Postscript is one of the most popular SMS marketing platforms for Shopify. Combined with Checkout Links, you can send subscribers directly to a pre-loaded checkout with one tap.

​
How It Works

  1. Create a checkout link with your product and offer
  2. Add the link to your Postscript campaign or automation
  3. Subscribers tap and land directly at checkout
No cart page. No product browsing. Straight to purchase.

​
Setup
