Connected TV (CTV) has become one of the fastest-growing advertising channels, giving brands the opportunity to reach engaged audiences on the biggest screen in the house. As advertisers invest more in streaming environments, the conversation around identity and targeting is becoming increasingly important.
For years, email-based identifiers have been positioned as a solution for audience targeting in a privacy-first world. They promised continuity after the decline of third-party cookies by helping advertisers recognize users across devices and platforms.
But as the CTV ecosystem matures, many advertisers are beginning to ask an important question:
Are email-based IDs really the right solution for Connected TV?
The answer is becoming less straightforward. While identity solutions continue to play a role in digital advertising, many industry experts believe that relying too heavily on email-based IDs may limit the true potential of CTV.
Because Connected TV is a shared household experience, relying on a single email-based ID can limit targeting accuracy and campaign performance.
CTV Is Different by Design
One of the biggest misconceptions is treating CTV like desktop or mobile advertising.
Unlike personal devices, televisions are shared by households. A single smart TV may be used by multiple family members throughout the day. Parents, children, roommates, and guests all consume different content with different interests.
An email address may identify the account holder — but it does not necessarily identify who is watching the screen at any given moment.
This creates a challenge for advertisers.
When targeting relies exclusively on an email-based identifier, campaigns may reach the wrong person, reducing both relevance and campaign efficiency.
CTV requires a broader understanding of audience behavior that goes beyond individual identity.
The Industry Is Rethinking Identity
Recent discussions across the advertising industry suggest that email-based IDs are not a universal solution for Connected TV.
Critics argue that these identifiers were originally designed for authenticated digital environments, not shared household devices.
Streaming platforms also differ significantly in how users log in, create profiles, and share accounts. Some services require authentication, while others allow guest viewing or multiple user profiles.
As a result, identity signals can become fragmented and inconsistent across platforms.
For advertisers, this means one important thing:
Identity alone cannot guarantee accurate targeting.
Instead, successful CTV campaigns increasingly rely on multiple signals working together.
Modern CTV advertising combines AI, contextual signals, first-party data, and supply quality to deliver smarter targeting than identity alone.
Context Is Becoming More Valuable
Rather than depending on a single identifier, advertisers are shifting toward contextual intelligence and audience modeling.
In Connected TV, context often provides stronger indicators than individual identity.
Questions like these are becoming more valuable:
What content is being watched?
What genre is attracting the audience?
What time of day is the viewing session?
Which device is being used?
What household characteristics are available?
When combined with privacy-safe data and machine learning, these signals create highly relevant advertising opportunities without depending exclusively on email addresses.
This approach not only improves targeting but also aligns with growing privacy expectations from both regulators and consumers.
Privacy Is Driving New Strategies
Privacy regulations continue to reshape digital advertising worldwide.
Consumers increasingly expect transparency around how their information is collected and used. At the same time, platforms are reducing access to persistent identifiers and strengthening their own privacy controls.
This makes flexibility essential.
Advertisers that rely on a single identity solution may find themselves with fewer opportunities as the ecosystem evolves.
Instead, modern CTV strategies combine:
Contextual signals
Household-level insights
AI-powered audience modeling
First-party data where available
Real-time optimization
The result is a more resilient approach that adapts to changing technology without sacrificing campaign performance.
Performance Still Comes First
At the end of the day, advertisers are not buying identifiers.
They are buying outcomes.
Whether the goal is brand awareness, completed video views, website visits, or incremental reach, success depends on delivering relevant messages to engaged audiences.
That requires more than identity.
It requires high-quality inventory, intelligent optimization, and continuous campaign analysis.
Connected TV offers one of the most premium advertising environments available today. Viewers are highly engaged, ads are highly viewable, and brands benefit from the immersive experience of the television screen.
The challenge is making sure campaigns reach audiences in the smartest possible way.
A Smarter Approach to CTV Targeting
At Screencore, we believe effective CTV advertising is built on multiple layers of intelligence — not a single identifier.
Our platform combines premium Connected TV inventory with advanced audience strategies, contextual insights, and real-time optimization to help advertisers reach the right viewers while respecting user privacy.
Instead of relying solely on email-based IDs, we focus on delivering campaigns that balance precision, scale, and measurable performance.
Because the future of CTV isn't about choosing one targeting method over another.
It's about using the right combination of signals to make every impression more valuable.
As identity signals become less reliable, AI-powered contextual intelligence and real-time optimization provide a more resilient approach to CTV advertising.
The Future of CTV Is Flexible
Identity will remain an important part of digital advertising.
But Connected TV requires a more nuanced approach.
As advertisers demand better accuracy, greater transparency, and privacy-first solutions, the industry is moving beyond one-size-fits-all targeting.
The brands that succeed will be those willing to embrace flexible strategies that combine identity, context, technology, and premium inventory.
Because in CTV, understanding the viewing experience is often more valuable than simply knowing who logged in.
