It will take a bit of time until the statistics from the campaign is updated. So grab a coffee and check back in a bit later. From the campaigns menu, you can see all the launched campaigns and also the high-level results.
Click the specific campaign and select "Results" to see more details. The statistics will update over time.
Beware that not all email clients will report "open"-actions, so this metric will be lower than the actual open rates.
To see engagement for specific recipients, click "Recipients".
Here it is possible to filter on specific actions, making it easy to find who clicked the CTA directly.
