What if the customer only entered an email address and never typed a street address?

This is one of Thanks.io's biggest superpowers for Shopify merchants. When an abandoned checkout contains only an email address and no physical street address, Thanks.io automatically matches that email to a verified physical postal address 60% to 70% of the time using our national consumer identity graph. This instantly unlocks 2× to 3× more reachable abandoned cart volume compared to legacy direct mail platforms that force you to discard incomplete shipping forms.

How does Thanks.io know the shopper's physical postal address?

Thanks.io utilizes a two-tier address capture model. If the shopper typed their shipping address on Step 1 of Shopify checkout, Thanks.io ingests and CASS-cleanses that address. If the shopper abandoned after entering only an email address, Thanks.io automatically queries its consumer identity resolution database to append the verified residential postal address 60% to 70% of the time.

Why wait 24 hours before sending physical direct mail?

Most digital abandoned cart emails and SMS messages fire within the first 1 to 4 hours. By setting a 24-hour delay filter on Thanks.io, you avoid spending direct mail budget on shoppers who were already going to convert from a free email. The postcard arrives at hour 48–72 to rescue the remaining 80%+ of lost revenue.

How does the dynamic QR code reload the customer's cart?

Thanks.io dynamically inserts Shopify's cart token into the QR code URL (e.g. `https://yourstore.com/cart/{token}?discount={code}`). When the recipient points their smartphone camera at the physical postcard, the link opens Safari or Chrome with their exact products already in the cart and the discount code automatically applied at checkout.

How much does it cost to send an abandoned cart postcard?

Thanks.io charges a flat $0.64 for a 4×6 full-color postcard and $0.99 for a 6×9 jumbo postcard. This includes high-resolution full-color printing on 12pt cardstock, authentic handwriting fonts, dynamic QR codes, and USPS First-Class postage. If Thanks.io matches an email-only record to a physical address, it's just $0.07 per successful match. There are zero platform retainers, zero monthly subscriptions, and zero minimum order quantities.

How fast do postcards enter the mailstream?

All postcards submitted before 1:00 PM EST are printed, addressed, CASS-cleansed, and transferred to the USPS First-Class mailstream the next business day. Deliveries typically arrive in recipient mailboxes within 2 to 4 business days nationwide.

How does Thanks.io compare to PostPilot?

While PostPilot is tailored for Shopify, it requires monthly software subscription plans ranging from $1,000 to $2,500/month plus per-card printing fees. Thanks.io delivers identical high-resolution print quality, automatic 60%–70% email-to-address matching, dynamic QR attribution, and faster 48-hour turnarounds with $0 monthly fees, letting you test and scale on pure unit economics.

The Retention Dilemma

Digital Retargeting Is Saturated. Physical Mailboxes Are Not.

Email open rates have slumped below 20%, SMS incurs carrier registration red tape and spam complaints, and iOS privacy killed pixel retargeting. Direct mail cuts straight to the customer's kitchen counter.

Why Incomplete Checkouts Stop Being Wasted Leads

In a standard Shopify store, over 60% of shoppers drop off at Step 1 of checkout—entering their email to see shipping costs, but abandoning before typing out their full street address. On competitor platforms, these high-intent shoppers are discarded.

Recovers shoppers who entered an email in Step 1 of checkout but dropped off before typing their street address.

Works with email-only leads from Klaviyo popups, Omnisend forms, and exit-intent newsletter signups.

Every address is automatically CASS-cleansed and USPS DPV-verified before printing for guaranteed deliverability.

Zero wasted spend: cards are only printed and mailed when a high-confidence deliverable physical address is matched.

Setup Guide

Connect Shopify in Under 10 Minutes

No complex apps or developer contracts. Automated direct mail runs seamlessly using native Shopify webhooks with automated address enrichment.

Enable Shopify Abandoned Checkout Webhook

In your Shopify Admin, navigate to Settings > Notifications > Webhooks. Click 'Create Webhook', select Event 'Checkout update' (or 'Checkout creation'), and set format to JSON. This passes all abandoned checkouts, including email-only dropoffs.

Paste Pre-Mapped Thanks.io Inbound Endpoint

Create a dedicated 'Shopify Abandoned Carts' Mailing List in Thanks.io. Copy your unique inbound webhook URL which automatically captures recipient name, email, line items, and cart token. Thanks.io automatically resolves missing addresses 60%–70% of the time.

Configure Dynamic QR Code Cart Reload

Set the QR destination to `https://yourstore.com/cart/{{token}}?discount=RECOVER15`. When scanned, Shopify immediately restores the shopper's items and applies their unique recovery coupon in 1 tap.

Set Delivery Timing & Watch Revenue Recover

Add a 24-hour delay filter so digital email sequences have time to convert first. Any shopper who hasn't converted within 24 hours gets queued for next-day physical print and USPS dispatch.
