PostGrid Alternative for Australian Shopify Brands
PostGrid is print-and-mail infrastructure: a REST API for letters, postcards and cheques, plus an AMAS-certified address-verification API. TouchDrop is a finished postcard-marketing product for Australian Shopify brands. The honest comparison is not better or worse, it is who does the assembly: with PostGrid your team builds the flows; with TouchDrop the flows are the product.

How TouchDrop compares to PostGrid
PostGrid describes itself as built for developers: you integrate its REST API (or wire Zapier recipes and Klaviyo workflows) to create postcards, letters or cheques when events fire. TouchDrop ships the campaign layer PostGrid leaves to you: pre-built win-back, abandoned-cart and post-purchase flows, per-recipient discount codes, QR attribution and holdout guidance, run by a marketer from a dashboard.
| Feature | TouchDrop | PostGrid |
|---|---|---|
| What it is | Shopify-native postcard campaign platform | Print-and-mail REST API + dashboard |
| Built for | Marketing teams at DTC brands | Developers and ops teams |
| Lifecycle campaigns | Pre-built: win-back, abandoned cart, post-purchase | None pre-built; you assemble triggers via API, Zapier or Klaviyo |
| Shopify connection | Native event triggers | REST API, webhooks or Zapier recipes |
| Klaviyo | Yes, segment sync built in | Yes, via workflow integration |
| Revenue attribution | Per-recipient discount code + QR, ROAS dashboard | Print and delivery tracking; response attribution is yours to build |
| Mail formats | Postcards (marketing) | Letters, postcards, cheques, self-mailers |
| Currency | AUD, GST included | USD (per their AU pricing page footnote) |
| Australian fulfilment | Printed and lodged inside Australia | Operations in 8 countries with vendor routing (their wording) |
| Address verification | AU validation + parcel-locker filtering, built into campaigns | Standalone AMAS-certified verification API; free US/CA checkout app |
When PostGrid is the better choice
- Transactional and operational mail at API depth. Invoices, statements, compliance letters and cheques generated programmatically from your own systems are exactly what a print-and-mail API is for.
- Standalone address verification. PostGrid's AMAS-certified address-verification API can be used on its own, and its free Shopify checkout app validates addresses against USPS and Canada Post standards.
- Multi-country sending from one platform. PostGrid cites operations in 8 countries with local postage rates; if you mail the US, Canada, the UK and Australia from one integration, that breadth matters.
- No subscription to start. Its published starter tier is US$0 per month with pay-per-piece rates, per its AU pricing page (which prices in USD per its own footnote).
When TouchDrop is the better choice
- A marketer, not a developer, runs the direct-mail channel: campaigns are configured in a dashboard, not assembled from API calls and Zapier recipes.
- You want the proven lifecycle flows pre-built: win-back, abandoned cart and post-purchase triggers from Shopify and Klaviyo events, with a CSV path for non-Klaviyo stacks.
- Revenue attribution should be built in: every card carries a unique Shopify discount code and QR code, so reactivated sales attribute to the individual recipient, measurable against a holdout.
- You sell to Australian customers: TouchDrop prints and lodges inside Australia and bills in AUD with GST included, with rates published on the pricing guide.
- Australian address hygiene is handled: AU address validation, postcode checks, parcel-locker filtering, suppression lists and frequency caps run automatically on every campaign.
Frequently asked questions
What is PostGrid?
PostGrid is print-and-mail infrastructure: a REST API and dashboard for sending letters, postcards and cheques programmatically, plus an address-verification API that is AMAS certified for Australian address data. It positions itself as built for developers, with operations in 8 countries.
Does PostGrid have a Shopify app?
Yes, one: PostGrid Address Verification, a free checkout address-validation app launched in December 2025 that verifies against USPS and Canada Post standards. It does not send direct mail. PostGrid's direct mail reaches Shopify through its REST API, Zapier or Klaviyo workflows that the merchant assembles.
Can PostGrid send abandoned-cart or win-back postcards from Shopify?
It can, if you build the flow: PostGrid's Zapier integration exposes Shopify triggers, including New Abandoned Cart, that can drive a Create Postcard action, and its Klaviyo integration triggers mail from Klaviyo workflows. There is no pre-built abandoned-cart or win-back campaign product; the trigger logic, offer, holdout and attribution are yours to design.
Does PostGrid price in Australian dollars?
Its published per-piece rates are in USD, even on the postgrid.com.au pricing page, whose own footnote says all prices are in USD and to contact sales for local currency. The published starter tier is US$0 per month with per-piece rates from about US$1.78 per postcard.
Is PostGrid or TouchDrop better for an Australian Shopify brand?
They sit at different layers. PostGrid is infrastructure a developer integrates: strongest for transactional and operational mail, cheques, address verification and multi-country sending. TouchDrop is a finished marketing product: pre-built win-back, abandoned-cart and post-purchase postcard flows from Shopify and Klaviyo events, printed and lodged inside Australia, billed in AUD with GST, with per-recipient attribution built in. If a marketer runs the channel, TouchDrop; if engineering is building custom mail into your systems, PostGrid.
Does TouchDrop validate Australian addresses?
Yes. Australian address validation, postcode checks and parcel-locker filtering run automatically on every campaign, alongside suppression lists and frequency caps, so undeliverable or unwanted mail is filtered before printing.
What does TouchDrop cost compared with PostGrid?
TouchDrop bills in AUD with GST included: a per-card rate set by plan plus a monthly platform plan. Current rates are on the pricing guide at touchdrop.com.au/guide/pricing. PostGrid publishes USD per-piece rates with a free starter tier and quote-based enterprise pricing.
