Everything you need to grow an engaged and compliant SMS list
Acquisition tools
Build and grow your SMS list with the help of Postscript.
Desktop and mobile popups
Collect both phone numbers and emails. Customize the design to match your brand, choose the type of incentive you want to offer, and select when and where on your site you want your popups to appear.
Keywords
Create an unlimited number of text-to-join keywords to share across all your marketing channels. Use keywords to track opt-ins and revenue generated from different marketing channels or campaigns.
Checkout collection
Collect SMS subscribers on our checkout pages. This includes the Shopify and Shopify Plus checkout, ReCharge, Carthook, or a custom checkout page integrated with Postscript.
Landing page and opt-in form
Create a landing page with an SMS opt-in form that you can link to from email campaigns or social media posts. This includes two-touch technology on mobile.
QR codes
Create unique QR codes for your product packaging and in-person experiences that people can scan to opt-in to your SMS list.
Back in Stock
Grow your subscriber list with high-intent shoppers using Postscript's Back in Stock list growth tool and automation. When products on your site go out of stock, shoppers will see a link or banner to sign up for SMS notifications when the item goes back in stock. Instead of losing sales, you can gain a subscriber.

SMS Marketing Compliance
All of Postscript’s features and acquisition tools are hard-wired to follow guidelines set by the TCPA, mobile carriers, and other regulatory bodies where possible. For instance, we include automated compliance language on popups, opt-in forms, and checkout collection. For acquisition tools where it’s not possible to automatically include compliance language (such as Keywords) we provide clear guidelines in our platform and help articles. As compliance regulations evolve, so does our platform to help you stay compliant automatically. Learn more about compliance here.
