Enterprise retail brand goes live in 10 weeks
The challenge
A major retail brand needed to migrate from a legacy ESP to Marketing Cloud ahead of peak trading season, with a hard deadline and a complex loyalty data model.
Our approach
We ran a compressed discovery sprint to map the data model, built a phased migration plan that kept existing campaigns live throughout, and delivered a parallel-run testing period to validate every journey before cutover.
The outcome
Went live 2 days ahead of schedule. Zero campaign disruption during peak. Email revenue up 34% in the first quarter post-migration.
