Direct Mail Tactics + Results

“It’s a renaissance for physical mail.” —Emily Roberts, VP of Growth Marketing @ Roswell NYC

Winning Back Unsubscribed One-Time Buyers over the Holidays (Medik8): 11.7x ROAS

The Tactic: A three-in-one tactic.

  • Targeting customers unsubscribed from email
  • Targeting customers who had only purchased once
  • Using holiday offers throughout the year to reactivate those one-time buyers

Because direct mail can reach 95%+ of past buyers, a high-ROI use case is sending unengaged or unsubscribed customers your best offers and promotions leading into holidays. In this case, Medik8 was targeting one-time buyers—we routinely see brands drive ever-sought-after second purchases by sending “unreachable” customers holiday offers.

Medik8 uses this tactic throughout the year, on multiple holidays. Check out a couple examples below.

The 4x6 Postcards:

Memorial Day:

Postcard promotion for Medik8 skincare with a pink background and product images including moisturizer, serum, and peptides bottle. Headline: “Memorial Day Sale – 25% OFF, May 20–27, 2025.” QR code and text direct to medik8.us with note “Save 25% on your favorite formulas. No code needed.”

Labor Day:

Winning Back Unsubscribed One-Time Buyers (Medik8 Part 2): 6x ROAS

The Tactic: We just wanted to show another example of direct mail working on unsubscribed one-time buyers. Medik8 created a promotion for “Friends & Family,” but ultimately, the result was the same: reaching the unreachables and driving second purchases.

The 4x6 Postcard:

Promotional postcard for Medik8 skincare. Purple background with images of Medik8 products including a serum, cream, and dropper bottle. Large headline reads “Friends & Family – February 17–23, 2025. 25% OFF, No Code Needed.” Text at bottom: “Save 25% on your favorite formulas. Shop now at medik8.us.” A QR code directs to the online store.

Converting Non-Buyers Subscribed to Email with MailMatchTM (Hyperlite Mountain Gear): 5x+ ROAS

The Tactic: MailMatchTM allows brands to send direct mail to email list subscribers who haven’t purchased yet (no address, no problem—MailMatch can find physical addresses). With MailMatch, Hyperlite pushes their Meta and digital prospecting dollars further by nudging those warm leads to their first purchases.

The 4x6 Postcard:

Postcard advertisement for Hyperlite Mountain Gear. Features three photos of hikers in rugged outdoor settings: snowy landscape, rocky mountain climb, and glacier terrain. Bold headline reads “15% OFF + Daily Deals – Gear Up, Save Big.” Footer states: “Our biggest deals of the year are waiting. Only at hyperlitemountaingear.com.”

Q5 Winback Campaigns (Hallelujah Diet): 12.6x ROAS

The Tactic: Sending “New Year, New You” postcards to win back customers in Q5, an all-important time for health, supplements, and some food/bev brands. This campaign also targeted one-time buyers, bringing them back for more—and helping them achieve their health goals.

The 4x6 Postcard:

Postcard for Hallelujah Diet featuring a smiling woman sitting on a kitchen counter holding a mug, with a salad bowl in the background. Headline: “Enjoy 20% Off – New Year, Healthier You!” Text describes 20% off next purchase and promotes healthier living. QR code and promo code “HDIET20” included, with website myHDiet.com.

The Classic VIP Winback (Hat Heaven): 8x–10x ROAS

The Tactic: If it ain’t broke, don’t fix it. VIP winbacks with postcards work across the board for ecommerce brands, and Hat Heaven has won back many of their biggest spenders (who ordered at least three times), including segments who last purchased between 90–180 days ago and 180–365 days ago.
