Attentive QR Flow Doubles Opt Ins
Attentive
Attentive’s edge is not just better messaging, it is better list building at the exact moment a shopper is ready to raise a hand. On desktop, QR codes turn a dead end into the same near instant mobile signup flow, which matters because SMS growth is constrained first by consent. If TeePublic and Redbubble saw about 2x higher opt in, that means Attentive is improving the top of the funnel before any campaign, segmentation, or automation work even starts.

This is especially valuable for ecommerce brands because much of browsing still happens on desktop, while the text message itself lives on the phone. The QR bridge closes that device gap. Instead of typing a keyword or form filling, a shopper scans and lands straight in the prefilled signup path.

The strategic contrast with Klaviyo and Postscript is that all three can send SMS campaigns, but Attentive built its brand around opt in mechanics as the core product wedge. In a regulated channel where non compliant messages can trigger fines, the company that captures more explicit permission has a compounding advantage in reachable audience and send volume.

That also explains why Attentive could become a large business before broadening further. Attentive reached an estimated $200M revenue in 2022, versus Postscript at an estimated $78M in 2023, while Klaviyo scaled much larger by bundling SMS into a broader ecommerce CRM. Attentive won early by specializing in conversion at signup, then layered analytics and richer messaging on top.
Going forward, desktop to phone handoff will matter even more as inbox filtering tightens and brands need subscribers who actively opt in and save sender details. The winners in SMS and RCS will be the platforms that own consent capture, not just message sending. Attentive is positioned to keep pushing from a point solution into the control layer for mobile commerce messaging.
