Experian received top ranks for hashed emails (HEMs) and demographic data from Truthset Data Collective

Advertisers, technology partners, and agencies are all chasing accurate data to power their marketing strategies. Turns out, not all data is created equal and unless you’re working with the right partner, high-quality data can be hard to find. That’s because accuracy can vary widely across the industry and the partner you choose is important. A recent study conducted by data validation company Truthset showed that 51% of the data used for ad targeting and audience measurement is wrong, with average accuracy rates ranging between 32%-69% across data providers.
The data quality challenge
The lack of high-quality data poses multiple challenges in the advertising world:
- Wasted ad spend: without accurate data at the start, marketers can’t reach the right audiences, resulting in wasted impressions.
- Privacy and compliance: in an increasingly privacy-centric world, advertisers need to be especially mindful of accurate targeting to avoid putting their brand reputation at risk.
- Poor campaign performance: low-quality data skews metrics and attribution models, making it difficult to measure campaign success and optimize spend.
Low-quality data can come in different forms like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover) or simply the wrong relationship can be made between datasets. Data records can be incomplete or duplicative and data segments could be misclassified or inaccurate. For example, a kids snack food company may think they’re targeting a 35-year old man, who lives in the suburbs with his young family when in fact it’s a 65-year-old woman who moved to the city after her kids went to college. It’s wasted dollars!
Build the data foundation
Data quality needs to be addressed if advertisers and advertising technology partners want to fulfill consumers’ demand for personalized marketing. Per eMarketer, more than 75% of internet users worldwide said they were willing to share their email address, brand interest, and name in exchange for personalized experiences. Without accurate data, marketers won’t be able to provide the level of personalization that consumers desire.
Validation can help advertisers evaluate third party data and help build trust across the ecosystem. Companies like Truthset review and provide an unbiased evaluation of data fidelity and quality on a regular basis.
“As cookies and mobile ad identifiers continue to phase out, consented, durable identifiers (hashed email, postal addresses) are going to serve as the foundation for identity solutions of the future,” said Chip Russo, President at Truthset. “And the only way to ensure you are transacting on the highest quality identity and demography data is to actively validate the data you rely on with a third party.”
Not all data is created equal: Experian leads the way
In Q3 2023 Truthset reviewed Experian’s marketing data – as well as several other large data providers – and found:
- Experian is the #1 data provider in terms of largest volume of high-accuracy hashed e-mails (HEMs) with demographic data
- Experian ranks #1 in accuracy for 15 marketing data attributes, including but not limited to Age, Gender, Home Owner/Renter, Geography, Education, Presence of Children, and Pet Owner
- Experian consistently has the largest number of HEMs with demographic data that are 90% or more likely to be accurate
“As a member of the Truthset Data Collective, Experian received top ranks across a variety of categories for its data,” continued Russo. “The entire digital advertising world runs on data, but focusing on data accuracy is going to drive the next phase of innovation for the industry, enhancing ROI for advertisers, CPMs for publishers, and relevant experiences for consumers.”
As Truthset’s recent study highlights, the data matched between hashed e-mails and postal addresses is crucial, underpinning everything from targeted ads to TV audience measurement. Highly accurate HEMs linked to high-quality demographic data should be the foundation of any marketing plan. Advertisers are able to overcome the complexities of identity resolution by tying online and offline touchpoints together to deliver a consistent message across channels.
Companies are striving to eliminate marketing waste and provide consumers with personalized marketing and the advertising industry can have confidence that Experian’s marketing data has been externally validated as being highly accurate. The accuracy of our data will power smarter marketing initiatives, like insights, targeting, identity, and measurement.
Let’s start a conversation about how we can fully realize the potential of data-driven advertising together.

As part of our ongoing series which focuses on consumer and marketing trends around major holidays throughout the year, we’ve just released the Father’s Day Hot Sheet. Father’s Day gift-related searches Now that Mother’s Day has come and gone, consumers will be shifting their focus to dad. According to Experian Marketing Services’ Hitwise® online intelligence tool, searches for “Father’s Day” typically start to pop up on Mother’s Day. And searches for “Father’s Day gifts” tend to focus on affordable gift ideas that are personalized, unique and often handmade. In fact, two of the top variations of Father’s Day gift-related searches from 2014 were for “DIY” and “homemade” gifts. While many shoppers wanted the “best” gift for dad, others simply wanted something “cheap” or “last minute.” Finding a gift that dad will appreciate means looking for something that is personalized to him. As such, searches for Father’s Day gifts often contain additional information about the dad or, in many cases, grandpa. Examples commonly used in 2014 were “Christian dad,” “new dads,” “outdoorsy dads” as well dads who are wine or BBQ lovers. While many gift searches include information about the intended recipient, others mention details about the gift-giver or their relationship to the father. Among last year’s variations that included such details, nearly a third focused on gifts that were intended to be given by a “daughter.” Genderless references, such as “kids” or “children” were almost as common. Interestingly, fewer than ten percent were for gifts to be given by a “son.” About a fifth of searches included details about the age of the gift-giver (e.g.: “baby,” “toddler” or “first grader”), while others specified that the gift was to be given by the dad’s wife or girlfriend. Go, go, gadget dad! Gadgets and gizmos are always popular gifts for the techie dad. In fact, during the week immediately preceding Father’s Day last year, visits to Electronics and Appliance websites were up a relative eight percent from two weeks prior. Visits subsequently tapered off the following week. An analysis of search terms driving traffic to the Hitwise Electronics and Appliance industry the week ending June 14 versus May 13, 2014 also sheds some light on the specific items that Father’s Day gift-givers were likely to have been seeking out. Two GPS systems (“Magellan GPS” and “Tom Tom”) were among the top terms that grew search share in the weeks leading into Father’s Day last year. Likewise, “GoPro” appeared in two separate fast growing search terms. Gadgets like these and others listed in the adjacent table may be big gifts for the gadget-loving dad again this year. Gone fishin’ Fishing is a timeless family pastime enjoyed by millions of Americans. According to Experian Marketing Services’ Simmons® National Consumer Study, 28 percent of dads and 26 percent of kids ages six to 17 went fishing last year. As such, it’s no surprise that online searches related to fishing spike over Father’s Day weekend. On the Saturday before Father’s Day in 2014, searches including “fishing” were a relative 28 percent higher than they were the Saturday prior and 64 percent higher than they were the following Saturday. To better understand what kids and dads were seeking out for their fishing plans, Experian Marketing Services conducted an analysis comparing variations of “fishing” searches immediately before Father’s Day last year to those performed two weeks prior. It turns out the word “techniques” was almost 8.6 times more likely to appear in fishing-related searches just before Father’s Day than it was two weeks earlier and “tips” was four times more likely to be used. Likewise, “licenses” was used 2.3 times more frequently, which along with the higher use of “techniques” and “tips” is evidence that many would-be fishermen and women are occasional participants at best. The fact that “charter” and “cabins” were used at higher rates however suggests that other children and/or dads had something in mind beyond a lazy (and likely more affordable) afternoon at the local fishing hole. Gift items, too, like “reels,” “gear” and “tackle” were among those most disproportionately used in searches heading into Father’s Day.

