A High-Value Audience.
A Crowded Inbox.
A boutique financial planning firm runs monthly dinner presentations to attract qualified prospects for trust and estate planning services. Their primary acquisition channel: targeted direct mail to 30,000 households per month.
The Client
This financial planning firm specializes in trust structures, estate planning, and intergenerational wealth transfer. Their dinner presentations convert high-net-worth prospects into long-term planning clients.
The Challenge
Direct mail response rates in financial services typically hover below 0.2%. With 30,000 mailers per campaign, the firm needed to break through attention scarcity and increase dinner RSVPs without scaling print budget.
The Solution
Boostt AI and agency partner Pixa layered addressable digital advertising on top of the existing direct mail audience. Using household-level audience matching, digital ads reached the same households receiving physical mail, creating a multi-touch priming effect.
The Campaign
A curated dinner presentation on trusts and estate planning served as the campaign landing experience. Digital ads ran January to February 2026 alongside existing 30K-piece direct mail drops.
Apples-to-Apples
Seasonal Comparison
To isolate the impact of addressable advertising, we compared the same two months (January and February) across consecutive years, controlling for seasonal behavior patterns in financial services.
Jan to Feb 2025
Direct mail only. 30,000 household audience per month. No digital ad support. Establishes baseline performance benchmark.
Jan to Feb 2026
Direct mail plus addressable digital ads. Same 30,000 household audience receiving matching digital ad exposure across display channels.
Seasonal Control
Jan to Feb is a consistent period for financial services outreach, post-holiday, pre-tax season. Matching months eliminates seasonal noise and attributes the performance delta to the ad layer.
The Priming Effect
Addressable ads reach the same physical household before the mailer lands. Repeated brand exposure lowers response friction, the recipient has already seen the message digitally, making the mail piece feel familiar and trusted.

Why Addressable Ads
Move the Needle
The Priming Effect in Practice
The core mechanism at work is cognitive priming, a well-documented behavioral phenomenon where prior exposure to a brand increases the likelihood of a positive response to subsequent touchpoints. When a homeowner sees a digital ad for a trusts and estate planning dinner event, then receives a physical mail piece days later, the mail doesn't arrive as a cold introduction. It arrives as a familiar message from a brand they've already encountered.
This is especially powerful in financial services, where trust and familiarity are critical conversion drivers. The addressable ad layer essentially converts a cold outreach into a warm one, without requiring the recipient to have taken any prior action.
The January Effect
January 2026 produced the most dramatic lift: 77 responses vs. 40 in January 2025, a near-doubling despite the ad campaign still being in its ramp-up phase ($520 spend, 6,984 households reached). This suggests the priming effect doesn't require massive ad frequency to generate response lift. Even modest reach, applied to the same household list, meaningfully improved mail response rates.
February Acceleration
February 2026 showed not just continued DM improvement (44 vs. 32 responses), but a dramatic acceleration in the digital channel, CTR grew from 1.5% to 5.3% as audience targeting refined and full budget deployed. This trajectory suggests the channel combination becomes more efficient over time, with digital and physical signals reinforcing each other.
Budget Efficiency
The incremental investment to unlock this lift was modest: addressable ads added roughly 6.7% on top of the existing direct mail budget. That incremental spend drove a 65 to 93% improvement in response rates, a remarkably favorable efficiency ratio for a channel addition.

Incremental Efficiency
The Formula for Modern Direct Mail
Adding a roughly 6% layer of addressable digital ads to an existing direct mail program produced a 92.5% average lift in response rates, turning a proven channel into a high-performance acquisition engine.
This campaign demonstrates a reproducible, measurable playbook for financial services marketers: addressable advertising is not a replacement for direct mail. It is the multiplier that unlocks its full potential.
By matching digital audiences to the same physical households receiving mail, Boostt AI and Pixa created coordinated multi-touch sequences that prime recipients before the mailer lands. The result is a warmer, more familiar audience that is significantly more likely to respond.
As the 2026 campaign data matures and additional months are added, the combined channel signal will continue to strengthen, creating compounding returns on the addressable ad investment.
