While Litmus offers several benefits, there are some areas where its accuracy and performance can be limited:Image Loading and Email Clients

Some email clients block external images or are not capable of displaying HTML emails, affecting the accuracy of open rate metrics.Data Privacy and Apple’s Mail Privacy Protection
Litmus has to account for data privacy measures, such as Apple’s Mail Privacy Protection, which can impact the accuracy of open rate data. However, Litmus automatically filters out opens impacted by these measures to provide more accurate engagement data.Human Supervision for AI-Generated Content
While AI is powerful, it sometimes requires human supervision to ensure functionality across different settings (like Dark Mode) and to meet accessibility standards. This is particularly relevant when AI is used to generate code or imagery for emails.Areas for Improvement
Forward and Print Data
Litmus no longer provides reliable forward or print data for any inbox provider due to privacy standards and accuracy concerns. This limitation can affect the completeness of email analytics.AI Biases and Privacy
The use of AI tools, including those in Litmus, can introduce biases and raise privacy concerns. Marketers need to be cautious about how AI-generated content and chatbots collect and use data. In summary, Litmus is a powerful tool for marketers, offering significant benefits in email analytics, automation, and collaboration. However, it has limitations related to image loading, data privacy, and the need for human supervision in certain AI-generated content. These factors should be considered when evaluating its performance and accuracy.
