Shopify covers the core of running an online store, but the right add-on tools fill the gaps — product sourcing, email marketing, and on-site conversion in particular. Here's what we'd recommend in 2026.
1. Shopify
Shopify itself remains the most widely used platform for building and running an online store, with a large app ecosystem covering nearly anything you'd want to add — shipping, subscriptions, reviews, and more.
2. Sell The Trend
Sell The Trend integrates directly with Shopify, letting you find trending products and add them to your store without leaving the research tool.

3. Klaviyo
Klaviyo is one of the most widely used email and SMS marketing tools built specifically for e-commerce, with deep Shopify integration for behaviour-triggered campaigns (abandoned cart, post-purchase follow-up, and similar).
Pricing: free tier available; paid plans scale with subscriber count.
4. Privy
Privy focuses on on-site conversion — pop-ups, banners, and email capture forms designed to turn more visitors into subscribers or first-time buyers.
Pricing: free tier available; paid plans for advanced features.
Building your Shopify toolkit
For product sourcing, Sell The Trend plugs directly into Shopify. For turning traffic into customers and repeat buyers, Klaviyo (email/SMS) and Privy (on-site capture) cover the two ends of that funnel well.
