Common Questions, Answered

Direct mail retargeting (also called postcard retargeting, postal retargeting, retargeted postcards, retargeted direct mail, programmatic mail, or behavioral direct mail) uses website behavior and purchase intent signals to send personalized mail to people after they visit a brand’s website. It allows brands to follow up with physical mail based on real browsing activity.

For more information about direct mail retargeting and how it works, you can view a blog post here.

The NaviStone platform captures first-party behavioral signals from website visitors, models for propensity to convert, matches qualified visitors to postal addresses, and automatically triggers personalized mail. Campaigns run through automated production and delivery workflows.

Traditional direct mail is typically batch-planned and sent to static lists. Direct mail retargeting is triggered by real-time website activity and personalized based on recent engagement.

Although NaviStone wasn’t founded until 2016, its founders invented direct mail retargeting in 2005 by bridging the gap between online and offline behavior. The specific patent was granted on December 31^st, 2019.

Digital retargeting delivers ads through online channels, while direct mail retargeting delivers physical mail based on the same behavioral signals. It helps brands reach audiences who may be unreachable or oversaturated in digital channels.

• Responsible Sourcing: All postcards are printed on Forest Stewardship Council^® (FSC) certified paper, ensuring they originate from responsibly managed forests that provide environmental, social, and economic benefits.

• Waste Reduction: By targeting only high-intent digital browsers, our data-driven approach eliminates waste by ensuring mail pieces are only sent to households likely to engage.

Incrementality is the measure of real additional revenue or conversions generated by a specific action, message, or campaign, which would not have occurred otherwise. It separates organic growth from advertising lift, ensuring that ad spend contributes real impact rather than wasting money on customers who would have bought regardless of whether they were served an ad or not.

Incrementality measures how much additional revenue or conversions occur because of the addition of direct mail that would not have happened otherwise. It isolates the true impact of the channel.

Incrementality is measured using holdout testing, where a portion of the audience is intentionally withheld from receiving mail and compared against the mailed group.

A randomized control group does not receive mail while the test group does. The difference in conversion or revenue between the groups represents incremental impact.

Incrementality testing, cost-per-piece reporting, ROAS, and conversion lift provide measurable and auditable performance metrics aligned with common financial evaluation methods.

Direct mail reporting can include matchback analysis and attribution windows typically ranging from 30–90 days. This allows brands to understand how mail contributes alongside digital channels.

• A matchback analysis is a data-matching process used in direct marketing that attributes offline purchases to specific marketing campaigns by cross-referencing customer sales data with the original mailing list.

The platform uses first-party website behavioral signals and privacy-compliant third-party identity data to recognize visitors and trigger mail.

No. NaviStone models the browsing behavior of website visitors, then uses third-party data partners to connect the visitor ID to a name and address. Browsing data is used solely on behalf of the advertiser for the purpose of scoring their website visitors. Enabled by a patented double-blind technology system, NaviStone ensures that neither the advertiser nor NaviStone ever takes possession of the visitor’s PII (name/address). We match the intent to the mailbox without ever ‘seeing’ the person behind the screen. More information can be found on our dedicated privacy page here.

Data is handled through secure workflows, used only for campaign execution, and processed within a controlled production environment. Address data is not exposed for general marketing use and is not shared, combined, sold, or made available to anyone other than the advertiser.

The platform operates in compliance with GDPR, CCPA, and CPRA and relies on first-party signals and privacy-compliant data partnerships.

Brands typically provide website tracking access, data integrations, and coordination with marketing and analytics teams. Brands are assigned a dedicated account manager, who handles day-to-day execution and provides strategic recommendations.  NaviStone is a low-lift solution for brands, and we pride ourselves on taking work off a marketing team’s plate, not adding more to it.

Onboarding includes:

• Technical setup (placing a Javascript code on the advertiser’s site)

• A modeling window (typically a few weeks to monitor intent and score visitors)

• Campaign planning supported by an operations representative and a dedicated account manager

Campaign performance is continuously analyzed and communicated by a dedicated account manager using incrementality testing, dashboards, and reporting to inform adjustments and strategic recommendations.

Brands with strong web traffic and higher average order values tend to see the strongest performance from behavior-triggered mail programs. Our best results are typically held by eCommerce brands that have:

• An average order value of at least $75

• More than 100,000 monthly unique website visitors

• High-consideration products available for purchase

The highest performing industries are typically:

• Apparel and Accessories

• Beauty

• Travel

• Retail

• Most industries that involve high-consideration purchases (think automotive, luxury goods, etc.)

Brands often measure improvements in:

• Return on Ad Spend (ROAS)

• Incremental Return on Ad Spend (iROAS)

• Response Rate (RR%)

• Conversion Lift

• Re-Engagement of Abandoned Shoppers

Digital channels often hit a point of diminishing returns where increasing spend actually lowers your margins. Direct mail serves as a high-impact alternative that cuts through digital fatigue. While the unit cost is higher, the incremental lift and higher average order values (AOV) typically lead to a more profitable bottom line and a better return on investment.

Beyond the immediate conversion, direct mail offers a "shelf life" that digital ads can’t match. While a digital ad disappears the moment a user scrolls, a physical piece of mail often lives on a kitchen counter or desk for days, serving as a persistent brand reminder. Key ROI drivers include:

• Higher Brand Recall: The tactile nature of mail creates a stronger neural connection, making your brand more memorable during the decision-making process.

• Ad-Block Immunity: Direct mail bypasses digital fatigue, privacy sandboxes, and ad-blockers, reaching 100% of the intended households.

• Household Multiplier: A single mailer is often seen by multiple members of a household, increasing the "organic" reach of a single spend.

• Price Stability: Digital marketing channels are inherently volatile, with KPIs fluctuating alongside real-time bidding and keyword demand. In contrast, direct mail pricing remains highly stable, mitigating budget variance and ensuring more consistent campaign outcomes.

Programs use behavioral triggers, automated production workflows, and daily printing supported by dedicated operations and account teams. Our main differentiators are:

• >50% increase in ROI compared to competitors

• NaviStone leverages first-class mail l to reach shoppers while they are still in the decision-making phase. Unlike standard competitors, whose mailings can take 7 to 10 days to arrive after a website visit. NaviStone prioritizes speed to capture high-intent shoppers before they move on to a competitor.

• First-party data remains yours alone. Competitors contribute your data to an identity graph (and your competition). Our double-blind patented technology assures that no single party possesses both name and address and behavioral data, providing enhanced privacy protection and data security to all involved. Data is never shared, combined, sold, or made available to anyone other than the advertiser.

• NaviStone provides dedicated strategic consultation and white-glove service. Each customer is assigned a client partner and coordinator, ensuring both strategy and execution are seamless and optimized. NaviStone boasts an 8.6% employee retention rate, meaning that our client partners stay consistent and understand how your business changes over time.

• NaviStone’s modeling enables hyper-personalization, with the ability to tailor messaging and content based on products viewed or explored.

• NaviStone returns postal rebates to clients rather than keeping them as profit. More than one million dollars are returned via rebates to clients per year.

As digital spend increases, returns can decline due to saturation. Adding a new channel allows brands to reach audiences in a different environment. Studies show that direct mail also increases brand recall and loyalty, due to the tangibility and longevity of physical media.

Direct mail is typically used alongside digital channels to extend reach and improve overall marketing performance.
