Case Study: Grubhub achieves 97% faster email production and frees designers from HTML with stensul

How Grubhub Saved Its Creative Team From Code

GrubHub, the Chicago-based online and mobile takeout marketplace, faced a slow, error-prone email production process that relied on hand-coding and hard-to-use ESP templates. The B2B marketing and creative teams needed to get designers out of HTML, shorten turnaround, and scale email campaigns—so they adopted stensul’s email creation platform to streamline design-to-deployment.

Using stensul, GrubHub eliminated developer bottlenecks and cut production friction, enabling full email campaigns to be created in less than a day without touching HTML. The move delivered measurable impact: a 97% decrease in total creation time, 86% less production time, 25% fewer people involved, and 100% of QA hours saved, while improving ESP compatibility and enabling faster last‑minute edits.