Welcome! Who doesn’t like a warm welcome? Whether your customer is walking into your store or just signed up on your website to receive communications from you, she expects a warm reception. It’s important to make that first impression count. A welcome series helps the conversation open up between the customer and your brand. It sets expectations on the types and cadence of content the customer will receive. Welcome emails also garner 86 percent higher open rates than regular promotional mailings – not too shabby! In a recent webinar, Saks Fifth Avenue shared that they are constantly testing new and current programs to optimize the customer experience. As a result, they discovered that switching from batch-sending welcome emails to sending welcome messages in real time increased open, click and redemption rates significantly. Here’s an example of their welcome series: Saks’ results are consistent with Experian Marketing Services’ welcome email findings which indicate that emails triggered in real time receive up to 10 times the transaction rates and revenue per email vs. those that are batched. A welcome series has also been shown to increase retention by educating customers on new ways to use products and services they’ve purchased from your brand. These emails also can remind customers of the benefits they’ll reap from enrolling in your loyalty programs or credit card. … and welcome back Even if a customer has been welcomed and has interacted with your programs, a day may come when the customer goes silent. Reactivation campaigns are an effective way to get them to re-engage. Naturally, it’s important to target your dormant customers in a variety of channels so you can reach them more effectively. Maybe you’re wondering why I jumped from the warmth of a welcome series right into reality of needing a reactivation campaign. The reason? Marketers need to understand where a customer is in their lifecycle and come full circle with customers if they have parted ways. Marketers can pique the interest of a returning customer by telling them what’s new and reintroducing them to their brand. Carnival® Cruise Lines, for example, sends a welcome-back email that features the newest social networks, offers and deals its customers can take advantage of immediately. At the end of the day, customers expect to receive relevant and engaging messages throughout their entire relationship with a brand. Customer life cycle programs deliver just that.

In a previous blog entry, Ordering sushi and a lesson in embracing the contextual marketing mindset, I showcased a fictitious scenario that required complex data point integration to pull off. These kinds of programs can seem overwhelming given the three barriers that many organizations face when embarking on their contextual marketing journey: Marketing sophistication A brand’s own conventional mindset and the programs that support it Actionable data Lack of clean and accurate data that prohibits real-time “on the fly” interactions Technology Disparate systems that are unable to link information across repositories, channels and interactions; inability to automate interactions in real-time Regardless of the barriers, there are ways you can show customers you’re listening and provide contextual messages without “boiling the ocean.” Take, for example, the recent viral blue/black vs white/gold dress debate. As the conversation spread throughout Facebook and Twitter, brands like Dunkin’ Donuts and Tide tweeted these contextual messages: The tweets did not go unnoticed as thousands of followers retweeted, commented and favorited these messages. The contextual elements used in these messages — channel preference and breaking/relevant news — are easily accessible to any brand. While the brands had to act swiftly, executing these messages circumvented the three barriers listed above. On the flip side, addressing the barriers can allow a brand to build more sophisticated, targeted contextual messages, as shown in the below example. Here, Experian Marketing Services and technology partner Movable Ink helped Finish Line deliver this sale announcement that adjusts based on the date and time the customer opens the email. The message remains relevant via a countdown clock during the run of the sale, a “warning” when it’s about to end and an alternative message after the sale ends — all of which ensures that the message is relevant regardless of when it’s opened by its intended recipient. And combining more contextual data points, such as location and stock, Finish Line includes the countdown, a local map to the customer’s nearest location and up-to-the-minute inventory of available sizes. Contextual marketing enables modern enterprises to engage in customer-centric conversations that — like any meaningful relationship — deepen across time and future points of engagement. This is particularly true in an era when consumers are overwhelmed by untargeted and disruptive marketing messages. By contrast, contextual marketing is designed to seamlessly and usefully merge into the customer’s daily activity. Want to know more and how to get started?
