What Push Notification Data Tells Us About CRO

As performance marketers and ecommerce operators stare down the back half of 2025, the question isn’t just “how do we get more traffic?”—it’s “how do we convert better and retain longer?”

At Reactiv, we’ve been focused on helping brands do exactly that. Since our launch in October 2024, Reactiv has powered mobile shopping experiences for DTC brands through Reactiv Clips—a lightweight version of a mobile app that doesn’t require a full download or opt-in to function. 

Once a shopper engages with a clip, it enables you to send push notifications for up to 8 hours (without requiring an opt-in). The results we’re seeing across our customer base suggest that push, when done right, is one of the most impactful conversion levers heading into the last part of the year and into 2026.

What We’ve Seen: The Case for Push-Driven Retention

Here’s what our aggregated data from late 2024 and into H1 2025 shows:

• Customer retention is 3–4x higher on Reactiv-powered mobile apps compared to traditional mobile web.
• Repeat purchases are 3–6x higher, driven largely by remarketing flows like push notifications.
• Push notifications sent through Reactiv Clips see 60% open rates on average, with 5–7% conversion rates.

Brands are also lowering CAC by 75% and increasing their profit per session by converting up to 3-5x more. 

This is because, unlike SMS or email, Reactiv Clips lets brands engage with buyers not just once, but twice or three times after they click an ad—lowering friction and giving marketers more control over the moment of conversion.

Timing Matters: Why Late-Night Pushes Win

When you send a push notification matters just as much as what it says. 

Based on Reactiv data, the highest conversion window is between 9PM and midnight—when shoppers are relaxed, scrolling, and more receptive to reminders.

It’s not hard to imagine why: at 9AM, a push about a jacket you were browsing is easy to swipe away while rushing to work. But at 10:30PM, that same message might feel like just the right nudge to complete the purchase. 

We see conversion rates peak at 6.8% during this window, and recommend brands lean into it as part of their evening remarketing strategy.

Four Types of Push Notifications That Actually Work

There’s more than one way to use push notifications effectively. Based on top-performing flows from Reactiv merchants, here are four notification types that consistently drive results—and when to use them.

1. Promotional Pushes That Spark Urgency

These are your classic campaign drivers: product drops, limited-time offers, site-wide sales. According to Airship, 65% of mobile app users open notifications offering a deal. We see similar behavior across Reactiv—especially among repeat customers who are already familiar with the brand. These work best when they create a sense of exclusivity or time sensitivity, like “Early access just for you” or “Ends at midnight.”

2. Behavioral Nudges That Reclaim Lost Sales

Cart abandonment rates have crept up to over 70% globally, and mobile browsing behavior means many shoppers don’t convert on their first visit. Behavioral pushes—those tied to product views or carts—can bring users back at the right time. On Reactiv, these messages outperform email by 37% in click-through rates. Simple nudges like “Still thinking it over?” or “You left something behind 👀” can make the difference between a bounce and a buy.

3. Transactional Updates That Build Trust

Post-purchase doesn’t mean post-communication. In fact, 90% of shoppers want to track their packages in real time. Push notifications with order confirmations, shipping updates, and delivery ETAs reduce WISMO tickets and increase satisfaction. These messages keep customers in the loop—and more importantly, keep them in your ecosystem.

4. Lifecycle Messages That Build Community

Push is also a powerful tool for reinforcing brand affinity. Notifications tied to loyalty programs, birthdays, or just regular check-ins can deepen emotional connection. Brands like Top of the Mornin’ Coffee use lighthearted pushes—like “Just stopping by to say you’re awesome”—to stay top of mind and build goodwill between purchases. Think of these as digital touchpoints that build habits and community.

Unlocking Push Without the Opt-In

Here’s what makes Reactiv’s approach unique: with Reactiv Clips, brands can send push notifications without requiring a download or opt-in.

A Reactiv Clip is a lightweight mobile experience that can be launched from an ad, email, or link. Once a user opens a Clip, brands have an eight-hour window to send personalized push notifications.

This turns every ad click into a remarketing opportunity. 

A Typical Journey Looks Like This:

• A customer clicks on a social ad → a Reactiv Clip opens the product page
• The user browses but doesn’t buy → a behavioral push notification is sent later 
• They click the notification → return to the Clip → complete the purchase
• A post-purchase push confirms their order and keeps them engaged

All of this happens without the user downloading an app or opting into notifications. 

What to Prioritize Now and Beyond

Based on everything we’ve seen, here’s what we recommend as brands head into the back half of the year and into 2026:

• Lean into push notification remarketing. Especially behavioral and late-night campaigns.
• Personalize whenever possible. The delta in performance between targeted and untargeted is too large to ignore.
• Rethink app strategy. If you don’t have the install base or opt-ins to use push, consider lightweight options like Reactiv Clips to bridge the gap.
• Think beyond the sale. Push isn’t just for conversion—it’s also for community-building, loyalty, and customer experience.

Mobile apps and push are no longer a channel reserved for massive brands. They’re an essential part of a modern CRO playbook—and one of the most underutilized tools in ecommerce.
