How DPDP will rewrite growth playbooks for Indian brands 

India’s Digital Personal Data Protection (DPDP) Act 2025 has long been positioned as a consumer-rights legislation. But as the enforcement cycle begins, its most profound impact may not be on tech firms or policy circles but may be on the country’s marketing ecosystem. With most app SDKs still firing before consent, a clear violation under the Act, the industry faces nearly ₹250 crore in potential exposure. Reduced data pipelines, diminished attribution, collapsing lookalike models, and increased CAC for businesses with few first-party ecosystems are all immediately apparent consequences of the ripple effect.

The Act brings India closer to global privacy standards, but it also forces a fundamental reset on how digital marketing operates. For years, brands relied on abundant behavioural data, algorithmic optimisation, and low-friction targeting. The DPDP Act flips that logic entirely. Consent must now precede collection. Personal data can only be processed with clarity and purpose. And legacy workflows built on invisible data capture must be dismantled and redesigned.

Across D2C founders, CMOs, legal experts and martech leaders, the consensus is stark that the era of high-signal, low-consent marketing is ending. Efficiency, trust and compliance must now co-exist, and Indian marketing is entering a signal-light phase where legal obligations increasingly override marketing ambitions.

The End of High-Signal Marketing

The first impact is blunt. Brands that built themselves on performance marketing alone will take the hardest hit. A senior D2C marketer describes the shift candidly, noting that in countries with mature privacy cultures, “you literally have to give all their permission, fill out all the things you want them to capture, otherwise it does not happen.” That rigor hasn’t broken marketing abroad, but it has changed who survives.

In his view, the brands that relied too heavily on cheap data signals “are not really brands; they are commodities,” and may not survive a world where granular tracking becomes restricted. He adds that interruption-led advertising is the first casualty of DPDP because “push is the worst form of marketing that can possibly happen.” Instead, pull-led, ethos-driven storytelling becomes essential as brands need to draw audiences in, not chase them across the internet.

This perspective mirrors the broader industry theme. First-party relationships, organic affinity and consistent creative differentiation are no longer “brand marketing nice-to-haves,” but survival levers in a low-signal world.

Attribution Breakdown and the Rise of Data Discipline

As attribution weakens, marketers are being forced into long-postponed data discipline. Arvind Lakshmiratan, CMO of Inspira Enterprise, argues that brands can no longer depend on third-party identifiers. “The only sustainable path is strengthening first-party data, using AI to model intent without breaching consent frameworks, and adopting privacy-enhancing technologies that allow measurement without exposing personal data.”

His point signals a structural shift. Efficiency will now come from compliant intelligence, not from the volume of signals. AI will play a bigger role, but within boundaries. And clean rooms and consent stacks, formerly used only by the largest advertisers, are rapidly becoming mainstream.

Legal experts echo this transformation. Yajas Setlur, Partner at JSA Advocates & Solicitors, notes that SDKs can no longer trigger before consent, which will “break many legacy workflows.” But he stresses that early compliance is a competitive advantage, not a cost. As Indian consumers become more privacy-aware, they will “reward companies they can trust with their data and loyalty.” In his view, the initial pain is the price of a healthier, more accountable ecosystem.

Rewiring Efficiency in a Low-Signal Market

As India enters a phase where identifiers shrink and attribution weakens, the natural fear is that marketing efficiency will collapse. Yet that assumption is proving increasingly outdated. Anirudh Sanjeev, Senior VP at NewsReach India, argues that efficiency does not disappear in a low-signal world, but shifts shape entirely. He notes that even with weaker signals, efficiency “doesn’t collapse rather shifts” as brands move toward consent-first data ecosystems, stronger first-party capture and modelled measurement. In his view, incrementality testing, media mix modelling and platform-led attribution will become core instead of optional.

His assessment adds a deeper layer to the industry consensus that data discipline will replace data abundance as the foundation of performance. The brands that simplify their data supply chain and reduce their dependency on risky SDKs will stabilise faster. As Anirudh puts it, “The brands that simplify their data supply chain, cut dependency on risky software development kits, and double down on owned channels, will see that efficiency is still possible but differently built.” The market is not losing performance; it is simply rewiring under new constraints.

