Case Study: Zen Internet achieves 90% less email testing time and higher click-through rates with Litmus

Zen Internet spends 90% less time testing emails and doubles their click-through rate with Litmus

Zen Internet, a UK-based internet service provider, needed a faster, more reliable way to test, review, and approve a high volume of marketing emails while maintaining strong quality standards across its email program. The team, led by CRM Marketing Manager Lucy Schofield, was spending too much time on manual feedback and approval processes and needed a solution that could support best practices and dynamic content testing. Litmus helped Zen Internet streamline its email workflow with its Salesforce Marketing Cloud integrations and email testing tools.

Using Litmus Email Previews, Litmus Extension, Litmus Email Guardian, Litmus Proof, and Litmus Email Analytics, Zen Internet improved collaboration, caught errors before send, and gained better insight into subscriber engagement. The results were significant: testing and approval time dropped from an hour to 10 minutes per email, saving 50 minutes per email, and the team doubled newsletter click-through rate from 0.91% to 2.2% with Litmus Personalize. Litmus also helped them catch a broken link before it reached subscribers, protecting the customer experience.
