The new call campaign throttling feature enables the campaign managers to control the number of calls triggered by the campaigns per minute. 

  • Campaign Level Throttle limit- This is the throttle limit applied at the Campaign service level. All the campaigns in an account are rate limited with a value under which the call campaigns happen. For example, if it is set at 200, then a max of 200 calls will be triggered per minute by combining all call campaigns. The feature would allow the campaign managers to increase or decrease this value. 

  • Per Campaign Throttle: Campaign managers will also be able to set throttle limits for individual campaigns while creating a campaign. This value should be less than the Campaign level throttle ( configured on the setting page). Also, the combined throttle of all campaigns that are running at the same time should also be less than the Campaign level throttle. For example, if the Campaign level throttle is 200, then the combined value of individual campaigns throttle at a given time should be less than 200. 

Campaign Level Throttle Limit 

  1. The new campaigns(Campaign new) option can be found under tools. Once you click on it, you can find a “Settings” page as highlighted in the screenshot. You can edit/view your call throttling for your account from this page. 

  2. On this page, you can view your Campaign level throttle limit. 


  1. By default, the campaign throttle limit is 60 calls per minute(CPM). The campaign manager will be able to increase this value from 60 CPM to 200 CPM as shown below. 

  1. Once the value is set, please select the option save and the value for the campaign level throttle limit will be set. 

  2. Please reach out to your account manager if you want to increase this value beyond 200. Once it is approved by the account managers, you can check the updated value here.

Set campaign throttle limit

1) You will have the option to define the individual campaign throttle limits while creating a new campaign

2) When creating a call campaign as shown in the screenshot below you can select any 2 options i.e Auto or Custom CPM. The default value is Auto.

Auto -

  • In Auto mode, the CPM value is equally divided by the number of campaigns that are triggered. 

For ex: With 100 CPM if 4 campaigns of triggered in auto mode, each campaign will be triggered at ~25 CPM, with equal distribution of the CPM value. 

Please note- The calls per minute value is subjective to the quality of numbers being used, typically with good quality leads(valid, reachable numbers) the CPM holds good. However, the CPM would not vary by a huge margin. 

Custom CPM - 

  • You can set the campaign CPM value as shown below. The Available range will be visible for you to set. 

  • The CPM value should be chosen carefully, if you exhaust all the CPM, then you wouldn’t be able to schedule a campaign under Custom mode. 

  • Make sure at any given time, the aggregated values of all campaign throttle are lesser than Campaign level throttle.

3) View Custom CPM for a campaign - You will be able to view the CPM value and the campaign mode under the campaign details tab. As shown below in the screenshot. 

We hope, with this feature, we elevate your experience of using the call campaign.
