India’s marketing technology ecosystem has grown on a simple assumption: more data leads to better marketing. Over the last decade, brands have built systems to capture signals from websites, apps, loyalty programmes, commerce platforms, and digital campaigns, then combine those signals into customer profiles and targeted journeys.
The Digital Personal Data Protection Act, 2023 changes that assumption.
It does not remove data from marketing, but it changes how data can be collected, stored, and used. The impact is not limited to compliance teams. It reaches into how marketing stacks are designed, how campaigns are executed, and how customer relationships are managed.
By late 2025, the law moved from high-level policy to operational reality. The notification of the DPDP Rules introduced phased timelines, with some obligations taking effect immediately and others scheduled over the next 12 to 18 months. This timeline is important because it gives businesses a limited window to redesign systems that were not built with strict consent and retention controls in mind.
For martech leaders, this is less about interpretation and more about execution. The challenge is not understanding the law. It is reworking the infrastructure that powers modern marketing.
The scale of what is at stake becomes clearer when placed alongside India’s digital growth. Advertising spends in FY2025 crossed ₹1.11 lakh crore, with digital contributing ₹49,000 crore and projected to reach ₹56,400 crore in FY2026. Digital now accounts for nearly half of all advertising. Mobile alone represents close to 78 percent of that spend, while India’s internet base has grown to over 800 million users. Connected TV audiences are expected to reach 50 million in the same period.
This growth is driven by data. DPDP introduces stricter controls on that data, effectively placing new conditions on how marketing operates.
The numbers behind the shift
A few recent datapoints explain why DPDP will reshape martech in 2026:
-
India’s digital ad spend is projected to reach ₹56,400 crore in FY2026, increasing reliance on data-driven marketing
-
The DPDP framework allows penalties of up to ₹250 crore for failure to maintain reasonable security safeguards
-
Large platforms may be required to erase inactive user data after defined time periods such as three years
-
Nearly 75 percent of businesses report at least 10 percent of their marketing data is inaccurate or outdated
-
Around 80 percent of organisations have not yet fully implemented DPDP-ready governance frameworks
Taken together, these numbers highlight two realities. First, marketing is becoming more dependent on data. Second, that data is now regulated more tightly than before.
The result is a structural change in martech.
Consent is moving from banner to backbone
One of the most immediate changes under DPDP is how consent is handled. Historically, consent has often been treated as a surface-level requirement. A banner appears, users click accept, and data collection begins. DPDP makes that approach difficult to sustain. The law requires consent to be clear, informed, and purpose-specific. It also requires that users be able to withdraw consent as easily as they give it. This shifts consent from a one-time interaction to an ongoing system.
For martech teams, this means consent needs to be tracked across multiple systems, not just captured at entry points. A user’s consent state must be reflected in CRM platforms, analytics tools, campaign systems, and third-party integrations.
It also introduces complexity in communication. Consent notices must be available in multiple languages and clearly explain how data will be used. In a country as linguistically diverse as India, this becomes a design and operational challenge.
A senior privacy consultant working with large brands described the shift as follows: “Consent is no longer a checkbox. It is becoming part of the product experience.”
This has direct implications for martech architecture. Customer data platforms and consent management tools must now link consent to specific purposes and ensure that data usage aligns with those purposes across all systems.
Data retention is no longer indefinite
Another major shift under DPDP is the treatment of data retention. In many organisations, data has historically been stored indefinitely. The assumption was that more data would improve targeting, analytics, and personalisation over time. DPDP introduces limits to that approach. Data must be retained only as long as necessary for a defined purpose. In certain cases, organisations may be required to delete user data after periods of inactivity.
For martech teams, this changes how customer profiles are built and maintained. First, it requires a clear understanding of where data is stored. Many organisations operate with fragmented systems, where customer data exists across multiple platforms without a unified inventory.
Second, it requires the ability to delete data across all systems when required. This is more complex than it sounds. Deleting data from a CRM does not automatically remove it from analytics tools, ad platforms, or backup systems. Third, it changes how segmentation works. If data cannot be stored indefinitely, marketers need to rely more on recent behaviour and real-time signals rather than long historical profiles.
This shift moves martech toward more dynamic and context-driven strategies.
Children’s data introduces new targeting limits
DPDP also places restrictions on how children’s data can be used. The law defines a child as under 18 and limits targeted advertising and behavioural tracking in such cases.
