Remi Increased SMS Conversion Rate 4.7x and ROI 5.8x Using Personalized Voice Messaging
The Problem
Remi is a direct-to-consumer brand known for custom mouth guards and teeth whitening kits. While their initial SMS program performed well, engagement eventually plateaued—leading to missed opportunities for retention and growth.
Remi needed a more personal way to deepen customer relationships and encourage repeat purchases, especially within their unique subscription cycle.
It’s important to stand out in a product category like ours and we do so by building real personal relationships with our customers.
— Oscar Adelman, Founder and CEO @ Remi
The Solution
Remi partnered with Para to introduce AI-powered voice messaging into their SMS workflow. Over an 81-day A/B test, subscribers were split into two groups:
- 68% received a standard two-message text series
- 32% received a personalized voice message delivered 24 hours after the initial SMS
The voice message, recorded by Founder and CEO Oscar Adelman, was personalized with each recipient’s name and included a 40% off coupon—mirroring the offer in the text series but delivered in a more human, engaging format.
We wanted the voice message to feel personal, as though I was speaking directly to each customer. That direct connection was key to our strategy.
— Oscar Adelman
I was concerned at first about segmentation, but the integration with Klaviyo made it incredibly easy to set up and send campaigns to the right audiences.
— Daniel Rigby, Retention Marketing Lead @ Remi
The Result
Remi’s voice messaging campaign delivered significant improvements across every key metric:
- 2.0x higher click-through rate (CTR)
- 4.7x higher conversion rate (CVR)
- 9.0x more earnings per message (EPM)
- 5.8x higher return on investment (ROI)
The revenue from voice messaging exceeded our expectations. The ROI was so strong that we now often ask ourselves, should we use Para instead of SMS?
— Daniel Rigby
The campaign was so effective that Remi made voice messaging a permanent part of their strategy, integrating it into their broader communication efforts.
Final Thoughts from Remi
Voice messaging helped Remi not just boost performance—but reimagine how they build relationships throughout the customer lifecycle.
Voice isn’t just helping us now—it’s part of our strategy moving forward. We’re excited to use it across the entire customer journey, from acquisition to retention.
