Activation Explainers
Activation History shows a table with the entire activation history for a client.
The icon to the left of the name shows the status of the most recent send for that Activation.
Activation can be deployed multiple times. (i.e. the audience probably gets re-deployed after every update) Simply, a send is an instance of an activation. By clicking on the activation name, you can view send history per activation.
Destination shows where the audience was deployed to:
Facebook
Google Ads
Snapchat
Twitter
Linkedin
Google CMU (Customer Match Upload)
etc
The CRM List column distinguishes where the deployed audience came from. This is most useful when deploying segments.
Size vs. Members Sent: These should match. Size represents the number of rows we have stored for an audience. Members Sent represents the number of rows that were successfully sent to the deployment source.
The Last Send column shows the date and time of the most recent send.
If these numbers are drastically different, that may indicate an error in the deployment. See Troubleshooting Deployment Errors for help.