For businesses, this creates new challenges in audience segmentation. Many platforms and services have mixed user bases where age is not always explicitly verified. Ensuring that campaigns do not target children unintentionally requires stronger safeguards.
This is particularly relevant for sectors such as gaming, education, and youth-focused consumer products, but the impact extends to any business using broad digital targeting.
It also highlights a broader trend. Targeting strategies based on behavioural tracking may face increasing scrutiny, pushing marketers toward more privacy-safe approaches.
Security and vendor governance are becoming central
DPDP places significant emphasis on data security. The possibility of penalties reaching ₹250 crore for certain failures highlights the seriousness of compliance.
For marketing teams, this shifts how technology decisions are made.
Martech stacks often involve multiple vendors, each handling different parts of the customer journey. Under DPDP, businesses are responsible not only for their own data practices but also for how their vendors handle data.
This introduces a new level of scrutiny in vendor selection. Features and integrations are no longer the only criteria. Security controls, data handling practices, and contractual obligations become equally important.
A technology advisor working with enterprise clients noted, “The conversation is shifting from what a tool can do to how it handles data.”
The financial risk is also significant. Reports indicate that the average cost of a data breach in India reached over ₹20 crore in recent years, even before regulatory penalties are considered. With DPDP in place, the cost of non-compliance increases further.
This is likely to reduce vendor sprawl. Organisations may consolidate tools and prioritise platforms that meet compliance requirements more effectively.
Data localisation and cloud choices are under review
Another area of impact is data storage and transfer. While DPDP does not completely restrict cross-border data flows, it allows for conditions and potential restrictions. This creates uncertainty for businesses that rely on global cloud infrastructure.
Martech platforms often store and process data across multiple regions. Ensuring compliance may require changes in data hosting strategies, including the use of local data centres or region-specific processing.
This could increase costs, particularly for organisations with complex global setups. It may also influence vendor selection, favouring providers that offer localised infrastructure and transparent data practices.
The readiness gap is driving a martech reset
One of the clearest signals of DPDP’s impact is the gap between awareness and readiness.
Recent industry surveys suggest that a large proportion of organisations have not yet fully implemented DPDP-related processes. Many are still in the early stages of understanding requirements and mapping data flows.
This gap is significant because martech systems are not easy to modify quickly. Retrofitting compliance into existing systems requires time, investment, and coordination across teams.
As a result, DPDP is likely to trigger a re-evaluation of martech stacks.
Rather than incremental changes, many organisations may opt for broader restructuring. This could involve replacing tools, redesigning workflows, and building new governance frameworks.
What changes in everyday marketing operations
The impact of DPDP becomes clearer when viewed through daily marketing activities.
Campaign planning will include privacy considerations from the start. Teams will need to define what data is used, how consent is obtained, and how compliance is ensured.
Customer journeys will include consent management and withdrawal processes as standard elements.
CRM strategies will incorporate data retention and deletion rules, ensuring that customer data is managed responsibly throughout its lifecycle.
Vendor evaluations will extend beyond functionality to include security, compliance, and audit capabilities.
Measurement approaches will evolve to rely more on aggregated data and privacy-safe methods, reducing dependence on individual-level tracking.
These changes do not eliminate marketing effectiveness. They redefine how effectiveness is achieved.
A shift from data abundance to data discipline
The broader impact of DPDP is a shift in mindset. For years, marketing has operated on the principle of data abundance. More data meant better insights and better targeting. DPDP introduces the concept of data discipline. Data must be collected with purpose, used responsibly, and managed carefully.
This does not reduce the importance of data. It increases the importance of how data is handled. A martech leader at a large consumer brand summed it up simply: “We are not losing data. We are losing the ability to use it casually.”
What comes next for martech
The reshaping of martech under DPDP will not happen overnight. It will unfold over the next one to two years as businesses adapt to regulatory requirements and operational challenges.
Some changes will be immediate, particularly around consent and security. Others, such as data retention and system integration, will take longer. What is clear is that DPDP is not a temporary adjustment. It is a structural shift that will influence how marketing technology evolves in India. The martech stacks that succeed in this environment are likely to share certain characteristics. They will have clear data inventories, purpose-linked consent systems, strong governance frameworks, and the ability to adapt quickly to regulatory changes.
For businesses, the challenge is not only compliance. It is maintaining marketing effectiveness within new constraints. DPDP does not end data-driven marketing. It changes the rules under which it operates. And in doing so, it forces martech to move from a model built on access to one built on accountability.
