The Challenge

A licensed Brooklyn dispensary had a growing customer list but zero post-purchase follow-up. Every transaction ended with no re-engagement. The question: design a single post-purchase SMS campaign, measure the revenue impact with strict attribution, and determine whether post-purchase SMS deserved a permanent place in the marketing stack.

What We Did

How we did it.

    Identify the Post-Purchase Window

    We isolated customers who purchased within the previous 7 to 14 days with no follow-up communication. This window captures buyers while purchase intent is highest and brand recall is still fresh.

    Write One Specific Message

    A single SMS. Short, direct, and tied to the recipient's purchase category. No generic blast. The message referenced a complementary product type or a loyalty point balance update to create a personalized feel within OCM compliance guardrails.

    Deploy at Optimal Send Time

    Campaign launched Tuesday afternoon between 2 and 4 PM, the highest-converting send window for dispensary SMS. Avoiding mornings, evenings, and weekends maximized conversion intent while minimizing unsubscribe risk.

    Measure With Strict Attribution

    Revenue attributed only to recipients who engaged with the campaign. No incidental visits counted. The $17,324 figure is conservative by design; actual influence is likely higher but undocumentable with strict attribution methodology.
