Here are some tips to help you troubleshoot campaign reports in Blueshift.

Campaign performance report

Q. Why is the Unique open rate for a particular trigger in the campaign is greater than 100%?

The Unique open rate is calculated as unique impressions/delivered in percentage format. 

  • Consider that you have a campaign that has sent “X” messages in week 1 and “Y” messages in week 2. 
  • If you look at the metrics for week 2, you see that the delivered messages for week 2 are Y-n and the unique impressions for that week are Y-n+Z which is greater than the number of messages delivered. (“n” is messages that were sent but not delivered).

This is possible if some of the unique impressions are for messages that were delivered in week 1 but were opened by customers in week 2. If you look at a broader time period or for the time period of the entire campaign, you will see a more accurate unique open rate.

Q. Why doesn't the campaign performance report show any data for the campaign but the campaign index page shows metrics for the campaign?

  • Verify that you have selected the correct date range for the campaign performance report. 
  • If you have multiple channels in the campaign, verify that you are selecting the right channel.
  • Check if the triggers that were used to send the messages are active or are archived and select the filter options accordingly.

Campaign Engagement report

Q. Why is there a difference found in the unique clicks in the Campaign Engagement report and the external tool we are using?

Blueshift uses the HyperLogLog algorithm for estimating unique impressions and unique clicks. This algorithm has an accuracy of 98%, which means that results will be within a 2% error margin. The external tool that you are using might also have a certain margin of error. The observed difference in the unique clicks could be due to this.
