How Carpe Boosted SMS Conversions by 119% with Littledata + Attentive
Introduction
Carpe is a fast-growing DTC brand offering dermatologist-recommended sweat and odor management products. Founded by two college friends frustrated by ineffective treatments, Carpe’s mission is to help people live confidently with simple, science-backed solutions.
With a growing Shopify-powered storefront in the US and UK, Carpe relies on personalized email and SMS journeys to engage its loyal customer base.
Challenge
As Carpe scaled its retention efforts across email and SMS, the team saw gaps in performance due to limitations in tracking and identity resolution. Users often signed up for a discount or browsed the site, but returned later on different devices, resulting in lost attribution, incomplete abandonment flows, and missed re-engagement opportunities.
Attentive was already a key part of Carpe’s retention stack, powering their SMS journeys, including browse and cart abandonment. However, key user behaviors, like product views and add-to-cart events, were not being reliably tracked due to common issues with first-party tracking like Safari ITP, cookie opt-outs, and ad blockers. This meant many high-intent users were falling out of SMS journeys before they could be re-engaged.
To fully unlock the value of Attentive, Carpe needed a solution that could persist user identity across sessions and improve visibility into pre-purchase actions. They partnered with Littledata to close the data gap and drive smarter SMS performance without added engineering work.

Solution
Carpe implemented Littledata’s Attentive integration. A server-side, no-code solution that enriches Attentive with accurate pre-purchase tracking and persistent identity resolution. This enabled Carpe to:
- Capture key events like Product Viewed and Add to Cart using server-side tracking, bypassing browser limitations and ad blockers
- Stitch together user activity across sessions using email clicks, form submissions, Shopify cookies, device fingerprints, and IP data
- Automatically feed identified users into Attentive’s browse and cart abandonment flows, even if users returned hours or days later
- Maintain real-time audience syncing between Klaviyo and Attentive, ensuring coordinated outreach across email and SMS channels
With Littledata acting as a unified tracking layer, Carpe could recognize more shoppers after opt-in, and Attentive could trigger more personalized journeys with higher match rates and stronger results.
Results
In their first two months with Littledata, Carpe achieved:
- +112% increase in SMS deliveries (290,233 vs. 137,052)
- +119% increase in conversions (1,714 vs. 781)
- +80% lift in journey conversion rate (7.11% vs. 3.96%)
These results were achieved with no changes to offer, creative, or audience strategy. Only by enabling smarter, server-side identity resolution through Littledata did Carpe unlock the full potential of Attentive’s AI journey builder.
