The full playbook: setup, segments, testing, automation, and scaling direct mail for e-commerce
Direct mail is one of the easiest and most profitable channels you can add to your e-commerce brand this year. And most brands aren't doing it yet. Here's exactly how to get started, what to test, and how to scale it.
The platform, where to start:
We recommend Postpilot. There are other options out there, but for every client we run direct mail for, Postpilot is what we use, primarily for UK and US brands. If you're in a different geo, a quick search will surface the best local alternative.
Step 1: Test different segments as campaigns.
Don't automate anything yet. Start by sending one off campaigns to four key segments: win back, cross sell, VIP, and abandoned checkout. One note on abandoned checkout, only test this if you're a high AOV brand. If not, stick to segments where people have already purchased from you.
How much to spend on testing:
Good rule of thumb: take 1% of last month's revenue. If you did a million last month, that's $10K to play with. Divide that budget across your test segments. You'll probably get around 15,000 mailers or more from that spend.
Step 2: Read the results (give it 60 days).
Direct mail isn't like email where you see results the next day. It takes time. After about 60 days, you'll start seeing real data. A realistic example: win back might come back at 4x, cross sell at 3x, VIP at 3.5x, abandoned checkout around 2x. You can also AB test different offers during this phase to find what resonates.
Step 3: Automate what works.
Once you know which segments are profitable, automate them. Your win back, cross sell, and VIP campaigns become flows that trigger daily or weekly, just like your email automations. If a segment underperforms (say abandoned checkout only hit 2x and that doesn't work for your margins), you can either cut it or go deeper, test it only for customers who've already purchased, or only for your highest AOV products.
Step 4: Go advanced.
Once the core automations are running and you're confident in the numbers, you can push into more advanced plays. Mail match lets you target cold traffic, people who visited your site but never gave you an email. Postpilot matches them and sends direct mail. You can also use direct mail for brand building: handwritten letters, catalogues, brand story pieces. These won't bring a direct ROI in 60 days, but they build something deeper. You can also run one off campaigns for product launches, sales events, or re-engagement, targeting people who've stopped opening emails and SMS entirely.
Quick tips on creative:
Look at what headlines, subject lines, and offers are already working in your email and SMS, then use the same messaging for direct mail. Keep your brand name and URL easy to type. Add a QR code (not everyone scans them, but it removes friction for those who do).
The bottom line:
Start simple. Test win back, cross sell, and VIP. Automate what's profitable. Then scale into cold traffic, brand plays, and re-engagement. This channel compounds fast once you know the numbers, and most of your competitors aren't even thinking about it yet.
