Dataships Checkout Opt‑in vs Postscript SMS Marketingfor Shopify (2026)
Dataships Checkout Opt-in and Postscript SMS Marketing both aim to enhance merchant communication, but they approach the task from different angles. Dataships focuses on maximizing email and SMS opt-ins *at the checkout stage* while ensuring compliance with privacy regulations. Its strength lies in dynamically adapting consent forms based on visitor location and integrating tightly with checkout processes to force multiply retention efforts. Postscript, on the other hand, is a broader SMS marketing platform. Postscript SMS Marketing, with its significantly larger user base indicated by the higher number of reviews, likely provides a more comprehensive suite of SMS marketing features beyond just opt-in collection. While the Dataships description highlights dynamic consent management and Klaviyo integration, Postscript's description (unprovided but implied) likely encompasses campaign management, automation, segmentation, and potentially other marketing channels as well. The difference is that Dataships is hyper focused on the checkout opt-in experience, whereas Postscript is a wider SMS marketing solution.

Our Verdict
If a merchant is primarily focused on optimizing their checkout flow for compliant email and SMS opt-ins and already uses Klaviyo, Dataships Checkout Opt-in would be the better choice. Its focus on dynamic consent and seamless integration suggests it will excel in this specific area.
However, for merchants looking for a complete SMS marketing solution that includes campaign creation, automation, segmentation, and potentially other channels, Postscript SMS Marketing is likely the more suitable option. The large number of reviews suggests a mature and feature-rich platform, even if the initial data doesn't explicitly state its capabilities.
