Ease of Use

The set-up was easy to use and the real-time personalization was great for engagement and click-through rates.

Specific Use Cases

We use the countdown a lot, since we use F1 events a lot, so we have this countdown to let the user know that the Grand Prix they want to see is coming.

From 16 reviews | Last Published May 28, 2026

Reviewers indicate that Litmus from Validity significantly enhances email marketing strategy by providing granular insights into recipient behavior and informing design decisions. A substantial portion of reviewers, 31%, highlighted how Litmus offers a more comprehensive understanding of email engagement beyond basic opens and clicks, including reading time, device usage, and heatmaps. These deeper metrics enable organizations to refine content, optimize calls to action, and prevent future issues, thereby improving overall reporting and campaign effectiveness.

This capability helps creative teams refine designs for better user experience and supports the development of responsive email templates, which is particularly crucial for mobile users. The insights gained from Litmus empower organizations to build more effective relationships with their audience through purposely connected and engaging campaigns.

Email engagement insights

Litmus offered us a more in-depth overview of how people genuinely engage with our email campaigns. They show us not just opens and clicks; they also share reading time, device usage, and heatmaps of how attention is directed so we can better understand things like when subject lines were too long, when content could be edited down, and when the best place for the calls to action were within the body of the email. Really, what they have done is taken the guesswork out of email marketing and helped us build relationships with campaigns that are purposely connected, interesting, and convert.

Informing design and strategy

Litmus was pivotal when marketing responsive design to my clients. I needed proof that subscribers were using cell phones more often to view emails. Litmus reporting was able to provide the proof. Since then, I have collaborated with designers to create with mobile in mind first. Responsive design not only improved engagement for subscribers but it also strengthened my relationship with my clients. Now that responsive design is the norm having access to interactive content builders has allowed me to expand my capabilities and provide exciting use-case ideas to my clients.
