Automated direct mail for any use case

Customer loyalty and retention

Strengthen the relationship with your best customers through timely, personalized physical mail. Trigger recurring campaigns (birthdays, replenishment, milestones) from your CRM and make each letter count with QR codes to exclusive offers and response tracking. End-to-end automation — just like email.

Re-engagement of inactive customers

Win back dormant accounts with tangible messages that break through inbox indifference. Segment by time since last purchase, value or category, send a relevant letter and measure impact with unique URLs/QRs. Combine it with a remarketing audience to close the loop frictionlessly.

Drive traffic to physical stores

Turn digital intent into real visits. Launch geo-targeted campaigns with redeemable in-store coupons, maps/QR codes and creatives that invite trial. Integrate your POS to confirm redemptions and optimize by neighborhood, hour and average order — without touching a spreadsheet.

Promote events or launches

Give your key dates premium reach with personalized postal invitations. Sync the campaign with your marketing calendar, add RSVP via QR and reinforce with a digital sequence. From design to delivery, fully automated to arrive on time and with impact.

FAQs

How long does it take for a direct mail campaign letter to arrive?
For domestic shipments within Spain, the usual timeframe is 2 to 5 business days, counting from when your campaign goes into production and printing. Total time depends on the volume and format (postcard, letter in envelope, catalog), the province and postal code (rural areas may take 1 extra day) and the calendar (Black Friday or Christmas add 24–48h). For international shipments within the EU, expect 3–10 business days.
Can I measure the real ROI of direct mail for my ecommerce?
Yes. We measure direct mail ROI with 1:1 traceability and cohort analysis: unique coupons per recipient or segment, unique QR/URLs with UTM (direct attribution to the "direct-mail" channel), cohort comparison vs. a control group ("matchback"), optional holdout/A-B testing to isolate incremental lift, and a recommended 14–30 day attribution window.
Do I need a designer to create the letters or can I use templates?
You do not need a designer. You can use templates optimized for abandoned cart, win-back and retention (editable text and images), or upload your own creative designed in Canva, Illustrator or Figma.
Is there a minimum volume to launch a direct mail campaign?
We work from small batches to mass mailings. You can test with a controlled sample (high-LTV segment or dormant VIPs), scale to the full audience if the lift and ROI meet your goal, and re-send to those who didn't convert after the first letter (optimized second wave).
