Case Study: ThomasARTS achieves 50% faster email proofing with Litmus Proof by Litmus

ThomasARTS utilizes Litmus Proof to centralize and streamline their email review and approval process

ThomasARTS (TA) is a digital agency that blends art and science to create emotionally driven email marketing, sending millions of messages each week for clients like Aetna and Marriott. Despite their high standards for perfection, TA’s review process was slow and cumbersome — reviewers took screenshots, annotated in Adobe Acrobat, uploaded files to project management, and one person had to consolidate feedback, which cost time and risked errors.

TA implemented Litmus Proof to centralize review and approval, letting all reviewers annotate and comment directly on the same email for full visibility and faster collaboration. As a result, proofing time was cut in half, the team now produces error‑free emails more quickly, and internal buy‑in for the new process was immediate.
