# The Best Free Shopify Apps Worth Installing Source: https://merchantstackdaily.com/blog/2026-11-06-best-free-shopify-apps.html Field guide November 6, 2026 **Start with Shopify's own free tools, then add only what they cannot do. Shopify Messaging covers the first 10,000 emails a month, Shopify Forms and Inbox are free, Flow automates the repetitive work, and Klaviyo's free plan covers 250 contacts. The free plan ends at a contact count, an order count, or a send count, and the page should name the limit, not the word free.** ## Free has four meanings, and the listing tells you which The pricing label on a Shopify App Store listing means four different things, and the first job is reading it. Free means no paid tier, and most of Shopify's own apps sit here. Free to install means installing costs nothing and using it might, with additional charges after a monthly allowance. Free plan available means a real free tier with paid tiers above it, where the limits live. Free trial available is not free: the app starts billing when the trial ends. A post that calls all four free is a post that will cost its reader money. The rule that follows is simple. Price the stack at the order volume you expect in six months, not the volume you have today, because most free plans cap orders, contacts, or sends, and each app costs more as you grow. ## The Shopify-native free stack Shopify Messaging, the app formerly called Shopify Email, is the easy start for email. It offers templates, segmentation, and automations, and the first 10,000 emails each month are free, then $1 per 1,000 emails after that. It also handles SMS and WhatsApp campaigns, with separate pricing for those channels. For a store under a few hundred orders a month, it covers newsletters, a welcome email, and abandoned checkout reminders without another subscription. Shopify Forms is free, adds pop-up and inline sign-up forms, and sends new subscribers straight to Shopify Messaging. The help page says a store can have up to 25 forms. Shopify Inbox is free live chat that links to orders and products, so a merchant can answer where's my parcel without opening another tab. Shopify Flow is free no-code automation, with hundreds of workflow templates: tag high-value customers, alert when stock runs low, hide sold-out products, flag risky orders. Shopify Search and Discovery is free, adding filters, synonyms, product boosts, and related recommendations, and it replaces a paid search app for most catalogues. ## Where the third-party free plans earn their place Klaviyo is the deeper email option. The free plan covers email for up to 250 contacts and up to 150 SMS credits, and it already includes templates, sign-up forms, segmentation, personalization, and A/B testing. Paid email starts at $20 a month for 251 to 500 contacts. The upgrade is worth it when the store wants flows driven by browsing and purchase behavior, which Shopify Messaging does not do as deeply. Judge.me is the default reviews app, the most-reviewed app on the store with a 5.0 rating from more than 48,000 reviews, and its free plan is unusually generous: unlimited product and store reviews, unlimited photo and video reviews, the review widget and star rating badge, carousels, Google reviews sync, and rich snippets. Smile's free plan covers up to 200 orders a month with a functional points and rewards program. The pattern is the same in each case: the free plan is real, the limit is a count, and the count is printed on the listing. ## The stack to install, in order Install in this order, and stop when the job is covered. Shopify Messaging for email, Shopify Forms for sign-ups, Shopify Inbox for chat, Shopify Flow for automation, Search and Discovery for search, Judge.me for reviews. Then add Klaviyo when the contact list passes 250 and the flows need to be smarter, and Smile when loyalty needs points and tiers. Every app in that list is free to start, and every one of them earns its script weight or gets uninstalled. An app that slows the storefront and does nothing measurable is not free. It costs conversions. ## Related reading If this topic is useful, these earlier guides go deeper on connected questions: [Shopify Flow Explained: Triggers, Conditions, and the Automations Worth Keeping](https://merchantstackdaily.com/blog/2026-11-05-shopify-flow-explained.md), [Shopify POS Explained: What the Register Actually Does](https://merchantstackdaily.com/blog/2026-11-04-shopify-pos-explained.md), and [Your Apps Are an INP Problem Before They Are a Features List](https://merchantstackdaily.com/blog/2026-11-03-app-scripts-inp-cost.md). ## Frequently asked questions ### What are the best free Shopify apps?
