Shared Mailers

Use our integration with PostPilot, split direct mail costs with complementary brands, and put multiple relevant offers into one high-impact mailer.

What is a Shared Mailers collab?

A shared mailer is one direct mail piece carrying offers from several complementary brands, with the print and postage split between them. Each brand pays a fraction of a solo mailer while the recipient gets a curated set of relevant offers, which tends to hold attention longer than a single brand postcard.

What Makes Shared Mailers Work?

The mailer should feel curated around one customer need, not like unrelated ads bundled together.

One audience thesis

Agree on the household, lifestyle, or purchase signal that makes every brand in the mailer relevant.

Distinct partner offers

Give each brand enough space for a simple benefit, memorable code, QR code, and landing page.

Shared economics

Define how partners split list costs, creative, print, postage, and reporting before production starts.

Your 4-Step Shared Mailer Plan

Use this plan to keep the mailer focused, trackable, and fair for every partner.
1

Choose the theme

Anchor the mailer around a moment like new movers, first-time parents, seasonal gifting, wellness routines, or pantry restocks.
2

Build the partner set

Invite non-competing brands with similar customer value, compatible creative standards, and offers that can sit together.
3

Design the shared piece

Use a postcard, folded self-mailer, catalog-style card, or envelope pack with one clear section per brand. Our integrated partner, PostPilot.com can handle the mailer design for you.
4

Mail and measure

Use a service like PostPilot.com to coordinate audience selection, send direct mail, and compare results from one shared campaign.

Shared Mailer Plays to Try

Choose the format based on audience quality, budget, and offer complexity.

Neighborhood Offer Pack

Several brands target a geographic area or new-mover list with one coordinated set of offers.

Best for local or regional reach.

Lifestyle Routine Mailer

A small group of complementary brands presents offers around one routine, such as fitness, pets, cooking, or baby care.

Best for relevance.

Winback Mailer

Partners co-fund a premium mail piece to reactivate high-value customers who have gone quiet digitally.

Best for customer reactivation.

Shared Mailers collab questions

What is a Shared Mailers collab?

A shared mailer is one direct mail piece carrying offers from several complementary brands, with the print and postage split between them. Each brand pays a fraction of a solo mailer while the recipient gets a curated set of relevant offers, which tends to hold attention longer than a single brand postcard.

How do brands split the cost of a shared mailer?

Usually by the share of the piece each brand occupies, or evenly when every brand gets the same panel. Costs to divide are design, print, postage, and list rental if any. Agree who fronts the spend and when the others reimburse, since the printer needs paying before any results exist.

Who receives a shared mailer?

Most often each brand's own customer file, mailed as a reciprocal drop, so every brand introduces the others to buyers it has already earned. You can also mail a rented or modelled prospect list, which costs more and converts less. The reciprocal version is the one to test first.

How do you attribute a shared mailer?

Give every brand its own code and its own URL on the piece, then hold the drop date and the measurement window constant across partners. Direct mail responds over weeks rather than days, so measure for at least 30 days before comparing the mailer to a digital channel.
