Most Shopify stores lose the same shoppers over and over. A visitor lands from an Instagram ad, adds a $60 candle to their cart, gets pulled away, and never comes back. If they didn’t leave an email or a phone number, you have almost no way to reach them. That’s the problem web push notifications solve, and it’s worth exactly as much as the automation you attach to it.
Who this is for
This guide is for the owner of a small Shopify DTC store, roughly 1 to 30 people, who wants a channel to bring anonymous visitors back without paying for retargeting ads or waiting to grow an email list. If you have fewer than a few thousand monthly sessions, none of these apps will noticeably move the number. The constraint is traffic, not tooling, and the hour is better spent on product pages, an upsell app, or a post-purchase survey that improves what happens after the click.
Our pick: Brevo PushOwl
The reason to pick PushOwl on a small Shopify store isn’t a single flashy feature. It’s that the free bundle covers the foundational web push work at no cost, with unlimited subscribers, welcome notifications, back-in-stock, and price drop included, while abandoned cart recovery, shipping, browse abandonment, and custom automation sit on paid tiers. That gap is exactly where the $19 Plus plan earns its keep: it unlocks abandoned cart recovery, which is typically the highest-ROI automation in any DTC marketing stack, and for most stores that’s the sweet spot.
The Shopify integration is the other reason. You connect it through the Shopify App Store, and the integration handles catalog import, real-time inventory sync, and order sync back to Shopify for fulfillment. That matters when the buyer is the owner and there’s no engineering time to spend.
The trade-offs are real. PushOwl’s branding appears on notifications on Free and Business plans, and removing it requires Enterprise, starting at $149/month, which is a steep price just for white-labeling. If a subtle “sent by PushOwl” line under a notification would kill your brand’s mood, budget for it. Advanced segmentation, the feature that separates strategic push marketing from spray-and-pray, is locked behind the most expensive plan too, so once you get serious about targeting, the cost jumps.
The runner-up: PushEngage
PushEngage is the pick if you want to pay less at the entry price and you’re curious about AI-generated push copy. The Business plan starts at $9/month for 1,000 subscribers, with Premium at $29/month and Growth at $39/month, and pricing scales by subscriber count with a free version and free trial available. The AI is documented rather than vague: AI credits are required to use AI-powered text generation, and you buy them from the Billing section of your dashboard starting at $10 for 5,000 credits (introductory pricing, with prices potentially rising based on demand). That’s more honest than the “AI-powered” marketing on most push app landing pages, because it says what you get and what it costs.
Two catches. The free tier is thin: PushEngage’s forever-free plan comes with 30 push notification campaigns, up to 200 subscribers, and a free WhatsApp click-to-chat widget with unlimited WhatsApp messaging, so a working store will move to a paid plan quickly. And the strongest cart-and-price automations sit high in the stack. The Enterprise plan is what gives you Smart Cart Abandonment Campaigns, Automatic Inventory Alert, Price Drop Alert, Custom Triggered Campaigns, Personalized Smart Tags, and unlimited sub-accounts for client sites. For a solo brand, PushOwl is simpler; for an agency or a brand that already lives in WhatsApp, PushEngage earns the second slot.
The budget pick: Firepush
If you’re testing whether push will do anything for your store at all, Firepush’s free plan is the easiest bet. The free plan includes 500 web push notifications per month and every push feature (abandoned cart recovery, welcome series, promotional campaigns, segmentation, analytics) with no credit card and no time limit. Paid plans, when you outgrow the free cap, start from $13/month and only raise the cost when send volume grows.
Watch two things. First, third-party reviewers are candid that Firepush is a multi-channel recovery layer covering web push, SMS, and basic email at a low entry price, with cart abandonment, price-drop alerts, and back-in-stock push as core strengths, but lifecycle depth for welcome, winback, and replenishment belongs elsewhere. It’s a budget recovery layer, not a full retention platform. Second, an active user complaint on the Shopify App Store is that pricing can jump sharply between tiers, so model the price at 1,000, 5,000, and 10,000 subscribers before you commit.
Also great: Hextom
Hextom is the pick if you already care about WhatsApp and SMS and want one Shopify app for all three. Hextom: WhatsApp, SMS & Push offers a Free plan, a Business plan at $15/month, and an Enterprise plan at $50/month, and it’s straightforward to set up. The app runs web push, SMS, and WhatsApp from one place with a smart balancing algorithm that sends each message through the best channel for that subscriber and avoids duplicates. The free plan gives unlimited subscribers, 1,000 free monthly web push sends, back-in-stock and price-drop automation, and a subscriber-collection tool.
The catch, and it’s the same catch across the category, is that “free plan available” reads better than “free plan usable.” The features most owner-operators need (abandoned cart recovery, campaign scheduling, higher send volumes) sit on Business or Enterprise. If SMS is going to be the second channel you actually use, our take on Klaviyo vs Mailchimp covers where email lives in this stack; Hextom is the light, cheap counterpart on the push and WhatsApp side.
The power option: OneSignal
OneSignal is the most technically capable platform in this group and the worst fit for a small Shopify store. The Growth plan costs $19 per month plus usage by channel: mobile push is billed monthly at $0.012 per MAU with in-app messaging included and no limits on impressions, and web push is $0.004 per web push subscriber. That published, usage-based pricing is genuinely useful, and the free plan is generous for validating a channel.
The reason it isn’t higher is fit. OneSignal was built for product teams sending push from mobile apps, not for Shopify owners chasing an abandoned candle cart. The pre-built Shopify triggers other apps ship (one-click cart recovery, back-in-stock, price drop) are simpler to turn on in PushOwl or Hextom. And the free plan is getting tighter. Starting September 1, 2026 for new customers and October 1, 2026 for existing customers, the Free plan introduces a 1,000 monthly active user limit per organization for mobile push and in-app messaging. Web push and email continue under their existing Free plan limits regardless of MAU. Notifications fire at 75%, 90%, and 100% of the limit, and if you go over you have 24 hours to upgrade before mobile push and in-app sending pauses.
How to choose
The decision is shorter than the comparison tables make it look. If you’re on Shopify, want push to feel like a Shopify-native tool, and want cart recovery working by the end of the afternoon, pick PushOwl and skip the rest. If your list is smaller than 200 subscribers and you want to try push before paying, install Firepush’s free plan. If you already run WhatsApp and want one dashboard for everything, Hextom is the cheaper starting point. If you want AI-generated push copy as a priced feature rather than a marketing line, PushEngage. And if you’re running a mobile app alongside your store and want one platform for both, OneSignal, with your eyes open about the September 2026 free-tier change.
We wouldn’t run more than one of these at a time on a small store. Pick the one whose free tier already does what you need, and move to its cheapest paid plan the month abandoned cart recovery starts earning back the fee.
