Overview

The global control group is a list of users who will not receive any of your marketing campaigns. It is a strategically selected subset of the entire user base that is intentionally excluded from receiving any marketing campaigns across all available channels. For more information, refer to Control Groups.

The global control group is established at the account level, encompassing a segment of your entire user base. You can create only one global control group for each workspace. This group remains consistently excluded from all marketing campaigns across all channels and campaign types. Its primary objective is to provide a holistic, account-wide benchmark for measuring the overall incremental impact of your marketing activities.

The concurrent execution of numerous marketing campaigns introduces a challenge in accurately quantifying the incremental uplift attributable to specific initiatives. While an end-user may be intentionally excluded from receiving communication within one particular campaign (via a campaign-level control group), they may still be exposed to and influenced by communications from other simultaneously active campaigns, potentially leading to conversion. Consequently, to obtain a precise measurement of the true overall impact of marketing efforts, a global-level control group is necessary. This group, by design, remains entirely unexposed to any campaign communication, providing a reliable baseline for comparison and enabling the accurate determination of actual uplift.

Enable the Global Control Group

1. On the left navigation menu in your MoEngage dashboard, click Settings > Advanced settings > Control groups. The Control groups page appears.
2. In the Global control group section, turn the Status toggle on to enable the global control group.
   The global control group is enabled for the current workspace. A confirmation message appears in the lower-right corner.
   
3. Click Edit to add details to the global control group. The following page appears, where you can define the control group:
   
4. You can create global control groups in two ways:
   • Random Allocation: This method randomly allocates a fixed percentage of all your users to the global control group.
     1. Click the Random allocation option.
     2. In the text box below, type the percentage of all users whom you want to be allocated to the global control group.
        
        

        info

        Information When the global control group is created with random allocation, it is created for all the users in the workspace at that time. For example, if a control group is defined as having 10% of all users, one in every 10 users will be a part of this control group. The user allocation to the global control group is completely random. New users who are added to the workspace after the control group is created will also be included in the group, as per the defined percentage of all users in the random allocation. That is, one in every 10 new users will be included in the control group.

   • Uploading user list: In this method, you can upload a CSV file with a list of user IDs to create the global control group. All the users in the list will be added to the control group automatically.
     1. Click the Upload users list option.
     2. Click Upload file or drag and drop here to upload your CSV file.
        
        Note: You can upload only a CSV file. The maximum file size for upload is 50 MB.
5. Select the Apply global control group in all existing campaigns check box if you want to apply the global control group to all existing campaigns. This will impact the existing scheduled or upcoming periodic campaigns.
   
6. Select the Allow marketers to send campaigns to these users check box if you want to allow marketers to decide during campaign creation whether to send campaigns to the users in the global control group. This is particularly useful when sending transaction communications or important messages such as mandatory app updates.
   By default, the global control group applies to all new campaigns. Selecting this check box will allow marketers to decide whether to use the control group when creating campaigns.
   
7. Click Save changes. The Save changes to control group pop-up window appears, prompting you for confirmation. After you save the changes, they will be applicable to all the existing campaigns.
8. Click Confirm.

   info

   Information On completion of global control group creation, the system may take up to 24 hours to enable your global control group. You will be notified as soon as your control group is ready for use. When a user is added to a control group, MoEngage raises an event named User added to control group with the attribute Control Group type, which has the value Global. If the campaign qualifies a very small user base, there may be a condition that no user from the qualified user base is a part of the global control group. In that case, MoEngage will not showcase the control group stats for that campaign in Uplift.

9. Click Download users to download all users in the global control group. MoEngage generates a report and sends to your email ID.
   
10. To delete a control group:
    1. Click Delete. The Delete control group pop-up window appears, prompting you for confirmation. After you delete a control group, MoEngage releases all its users. They will start receiving campaign messages henceforth.
       
    2. Click Delete for confirmation.

Disable the Global Control Group

After you have enabled the global control group for a workspace, you can disable it anytime.

1. On the left navigation menu in your MoEngage dashboard, click Settings > Advanced settings > Control groups. The Control groups page appears.
2. In the Global control group section, turn the Status toggle off to disable the global control group.
   The global control group is disabled for the current workspace. A confirmation message appears in the lower-right corner.
   

When you disable the global control group, the users who were part of it will start receiving campaigns. This will impact the existing scheduled or upcoming periodic campaigns.
