Attentive’s Rumored Google Partnership Is Rattling the SMS-to-Search Playbook
Sources close to the matter say Attentive is in advanced talks with Google to pipe first-party SMS engagement data directly into Performance Max campaigns — a move that could redraw the CAC math for DTC brands.

Something is shifting inside the relationship between Attentive and Google’s commerce ads team, and the DTC agency world is buzzing. Multiple sources close to the matter — including two agency partners who work with both platforms — say that Attentive has been in discussions with Google’s Performance Max product team since at least Q1 2026, with the goal of enabling SMS engagement signals (open rates, click behavior, purchase intent flags) to feed directly into PMax audience scoring. If the integration ships as reportedly scoped, it would be among the most significant first-party data plays in the SMS marketing category since Klaviyo’s CDP pivot last year.
Neither Attentive nor Google has confirmed anything publicly. When reached for comment, an Attentive spokesperson said only that the company “continues to invest in ecosystem partnerships that drive measurable outcomes for customers.” Google declined to comment. But the rumors are specific enough — and sourced closely enough — that agencies and brand operators are already gaming out what it would mean for their 2026 media mix.

What Exactly Is the Alleged Attentive-Google Integration?
According to two sources familiar with the alleged discussions, the integration would work through a combination of Attentive’s existing Customer Data Platform layer and Google’s Customer Match API. The unconfirmed proposal would allow brands to surface SMS-identified high-intent segments — users who clicked a cart-abandonment SMS, for instance, or who responded to a browse-abandonment trigger — as suppression or amplification audiences inside PMax campaigns.
That’s a meaningful capability gap today. Right now, most DTC brands running PMax alongside Attentive are doing manual list exports on weekly or bi-weekly cadences, a workflow that leaks signal decay badly. If the integration is real and ships with near-real-time syncing, the effective audience freshness could move from days to hours.
“If Attentive can close the loop between an SMS click at 9pm and a PMax bid adjustment by 9:15, that’s a fundamentally different CAC conversation. We’ve been waiting for someone to own that handoff,” said Taylor Morin, growth director at Oddit, the conversion rate optimization studio that works with over 200 Shopify brands.

