Send using waves
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.
NOTETo send deliveries using waves, follow the steps below.
-
Open the delivery settings.
-
Browse to the Delivery section.
-
Select the Send using multiple waves option.
-
To configure waves, you can either:
-
Prepare and send your delivery as usual. Learn more
CAUTIONMake 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 -
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.
-
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.
Schedule waves according to a calendar
If you select this option, define the start day/time for each wave you are sending, as well as the size of each wave.
-
In the Start fields, specify the delay between the start of two consecutive waves.
-
In the Size column, enter a fixed number or a percentage.
Add as many waves as needed. Reorder them according to your requirements.
NOTEIn the example below, the first wave represents 25% of the total number of messages included in the delivery and starts immediately. The next two waves complete the delivery and are set to begin at six-hour intervals.
One common use case for using multiple waves according to a calendar is during the ramp-up process.
When emails are sent using a new platform, Internet service providers (ISPs) are suspicious of IP addresses that are not recognized. If large volumes of emails are suddenly sent, the ISPs often mark them as spam.
To avoid being marked as spam, progressively increase the volume sent using waves. This ensures smooth development of the start-up phase and reduces the overall rate of invalid addresses.
To do so, use the Schedule waves according to a calendar option. For example, set the first wave to 10%, the second to 15%, the third to 20%, and so on.
