Performance Reporting: The Nitty Gritty of “Open Email” Activity
⚠️ This post has been edited by a moderator for clarity.
Performance reporting in Marketo plays a crucial role in analyzing and optimizing marketing campaigns. However, discrepancies in reported numbers can occur due to various factors, particularly related to the timing and order of activity logs.
During my analysis of email performance for a client, I encountered unexpected activity where active leads were marked as invalid. These were leads that were actively responding to their emails. Upon further investigation, I discovered that the leads were marked as inactive before their open activity was logged.
In my research, I came across product documentation, discussions, and similar posts where others had experienced similar issues. People shared their challenges and the solutions they implemented. In this post, I aim to compile the potential causes behind performance reporting discrepancies related to open activity and gather further insights.
- There may be a slight delay between opening the email and the activity appearing in the log.
- Marketo records an "open email” activity only when the images in the email, specifically a single-pixel tracking image, are downloaded. It's possible that recipients are receiving and viewing the emails without downloading the images, which would not be counted as an "open."
- Text-only emails, lacking images, will never generate an open activity.
- If open activity is not visible for a lead with a given Email Address, even though you believe images are being downloaded, it's important to check for another lead with the same Email Address (duplicate lead) that might be logging the activity instead.
- For certain email service providers (e.g., Outlook), many people might view the email in the preview pane instead of opening it, or they might have images turned off. In such cases, open activity will not be logged.
Segmenting leads into marketable and non-marketable categories is a good practice, but it's even more effective to enrich them with behavioral attributes.
I welcome additional thoughts and insights on this matter.
