Recently a change was made to how email opens where calculated in Eloqua Insight to remove discrepancies between operational reports viewed through the Eloqua client vs. when viewed in Insight. The change meant that users would see higher unique open rates than before because the calculation is now based on a wider set of touch points. An unintended side effect of this is that users may also see a high number of opens attributed to unknown visitors in cases where those visitors cannot be tied back to contacts in the database. In this case, all of those opens are attributed to a single unknown visitor, which means that it is more likely that users will see lower unique open rates than before. This change has caused a problem for many customers who look at trending data on open rates.
This change will be reverted the week of June 3rd, back to the original way of calculating open rates. This means there will occasionally be a minor difference between the open rate in an operational report viewed through the Eloqua client vs. when viewed in Insight.
A feature request has been opened to properly address the difference between the data in the operational report and Insight. This feature request is targeted to be delivered in July, 2013.
