DTC Brands: Your Klaviyo List is Hiding a Fortune

You’ve built an impressive email list in Klaviyo. It should be your golden ticket to sustainable growth.

But there’s a problem: You can only reach 10-20% of these customers through email.

The rest? They’re ghosts. Unengaged. Unsubscribed. Lost in crowded inboxes or spam folders.

The Hidden Revenue Crisis

Every DTC marketer feels this pain. You’ve spent years in the trenches:

  • Fighting for inbox attention against dozens of other brands.
  • Watching your open rates steadily decline.
  • Seeing your “unengaged” segment grow larger by the month.
  • Struggling to re-engage customers who once loved your brand

It’s happening to everyone.

But knowing that doesn’t make it any less frustrating when you’re leaving money on the table.

Unlock the 80% You Can’t Reach

What if you could tap into that unreachable 80% of your list?

Direct mail cuts through the digital noise like nothing else.

While your emails compete with hundreds of others, your postcard sits on their kitchen counter demanding attention.

The customers who unsubscribed from your emails?

They still check their physical mailbox every day.

Calculate Your Hidden Revenue Potential

We’ve built a simple calculator to show exactly how much revenue you’re missing by relying only on email.

Shocking, isn’t it?

That’s real money left untapped in your Klaviyo account.

We can help.

The Klaviyo Gold Mining Program

Our design team will create your mailers, and our CS/Analytics teams will plan your campaigns (think the Navy SEALs, but for direct mail) to recover lost revenue from your “dark contacts” on Klaviyo.

Usage isn’t included, but you get our lowest per-mailer rate.

Program Details

  • Our team will “echo” your top performing Klaviyo campaigns into PostPilot to plug your funnel and reach way more of your list.
  • SiteMatch Pixel: Start building a retargeting audience of anonymous site visitors—use is optional, but you’ll have it ready to go.
  • Deeper Winbacks: We’ll use your time between orders data to time anti-churn and anti-defection mailers to customers who have been inactive for longer.

Plus, you’ll get:

✅ Done-for-you campaign design, setup, and optimization services

✅ 4 months of our Pro plan for a one-time payment of $1499 (a savings of over $500).

10% of your total launch value matched in postcards: E.g., send 30,000 postcards, get 3k free.

This is a program we’re only offering until the end of March and is exclusive to new PostPilot customers.
