Post-Purchase SMS: 266,016% ROI Case Study

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

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.

Key Takeaways

Post-purchase is the highest-ROI send window. Recent buyers have the strongest repurchase intent of any segment. Reaching them within 7 to 14 days of purchase captures that intent before it fades to baseline.
The cost of not following up is measurable. At $6.32 per message in attributed revenue, every SMS not sent to a recent buyer is a quantifiable missed opportunity. Silence is not free.
266,016% ROI from a $6.51 investment. The total send cost was $6.51. The return was $17,324. This is the efficiency ceiling that makes SMS the highest-ROI channel in cannabis marketing when executed correctly.
Strict attribution understates impact. These numbers count only engaged campaign recipients. Real influence extends to recipients who saw the message and visited without clicking. The documented number is the floor, not the ceiling.
