Case Study: The Sandbox Agency achieves unified rebrand consistency and 2.4M contacts reached with Sigstr

The Sandbox Agency - Customer Case Study

The Sandbox Agency, an independent middle‑market advertising firm with eight offices across the U.S. and Canada, faced a major rebrand after integrating several agencies and needed to present a single, consistent identity in every market and outgoing communication. To achieve unified, one‑to‑one messaging during the transition, The Sandbox Agency partnered with Sigstr and adopted Sigstr’s email signature marketing platform as a dependable branding mechanism.

Sigstr rolled out a company‑wide signature and banner campaign (initially onboarding 381 employees) that standardized sign‑offs and added a rebrand banner linking to Sandbox’s homepage; the campaign reached more than 2.4 million contacts and generated 5,784 banner clicks. The Sandbox Agency has continued using Sigstr to announce acquisitions and events — including a #MissingType awareness push that earned 55,000 views in four days — showing clear, measurable increases in brand reach and engagement.
