What You Get With the Integration
If you're a Postscript customer using Shoptin, you can now grow your SMS list with Postscript's Onsite Opt-in. You'll get:
Postscript's patented Onsite Opt-in and Onsite Opt-in Reminder, trusted by thousands of top Shopify brands, now available with Shoptin
Every opt-in flowing straight into Postscript, so new subscribers are AI-eligible from day one and ready for Shopper
More SMS subscribers from the site traffic you already have, without trading off conversion, compliance, or subscriber quality
Where Shoptin Fits
Shoptin focuses on checkout. It detects each shopper's region, shows consent language optimized for that location, and goes live in minutes with no code or developer work. As privacy rules shift, it keeps that consent current for you.
That focus is exactly why the pairing works. Shoptin owns the email consent moment at checkout. Postscript's Onsite Opt-in brings compliant, high-quality SMS capture to the same shoppers. You don't trade one for the other. You run both.
Onsite Opt-in, Beyond Postscript
Bringing Onsite Opt-in to Shoptin is part of a bigger shift in how we think about list growth.
Onsite Opt-in started as a Postscript feature. It's becoming a standard for compliant, high-quality SMS capture across the tools Shopify brands already use. Extending it to partners like Shoptin does a few things:
Brings a compliant opt-in method to more merchants, wherever they capture subscribers
Gives brands more choice in how they build their stack, without tradeoffs between the tools they like and the results they need
Keeps new subscribers AI-eligible from the start, ready to put to work in Shopper right away
We'll keep investing in native Postscript surfaces. We'll also keep meeting merchants where they already grow.
