About GURU Beverage
GURU Beverage is a leading energy drink company known for their clean ingredients, plant-based formulations, and sustainability-first mindset. Founded in Montreal, GURU’s mission is to offer a healthier alternative to conventional energy drinks by using organic ingredients and natural caffeine sources.
With distribution across North America and a growing DTC channel, the brand’s success is built on authenticity and transparency. GURU’s audience values function and purpose, expecting brands to deliver both performance and integrity. As their digital presence grew, so did the need for a scalable review system that aligned with their minimalist team and performance-driven ethos.
Partnering with Thails — a Shopify Plus agency specializing in conversion and retention — GURU sought to enhance its post-purchase experience through authentic, high-performing customer reviews.
Challenges
Before partnering with Stamped — a move recommended and led by Thails — GURU Beverage faced three core challenges:
- Low review volume limited their ability to showcase customer trust and feedback at scale
- Inefficient systems from their previous provider were costly and difficult to manage for a lean marketing team
- Lack of incentivization meant customers had little motivation to submit high-quality, actionable reviews after making a purchase
“Our decision to switch was primarily cost-driven — our previous [review solution] was no longer a sustainable solution for a lean, fast-moving team like ours. The transition to Stamped was smooth and straightforward, with very little disruption to our workflows.”

Solutions
GURU Beverage partnered with Thails, a Shopify Plus agency specializing in conversion and retention optimization, to implement Stamped Reviews. Together, they developed a scalable, automated review strategy that required minimal hands-on management from the brand.
With Stamped Reviews, GURU was able to:
- Migrate seamlessly from their previous reviews provider to Stamped without operational downtime
- Embed in-email review collection directly within their post-purchase flow, making it effortless for customers to leave feedback without leaving their inbox
- Incentivize reviews with a $5 off coupon, driving both engagement and repeat purchases
- Leverage automation for moderation and publishing, freeing the team from manual review management
“Collecting reviews directly through email, paired with the $5 incentive, has had a real impact. We’re seeing more customers engaging, leaving higher-quality reviews, and providing useful feedback we can act on. It’s helped us build both trust and social proof in a way that feels authentic.”

Results
The implementation of Stamped for reviews, powered by Thails’ lifecycle strategy, delivered immediate performance gains:
- 53% open rate on review request emails (well above the 30–35% industry benchmark)
- 7% review submission rate, more than double the category average of 2–3%
- Higher-quality reviews and actionable feedback improving overall customer experience insights
“For any lean team considering Stamped, we’d say it’s a great solution. It’s cost-effective, easy to manage, and delivers results without needing a big internal lift.”

The Thails Perspective
As a Shopify Plus agency partner, Thails saw Stamped as a direct enabler of better post-purchase engagement. Their role centered on implementation, optimization, and strategy execution.
- Their goal: To close the gap between purchase and feedback, helping brands like GURU scale authentic UGC without added complexity
- Stamped’s impact: Accelerated review generation and stronger post-purchase engagement
- Outcome: Simplicity, automation, and measurable ROI that can be replicated across more client brands
“Our goal was to make reviews feel like a natural part of the post-purchase experience, not an afterthought. Stamped gave us the flexibility to do that while keeping automation and brand consistency front and center.”

What’s Next?
GURU plans to extend its partnership with Thails and Stamped into Loyalty and Retention initiatives, using customer reviews as the foundation for stronger community engagement. The simplicity of Stamped’s automation has given GURU’s small team the bandwidth to focus on strategic growth rather than manual operations.