Oddit is reportedly already piloting a “signal stack” strategy with select clients that pre-positions them to take advantage of the integration if it launches before Q3. Morin declined to confirm whether Attentive had briefed Oddit directly.
Why Is This Rattling Klaviyo and Postscript?
The alleged Google partnership would be a direct shot at Klaviyo’s positioning as the default first-party data spine for Shopify brands. Klaviyo has spent the last 18 months building out its CDP layer — a move widely interpreted as an attempt to become the central data hub that other ad platforms pull from, rather than a downstream recipient. If Attentive lands a direct Google integration, it undercuts that narrative hard.
Sources say Klaviyo’s partnerships team is aware of the rumored Attentive-Google talks and has accelerated its own conversations with Google Shopping’s feed optimization team. One source described internal Klaviyo messaging as “we’re not going to let Attentive own the paid search handoff.” Klaviyo did not respond to a request for comment by press time.
Postscript, the smaller SMS platform that has carved out a strong position among Shopify-native brands doing under $50M in revenue, faces a different kind of pressure. Postscript’s core differentiator has been its deep Shopify Flow integration and its focus on conversational SMS. A Google signal integration is outside its current product roadmap, according to one agency source who works closely with Postscript’s partner team.
“Postscript is great at the Shopify-native layer. But if the signal race moves to paid media integration, they’re going to need a PMax story fast. Right now they don’t have one,” said one agency operator who asked not to be named because of active vendor relationships.
Who at Attentive Is Reportedly Driving the Google Push?
Multiple sources point to Amit Jhawar, Attentive’s President, as the executive most closely tied to the reported Google discussions. Jhawar, who joined Attentive in 2023 after a long tenure at Braintree and a stint at Venmo, has been publicly vocal about expanding Attentive’s surface area beyond owned-channel SMS into what he’s called “the full acquisition loop.” His framing at Shoptalk 2026 in March — where he said on stage that “SMS data is the most underutilized first-party signal in paid media” — now reads as something close to a product roadmap hint in retrospect.
Sources also mention Kait Stephens, co-founder of Brij (the QR-to-SMS acquisition tool that Attentive quietly acquired in late 2025), as playing a role in scoping the integration’s audience-building logic. Brij’s core technology converts offline and packaging touchpoints into SMS opt-ins — meaning the potential audience pool feeding into a Google Customer Match sync could include in-store and unboxing-captured subscribers, not just digital. That offline-to-paid-search loop would be genuinely novel.
What Are DTC Agencies Actually Doing With This Information?
The agency response has been predictably bifurcated. Performance-heavy shops are leaning in. Brand-focused creative agencies are skeptical.
Common Thread Collective has reportedly briefed its media team on the unconfirmed integration and is modeling blended CAC scenarios that assume 15-22% efficiency gains on PMax if SMS-sourced audiences replace cold Google signals for mid-funnel prospecting.
Pilothouse Digital, the Victoria-based performance shop known for its DTC media work, is allegedly running an internal test using manually exported Attentive segments in PMax to baseline what an automated sync might produce. Sources say early results are “directionally positive but noisy.”
Several boutique Shopify-focused agencies told Ecommerce Times they are actively advising clients to delay SMS platform consolidation decisions — specifically the Klaviyo-vs-Attentive debate — until the partnership status is clarified.
At least one large agency holding company with a dedicated commerce practice has reportedly put Attentive back on its preferred vendor shortlist after removing it in 2025 amid concerns about pricing tier changes.
“We pulled back on Attentive recommendations for a while. If the Google integration lands the way people are describing it, that calculus changes completely. First-party signal scarcity is the defining challenge in paid right now,” said one commerce practice lead at a network agency, speaking on background.
Is There a TikTok Shop Angle to This Story?
Interestingly, yes — and this is where the gossip gets more layered. Sources close to the matter say that part of the urgency behind Attentive’s reported Google outreach is a defensive response to TikTok Shop’s increasingly aggressive first-party data story. TikTok Shop has been pitching brands on a closed-loop model where purchase behavior inside the app feeds directly back into TikTok’s ad targeting, effectively making external SMS and email data less necessary for re-engagement on that platform.
For brands doing significant volume on TikTok Shop — reportedly north of 30% of GMV for some DTC apparel and beauty brands in 2026 — the pitch is seductive: why pay for an SMS platform if TikTok already knows who bought? Attentive’s alleged counter-move is to demonstrate that SMS-sourced signals are still superior for cross-platform re-engagement, particularly on Google Search and Shopping, where TikTok’s data doesn’t reach.
It’s a classic platform arms race, and the brands caught in the middle are being forced to make infrastructure bets they’d rather not make in a year when ad budgets are already under pressure.
What Should Operators Actually Watch For?
Until an official announcement drops, operators should treat everything above as unconfirmed. But here’s what several sources suggest watching as leading indicators:
Attentive’s next product announcement cycle: The company has historically used its annual Summit event to debut major integrations. The 2026 Summit is reportedly slated for late September. If the Google integration is real and on track, an announcement window there would make strategic sense.
Google’s Performance Max changelog: Any Customer Match API expansion that broadens eligible data sources could be an upstream enabler of the rumored integration, even before Attentive announces anything.
Klaviyo’s partner conference positioning: If Klaviyo moves to announce its own Google Shopping integration at or before Attentive’s Summit, it’s a strong signal the competitive intelligence is real.
Attentive pricing tier changes: Two sources suggest the integration, if it ships, will be gated behind Attentive’s enterprise tier, potentially re-igniting the pricing controversy that cost the platform mid-market accounts in 2025.
The bottom line for operators: the SMS-to-paid-media integration race is real, the timing is accelerating, and the platform you choose for owned-channel communication is increasingly also a decision about your paid media data infrastructure. That’s a different buying conversation than it was 18 months ago — and it’s one worth having before Q4 budgets get locked.
