Case Study: iZotope achieves faster email workflows and trims days off review time with Litmus

How iZotope shaves days off their email workflow with Litmus

iZotope, a maker of intelligent audio tools for musicians and engineers, relies heavily on email to engage and educate more than one million subscribers—sending about 16 campaigns a month. Their small core team (four marketers, with ~20 reviewers involved per send) struggled with a fragmented QA and review process: copy, design, and pre‑send checks produced feedback through Google Docs, Sheets, long email threads, and Slack, creating repeated rework and slow approvals.

Implementing Litmus gave iZotope a single platform for automated previews across 100+ email clients, accessibility and load checks, and collaborative feedback through Litmus Proof. Fast onboarding meant immediate benefits: more thorough testing, a consolidated review workflow, and fewer review cycles. As a result, their end‑to‑end email production time dropped from a 4–6 day review phase to an average total workflow of 4 days, improving subscriber experience and internal efficiency.
