The Challenge

Trendline Interactive and its clients have high expectations for the quality of their emails. That’s why email testing and quality assurance (QA) play a crucial role in the agency’s email workflow. Every single email must pass a rigorous QA process, where the team checks everything from content and spelling to tracking codes, links, images, and whether the email renders correctly in different environments. While this step is crucial to guarantee email quality, it’s also a time-intensive one. Streamlining the QA process while maintaining low error rates is a key challenge for Molly Privratsky, VP of Email Operations and head of the QA team at Trendline Interactive.

How Litmus Solved the Challenge

Litmus Email Analytics enables Trendline Interactive to better understand which email apps and devices their clients’ subscribers use to read email—and that helps set priorities for email development and troubleshooting. With clear insights into which email environments matter most to the target audience, the team can focus their optimization efforts on the most critical email clients, and spend less time on those that aren’t relevant to the client’s subscriber base.

With Litmus, Trendline Interactive also automates large portions of their testing efforts to reduce overall testing times. Litmus Email Previews allow the team to test their designs in all popular email clients and devices and make sure they look great everywhere, without having to manually check a large set of test accounts on individual devices.
