Dealership mail, designed to go out in minutes

NUMBAT is physical mail outreach for car dealerships, and for the salesperson who wants to mail their own customers. Pick who gets it, pick what it says, approve the proof. We are building it so the printing, postage and tracking happen behind that one approval.

The free Audience Prep tool runs in your browser. Your customer file is never uploaded.

A small mail-sorting desk: blank paper cards lift one at a time off a cleaned stack under a pulsing teal tick, ride a raised teal sorter ring, then tip upright and drop into one of three mailbox slots with terracotta, teal and brass caps Drag to spin

Why mail stalls

Mail still lands. Sending it is what hurts.

A postcard in a customer's hand is hard to ignore. The trouble is everything between the idea and the mailbox.

01

The list

Pulling the right customers out of the CRM, cleaning the addresses and getting them into a format a printer will accept is most of the work, and nobody wants to own it.

02

The middle

Design, proofs, print quotes, postage classes and a vendor who needs a purchase order. Every step is a place a campaign quietly stops.

03

The follow-up

A piece goes out and nothing connects it back. Who responded, who walked in, and whether it was worth repeating usually stays a guess.

Start with the list. Clean it in your browser.

The first piece of NUMBAT is live. Drop a customer CSV into Audience Prep and get back a list a printer will accept, plus a report of every row that cannot be mailed yet.

  • Rows with no name, street, city, state or zip are flagged with the reason, line by line.
  • Duplicates are removed when the name, street and 5-digit zip match.
  • States and zips are normalized "Washington" becomes WA, and the leading zero Excel strips from a zip comes back.
  • Nothing is uploaded the whole check runs on your device. You download the clean list and the reject report.

The flow we are building

Four steps, then it is out of your hands

This is the design NUMBAT is being built to. None of these steps is open yet, and nothing here is a service you can buy today.

  1. Choose the audience Planned

    Filter customers you already have: sold in a given window, service only, lease ending, equity position, or a list you upload and clean yourself.

  2. Choose the piece Planned

    Start from a template made for car sales and change the words. Your store, your name, your number, your photo if you want it there.

  3. Approve the proof Planned

    One screen showing exactly what will arrive and what it costs in total. Nothing prints before you press approve.

  4. Watch what comes back Planned

    Each piece carries its own way back, so a reply can be traced to the campaign that caused it rather than to a hunch.

Drawing, not a product screenshot.

For one rep

One salesperson, the reach of a whole store

NUMBAT is designed so one person can run it for their own customers. Not a cut-down version, the same tool a store uses.

If you are willing to invest in yourself, you could put a real, well made piece in front of your own book every month, under your own name. The size of your outreach stops being decided by the size of your employer.

  • Your customers hear from you, not from a blast that happens to include them.
  • The relationship stays with the name on the card.
  • You are not waiting on a marketing calendar or a budget meeting.

Plainly

What NUMBAT is not

Not shipping yet

NUMBAT is in development in the Marsupial family, alongside KANGAROO, WALLABY and POSSUM. This page describes what it is being built to do. When mail can be sent through it, this page will say so.

Not a list vendor

It works from customers you already have a relationship with, or a list you bring. It does not sell you strangers.

Not a response-rate promise

Anyone quoting you a response rate before they have seen your market, your list and your piece is guessing. We will not.
