Attentive Enhances Two-Tap(TM) and Adds New Omnichannel Tools to Boost Subscriber Growth, Visibility and Compliance

Attentive enhances Two-Tap(TM) and adds new omnichannel tools to boost subscriber growth, visibility and compliance. Attentive has expanded its patented Two-Tap(TM) engagement technology - originally focused on mobile - to now include desktop experiences, enabling brands to capture previously missed web traffic and convert it into high-quality mobile subscribers through a simple QR-based opt-in flow, significantly increasing owned audience growth potential. Alongside this extension, Attentive unveiled a suite of new capabilities designed to help marketers navigate evolving inbox behaviours and compliance challenges driven by changes such as iOS 26 inbox filtering, where filtered messages can see substantially lower engagement, and tightening SMS regulations. These enhancements allow brands to unlock several tools for reach protection and expansion across channels. They include inbox visibility tools that identify potential messages and apply fixes for improved delivery, barcode tools that connect email engagement with in-store shopping, and audience sizing tools that allow for enhanced targeting. Automated quiet hours based on location simplify compliance, while AI-powered campaign optimization and template tools reduce effort and improve performance. Additionally, the company's expansion into first-party data within SMS, email, push, ads, and loyalty continues to emphasize the importance of mobile identity-based engagement. Altogether, these innovations are designed to allow brands to protect reach, expand their subscriber base, and comply in an evolving marketing landscape. MarTech360 Bureau 1172 posts 0 comments
