Styrkr

Fuel for endurance athletes. PLAT runs the email engine — a rebuilt flow programme, a weekly campaign engine, and launch support for CEL50 energy chews.

Styrkr makes fuelling products for endurance athletes — and its audience reads, trains, and buys with intent. PLAT took over the email programme in 2026: a rebuilt welcome series, a weekly campaign engine with formats that compound week over week, and disciplined reporting where every send is measured against store revenue, not vanity metrics.

When Styrkr launched CEL50 energy chews, PLAT ran the email side of the launch — teaser, launch and follow-up campaigns built around the product story.

The giveaway week — engineered without a single discount — finished statistically level with the brand's best discount weeks, at full margin. The maturation model behind the weekly reporting projected the result within range before it landed: predictive, not descriptive.
