Your Commerce Media Network [CMN] is competing for a shrinking slice of a massive pie.

84% of US commerce media spend flows to Amazon and Walmart. The rest of the market — you included — is fighting for what’s left. And if your inventory looks like everyone else’s (sponsored search, onsite display, some offsite digital), brands have little reason to shift budget your way.

The solution isn’t doing digital better. It’s doing something digital can’t.

Direct mail is the channel brands are asking for — and almost no CMN delivers it.

US commerce media spend is projected to hit $69 billion in 2026. Off-site retail media jumped 42% in 2025 alone, and it’s expected to grow 2x faster than on-site through 2026. Brands are actively looking for new ways to activate your first-party data beyond screens. Direct mail is that way.

Why brands want direct mail more than you probably realize

Brands have maxed out digital impressions. Inboxes are full. Feeds are noisy. They need channels that break through — and direct mail is one of the most proven response channels in marketing.

It gets remembered.

60% of recipients find direct mail more memorable than digital ads. It stays in homes, gets picked up again, and creates brand recall that actually translates to purchases.

It reaches buyers when they’re ready.

56% of consumers use direct mail to plan weekly shopping. That’s not reach — that’s reach at exactly the right moment.

Direct mail outperforms email by up to 75x. That’s not a rounding error. That’s a different category of performance.

It’s measurable in the way brands actually care about.

With address-level matchback attribution, you can tie every mail piece to a purchase. No QR codes. No gimmicks. Clean, verifiable incrementality — the KPI that keeps budgets flowing quarter after quarter.

It multiplies everything else you’re already running.

Campaigns combining direct mail with digital see response rates jump 63%, website visits increase 68%, and leads rise 53%. Direct mail doesn’t compete with your digital inventory. It makes it perform better.

Your CMN data is a gold mine. Direct mail is how you cash it in.

You already have what brands are desperate to access: purchase history, category preferences, loyalty behavior, spend levels. The problem is that most CMNs can only offer that data through digital slots that look identical to Amazon’s.

How CMN Brand Partners Win with Direct Mail

Postie powers a set of proven activation strategies designed around the goals brands bring to your network. Whether they’re trying to grow share, launch a product, or build long-term loyalty — there’s a direct mail play that moves the needle.

Convert First-Time Buyers & Boost Sales Lift

Goal: Increase sales velocity / attract new buyers

Your first-party purchase data tells you exactly who hasn’t tried a brand yet — but looks just like their best customers. Brands can activate those lookalike segments through Postie’s privacy-safe platform, reaching high-potential new buyers with personalized direct mail at the moment they’re most likely to convert. You keep the data. They get the reach. Sales velocity goes up for both of you.

Drive iROAS with Persistent In-Home Media

Goal: Win the season / grow market share

Brands competing for seasonal dominance need more than a single impression. Direct mail campaigns running through your network create a physical presence in the home — one that gets seen multiple times over days or weeks, not milliseconds. With address-level matchback attribution, every piece ties back to a real purchase, giving brands the iROAS proof they need to keep committing budget to your network season after season.

Ensure Market Penetration & Sell-Through Velocity

Goal: Launch new items / accelerate discoverability

New product launches live or die by early velocity. Brands that activate direct mail through your CMN can reach targeted households — category buyers, competitor switchers, high-LTV loyalists — within days of launch. Postie’s Print Cloud moves campaigns from approval to in-home in as little as 3–5 days, so brands hit market at full speed, not after the window closes.

Ensure Market Penetration & Sell-Through Velocity

Goal: Launch new items / accelerate discoverability (extended)

For products that need sustained momentum beyond launch week, Postie enables sequenced mail cadences that mirror the retargeting logic brands run on Google and Meta — but with the staying power of something physical. One abandoned cart or missed purchase becomes a multi-touch sequence, each piece arriving at the right interval to re-engage and convert.

Reach 99.99% of Addressable Households

Goal: Trust transference / increase brand awareness

Digital reach has a ceiling. Walled gardens, cookie deprecation, ad fatigue — brands know the limits. Direct mail through your CMN reaches any household in the country, with no algorithm standing between the message and the mailbox. For brands that want to build awareness and transfer trust from your network to their product, this is the channel that completes the picture — and it’s one Amazon and Walmart can’t offer.

Why Postie is the only platform built for CMN direct mail

Direct mail isn’t new. But the ability to run it inside a Commerce Media Network — with the speed, targeting, attribution, and data privacy that brands expect — is. And right now, Postie is the only platform that does it.

01 — You’re live in days, not months.

Postie’s automated workflow handles data onboarding, creative versioning, and printer routing. Mailers hit households in as little as 3–5 days. Your CMN can move at the pace brands expect — not the pace traditional direct mail used to require.

02 — Your data never leaves your ecosystem.

Postie activates your first-party audiences through a privacy-safe, closed-loop system. Brands reach competitor switchers, lapsed buyers, high-LTV customers — without ever accessing a single raw record. You stay in control. Brands get the reach. Everyone wins.

03 — You can scale from 100K to 10M pieces without adding headcount.

Postie’s Print Cloud connects to a nationwide network of vetted printers — optimized for speed, quality, and geographic precision. No vendor juggling. No operational lift. Just scale.

04 — You prove results in the language CFOs and brands actually speak.

Every campaign includes address-level matchback attribution that ties purchases directly to mail exposure. Not impressions. Not clicks. Sales. The incrementality proof that keeps brands renewing and increasing spend through your network.

Make your CMN the one brands talk about.

Brands are expanding commerce media budgets and getting more selective about where those dollars go. They want networks that offer reach, performance, and proof. Networks that go beyond banners and sponsored search. Networks that can do something Amazon and Walmart can’t.

Direct mail is that thing. Postie makes it possible — fast, measurable, data-safe, and built for the scale your CMN demands.

Add direct mail to your CMN in weeks, not quarters.
