Data Quality is the bedrock of
great Omnichannel Marketing

Every year, 27MM people move, 35MM phones disconnect, 4.7MM new businesses form, and one in three emails become obsolete. Left unchecked, your marketing data—and your ROI—will crumble. 

Using premium data resources with advanced tech, Double J transforms your customer and prospect data into a reliable asset by ensuring it is always accurate, complete, and ready for action—across all channels, and always with the highest data privacy & security.

Build the ultimate Data Quality Strategy with these powerful services:

Eliminate budget waste and missed opportunities caused by undeliverable outreach. Cleanse and validate your postal, email, and mobile data to capture lost revenue and ensure every message reaches a high-value prospect.

Postal Hygiene
Stop mailing to dead ends. We use gold-standard USPS processes—DPV (Delivery Point Validation), NCOA (National Change of Address), and PCOA (Proprietary Change of Address)—to verify every location and capture moves, ensuring records inactive for up to 30 years are finally corrected.
Email Hygiene
 The most advanced email hygiene in the industry. Identify and neutralize 22 categories of high-risk threats—from pristine spam traps to disabled hard bounces. We don’t just clean your list; we optimize it. Powered by a real-time data co-op and behavioral insights from leading ESPs, we replace bad data with "ready-to-send" contacts for both B2B and B2C campaigns. As a contributing ESP, we leverage the same intelligence to ensure your emails hit the inbox.
Mobile Hygiene
 Protect your brand from TCPA risks. Our mobile hygiene captures over 50,000 daily deactivations and includes Right Party Contact, ensuring you only reach the intended recipient and never a reassigned number.

Broaden your market reach across every channel with new postal records, email addresses, and mobile phones. Deepen your audience insight with the demographics, psychographics, and firmographics needed for greater relevance.

Consumers
260MM individuals across 150MM households. Thousands of demographics and psychographics. All sourced from top-tier compilers.
Businesses
100MM business contacts across 25MM companies. 50MM professionals at home. Hundreds of firmographics. All sourced from top-tier compilers.
Email Appends
Double J delivers the industry's highest match rate at an unprecedented 95%. But we go further: our data is sourced from a continuously updated co-op, tracking real-time consumer and business behavior across the US. As an active ESP contributor, we use these unique behavioral insights to ensure every appended email is an active, deliverable contact, ready to engage with your campaigns immediately.
Mobile Appends
50% – 85% appends. High quality matches at the individual level. Multiple sources including credit bureau data.

Sync the data silos across all your channels to build a single 360-degree view of all your customers and prospects. Stop chasing database managers across departments. End the era of slow, ad-hoc data jobs and get the answers you need, the moment you need them.

From firmographics to intent-driven psychographics, we provide the clean, actionable data required to connect, through any channel, with virtually every consumer and business in the US.

Customer Segmentation
 Identify and power your ideal customer segments by decoding the four pillars of transaction history: Recency, Frequency, Monetary, and Tenure (RFMT). We enhance these insights to project Customer Lifetime Value (CLV), helping you pivot from basic targeting to a predictive model that captures the most profitable segments of your market.
Digital Listening
 Build audiences based on both real time and recent web behavior. Identify not only prospects that match your ideal customer profile, but also customers that are at risk of churn. Behind our digital listening service is a data co-op made up of continuously-fed updates from leading ISPs that track the behavior of virtually every device in the US. As a contributing ESP, we use this data to deliver superior results for our clients. The web is your hunting ground. Master the chase with Digital Listening from Double J.

We can facilitate connections with excellent, pre-vetted print partners upon request.
Campaign Reporting

Success Stories

Client: Leading retailer of health and nutrition products with $2BB in annual revenue from over 2000 stores and internet sales.
Challenge: Boost membership to its premium customer loyalty program.
Strategy: Customer Acquisition:
  • Build audience through digital listening and conquest marketing.
  • Reach audience through email deployment.
Results: Email campaigns generated 51% cumulative opens and 8% clicks. Loyalty program membership grew 4% that year.
Client: Eyecare retailer with $900MM in annual revenue from over 700 stores.
Challenge: Boost revenues at retail stores with declining sales.
Strategy: Customer Acquisition:
  • Build audience through look-alike marketing.
  • Reach audience with A/B split:
    1. Postal deployment only
    2. Omnichannel deployment (postal + digital ads)
Results: Our omnichannel approach dramatically outperformed the postal-only method by generating an 8% lift in unit sales and a remarkable 600% Return on Marketing Investment (ROMI). The campaign's success stemmed from a carefully timed, three-phase execution:
    Phase 1 (Awareness):     Digital ads were deployed one week before the mail drop to "soften" the audience and build initial awareness.
    Phase 2 (Consideration): The heightened awareness ensured more recipients recognized and opened the colorful mail piece, increasing consideration and reducing the likelihood of it being discarded as junk mail.
    Phase 3 (Conversion): Continued digital ad delivery for a month after the mail drop reinforced the call to action, effectively nudging more recipients to visit the store and buy eyeglasses.
    Client: Manufacturer of high-end consumer appliances with over 20MM US customers and $6BB in annual revenue worldwide.
    Challenge: Reverse the decline in engagement on their customer retention marketing campaigns. Concerned that they were losing many of their high-value, high-acquisition-cost customers to the competition.
    Strategy: Customer Retention:
    • Build great data quality by updating customer email file.
    • Reach customer audience through both email and digital ad deployment.
    Results: After refreshing 35% of their customer email file, which had clearly suffered a significant decline in accuracy over time, we doubled email and digital ad engagement on their retention campaigns.
    Client: Liberal Arts college founded in 1812 with over 4k students.
    Challenge: Boost college enrollment
    Strategy: Customer Acquisition:
    • Build audience of parent emails through look-alike marketing.
    • Reach audience through email deployment.
    Results: Email campaigns generated 54% cumulative opens and 2.5% clicks. Of the students that enrolled later that year, 33% had received parent emails.
