schedule multiple waves of the same size

If you select this option, all the waves have the same size (except the last one), and the delay between each wave is always the same.

Example of waves with the same size

  • Specify the size for all the waves you are splitting the delivery into. You can enter a percentage or a numerical value. Only the last wave can vary in size as it must include the remaining number of messages.

    For example, if you enter 30% in the Waves size field, the first three waves represent 30% of all the messages included in the delivery, and the fourth one stands for the remaining 10%.

  • In the Interval section, specify the delay between the start of two consecutive waves. For example, if you enter 2 days, the first wave starts immediately, the second wave will start in two days, the third wave in four days, and so on.

One common use case for using several waves of the same size is with a call center involved. When managing a telephone loyalty campaign, your organization has a limited capacity to process the number of calls to contact subscribers.

Using waves, you can restrict the number of messages to 20 per day, which is the daily processing capacity of a call center.

To do this, select the Schedule multiple waves of the same size option. Enter 20 as the waves size and 1 day in the Interval field.
