Best Shopify Apps to Increase Sales

Here at Postscript we love serving Shopify store owners. We aspire to help them grow their businesses. To that end, here’s a few of our favorite apps we recommend for helping stores grow revenue:

  • Klaviyo is one of our absolute favorite apps, and is a leader in the marketing automation space (email + social especially). It’s easy to use, extremely powerful, and comes chalk full of best practices and content examples for you to pull from.
  • Boost Sales is a tool for upselling and cross selling relatable products in your store, which can significantly increase order value.
  • Refersion is an affordable affiliate toolkit that also comes with a marketplace of affiliates and influencers to help get you started.
  • Printful is an extremely impressive print-on-demand operation. Their shopify integration is easy-to-use and enables entrepreneurs to quickly design and fulfill original designs.
  • Postscript of course! (Shameless plug). Postscript auto-syncs with shopify stores, giving them the ability to send campaigns or automations to their audience via SMS. It’s cost efficient and sees extremely high engagement rates (CTRs over 50%). Plus, it’s a mobile revenue channel.


In our experience these are some of the best Shopify apps for increasing sales. Try one (or all) and see what they can do for your business!
