Litmus' Story


Litmus offers a web-based email creation, testing, and analytics platform that empowers marketers to confidently deliver a superior subscriber experience. Litmus has partnered with more than 250 major email service providers and agencies, including MailChimp and IBM Silverpop to help users quickly and easily build, test, troubleshoot, and optimize campaigns.  

Litmus has been profitable, since their inception in 2005, according to Litmus CEO Paul Farnell. Still, it was, presumably, a welcome development when, in October 2015, Litmus received $49M in funding from Spectrum Equity. With this funding, Litmus announced plans to use this money for innovation and to support their planned international expansion and service.

As Litmus continued to grow and expand their platform, they were outgrowing their in-house built billing system. They needed to automate back-end billing processes. And, looking ahead, they had aspirations to quickly roll out and test new pricing and packaging strategies to enable international growth and reduce customer churn.

Zuora was the flexible solution to support their go-to-market strategy.

Zuora now supports the range of Litmus packages from basic to Pro, API, and Enterprise. Zuora also helps Litmus run daily bill runs, managing for the complexity of flat fees combined with usage charges. With Zuora, upgrades are effective immediately and Litmus can give prorated refunds on downgrades and cancellations. All of this immediate response leads to an improved customer experience.

Looking ahead to future phases of global expansion, Litmus plans to roll out new currencies and new pricing schemes. The Zuora platform will help Litmus to iterate on pricing as they scale internationally. And, with Zuora reporting, the Litmus finance team can get the valuable data they need to test and refine their growth strategies.

In August 2016, Litmus announced a new partnership with Microsoft, provider of Outlook email. Litmus will be working with Microsoft Outlook’s product team to help “prioritize email rendering bugs in Outlook, identify issues faster, and announce improvements and fixes to the community.” This partnership is yet another exciting development for a company on the rise.

Litmus now powers more than one million email preview tests every day and tracks over one billion email opens every month. As Farnell notes, “Email and marketing are growing spaces.”
