See why leading Shopify brands are graduating to Postscript SMS from Klaviyo.

We’ve heard repeatedly from top brands that they come to Postscript for the better product and stay for the higher quality and hands-on support.
Here’s why.

Klaviyo was built specifically for email marketing.

Email and SMS are not the same—so why would you trust them to the same platform?

Postscript was built specifically for SMS marketing. It’s all we do.
That’s why 10,000+ Shopify and Shopify Plus merchants trust us to:

  • Act as an extension of their own marketing team to free up team member bandwidth for small and large teams alike.

  • Maintain and expand on a robust integration with Klaviyo so they can execute a cohesive and complementary communication strategy across email and SMS.

  • Provide the tools and latest compliance updates so they can send texts compliantly, avoiding costly litigation.

  • Price our services transparently based on messaging usage—not credits.

“We moved from Klaviyo SMS to Postscript for the increased functionality and have stayed for the high level of service from the Postscript team. We have partnered with several third party platforms for multiple areas of the business, and Postscript delivers a higher level of customer service than any of them. I recommend Postscript on a regular basis to my network in the DTC ecommerce space and view them as an essential part of any SMS strategy.”

Our team analyzed the Shopify data of dozens of stores 90 days before migrating from Klaviyo’s all-in-one platform to Postscript’s best-in-class platform. We then analyzed the Shopify-sourced data 90 days after migrating and adjusted for seasonality to normalize the data.

We saw that brands who graduated to Postscript for SMS increased their overall revenue by 15%.

How Chomp creates a personal shopper experience over text

By leveraging Postscript’s segmentation and personalization capabilities to the fullest, CHOMPS built a contextual SMS strategy that quickly exceeded revenue expectations. Fueled by a phone-first website popup, redemption of their new-subscriber incentive skyrocketed—leading to more net new customers and more opportunities to drive loyalty and repeat purchases. The cherry on top? For the first time ever, CHOMPS sold out of inventory during their BFCM early access sale—all thanks to promotion on SMS.
