About Upsell SMS

Upsell SMS began with a simple observation: despite all the advances in e-commerce technology, merchants were still leaving significant revenue on the table during one of the most critical moments in the customer journey — immediately after purchase.

Our founders, experienced Shopify merchants themselves, noticed that traditional upsell methods like email and pop-ups were falling short. Email open rates were too low and often too slow, while pop-ups couldn't reach customers who shopped on mobile or left the site after checkout.

The breakthrough came when they started experimenting with SMS for post-purchase communication. The results were immediate and dramatic — SMS messages had near-perfect open rates and caught customers at their peak excitement about their purchase.

What began as an internal tool for their own Shopify stores quickly gained attention from other merchants facing the same challenges. In 2023, the team decided to develop their solution into a full-fledged product that any Shopify merchant could use.

The key innovation came when they developed the one-click technology that allowed customers to add upsell items to their order without re-entering payment information — removing the biggest conversion barrier in post-purchase upsells.

Today, Upsell SMS is helping thousands of Shopify merchants increase their Average Order Value with SMS-based post-purchase upsells that convert at rates 10x higher than traditional methods. The company continues to innovate with new features that make upselling more effective and easier to implement.