This shift also reinforces the growing role of first-party ecosystems and privacy-safe models. As DPDP makes pre-consent data capture non-negotiable, brands that proactively rebuild their measurement muscle will outperform those that try to hold on to the past. Signal loss is not the end of performance marketing but the beginning of a more accountable and strategically resilient era.

In Boardrooms, Compliance Finally Overtakes ROAS

The more difficult transition, however, is cultural. For decades, marketing and compliance operated in parallel lanes. Growth teams chased quarterly ROAS targets; compliance teams cleaned up after them. DPDP forces these lanes to merge.

Arvind points out that compliance must now take precedence because “consumer trust is a direct business asset and regulatory missteps carry significant financial and reputational risk.” Short-term ROAS gains driven by non-compliant targeting cannot justify long-term exposure. Trust and governance become central to brand equity.

Divye Agarwal, Co-Founder of Binge Labs, frames it slightly differently. He believes most leadership teams will aim for balance, but agrees that compliance is naturally the priority because it protects both the business and the consumer. In his experience, robust compliance frameworks ultimately improve marketing efficiency, because trust improves long-term conversion stability.

A D2C marketing leader adds another dimension of how legal frameworks inevitably limit marketing freedom but also force innovation. “We’re building our own database because that’s the most reliable, and working with players to share a data pool where we can run pilots on Meta.” He sees DPDP as another turning point similar to the cookie phase-out, challenging yet full of new opportunities for collaborative, privacy-compliant data models.

Will Privacy Tech Create a Digital Divide?

One concern among marketers is affordability. Clean rooms, consent stacks, and identity resolution systems were historically out of reach for smaller brands. But Arvind expects costs to normalise as cloud-delivered solutions scale and standardise. The differentiator, he says, won’t be money, it will be organisational maturity and the ability to embed privacy and governance from day one.

Divye believes the Indian SaaS ecosystem will respond quickly, creating more accessible tools. Short-term disparities may exist, but the industry has a long history of democratising formerly expensive technologies. Over time, privacy solutions will follow the same trajectory as martech automation by being initially elite, eventually universal.

From Precision to Principles: The New Performance Playbook

With user-level signals fading, the industry is already sketching the contours of a new performance marketing playbook. It is less granular, more creative, more dependent on owned assets, and built around compliant intent modelling.

Arvind outlines the architecture clearly. First-party ecosystems, contextual intelligence, AI-driven modelling within consent boundaries, and measurement designed with privacy in mind. Divye expects creative-led performance and stronger CRM systems to take centre stage, with incrementality replacing last-click attribution. Context, content and compliance will matter more than tracking precision.

These views also align with ground reality in D2C. Brands are aggressively expanding their CRM systems, building loyalty loops, and experimenting with privacy-safe data collaborations. The goal is not to recreate the old world of abundant signals, but to build a resilient, compliant engine for sustained growth.

A New Competitive Advantage: Trust

Legal experts highlight a point marketers sometimes overlook of compounding consumer trust. Yajas emphasises that as privacy literacy grows in India, consumers will actively choose brands that respect their data. This behaviour is already visible in global markets. The DPDP Act may accelerate the same trend in India.

What emerges is a counterintuitive insight. Compliance, once seen as a cost burden, is becoming a growth strategy. Brands that embrace DPDP early will stabilise faster, face fewer disruptions, and earn deeper, more reliable customer loyalty.

The Future Is Less Data and More Discipline

India is entering an accountability-heavy marketing era defined by fewer identifiers, stricter consent norms and higher expectations of corporate responsibility. The entire ecosystem of D2C brands, enterprise advertisers, martech companies and platforms must rebuild their growth machines on new foundations.

The consensus is clear that success will depend on first-party ecosystems, high-quality creative, contextual intelligence, and AI models that work without violating consent boundaries. Brands that cling to the older, signal-heavy performance habit will struggle. Those that lean into trust, governance and data ethics will gain long-term stability and a competitive edge.

The DPDP Act may have started as a regulatory requirement, but it is rapidly becoming the defining strategic pivot for India’s digital economy. In the long run, the companies that treat compliance as a catalyst, not an obstacle, will shape the next chapter of Indian marketing.
