Inside from Litmus research

Verify emails on different devices and applications. I check also HTML reviews with different email templates. we use several markets and brands for each brand has a different type of email. All those emails need to be checked whether their layout , fonts, and format are correctly implemented. here are the points.

improve campaign performance: its greatly improved our understanding of how our email campaigns are performing. This data-driven allowed us to optimize our email content, design, and targeting strategies, resulting in improved campaign performance and higher engagement. we can prioritize our testing approach based on engagement patterns and subscriber behaviors. we focus on testing the element and scenarios that are most critical for user engagement and conversations.

I give from Real-time preview and testing: before using Litmus, we had manually tested emails across various email clients, devices, and platforms which has time-consuming and prone to human error. however, with Litmus, we can preview and tests the emails in real-time across multiple environments and application simultaneously. this has significantly reduced our testing effort and accelerated the QA process.
