Next, we’ll explore why Insider can be a great alternative to OneSignal if you’re looking to take your customer engagement efforts to the next level.
Benefit #1: Access to 12+ channels and advanced personalization tools
Insider gives you unmatched channel breadth — from email, SMS, and WhatsApp to on-site, mobile apps (iOS and Android), digital ads, and much more.
This ensures you can reach and engage customers on their preferred touchpoints. Just as importantly, our platform lets you personalize your efforts across these channels for maximum relevance and engagement.
For example, here are some elements and channels you can personalize with our platform:
- Web and mobile app product recommendations through various recommendation strategies — like location-based bestsellers, frequently purchased together, or new arrivals. Our AI can also combine different strategies to achieve the best-possible results. Example: Avon used our product recommendations to achieve a 78% increase in conversions.
- Emails by easily adding customers’ names, birthdays, cart items, or personalized product recommendations in each email to increase open and clickthrough rates. Plus, our platform supports AMP emails, so you can create web-like experiences that allow customers to browse items, answer questions, and make reservations without leaving your emails.
- Messaging channel communications across SMS, WhatsApp, Facebook Messenger, Instagram, and more. You can send promotional messages, transactional updates, price drop alerts, back-in-stock alerts, and event reminders. You can also have AI-powered, two-way conversations at scale to market, sell, and answer customers’ questions quickly.
- Web and mobile push notifications, including recurring, carousels, cart reminders, in-stock alerts, and many others. These can be personalized to drive engagement and revenue in a cost-effective way. Example: Marks & Spencer used our web push notifications to achieve a 15.1% cart recovery rate, which is 353x higher than the industry average.
- Site search results via Eureka — our AI-powered site search and merchandising tool. This is a great way to improve conversion rates, reduce bounce rates, and increase average order value (AOV) by ensuring all visitors find what they’re looking for as fast as possible.

Benefit #2: AI-powered omnichannel marketing automation.
Besides just getting access to a plethora of channels, Insider’s customer journey builder lets you create and automate personalized campaigns across these touchpoints.The process is controlled via a simple drag-and-drop editor that anyone can use. You can also leverage one of our many premade templates to launch campaigns as quickly as possible.
For example, you can trigger automated workflows or entire omnichannel campaigns via:
- Events, which can be any actions on your site or app, such as page visits, add-to-cart events, or completed purchases.
- Attribute changes, like a non-regular customer suddenly visiting a product three times a week.
- Price drops.
- And more.
From here, you can select channels, automation triggers, conditions, wait times, and much more. We’ve explored many journey orchestration strategies and ideas in the following guides:
Additionally, you can rely on our AI-powered tools for fast campaign creation and automatic optimization based on customers’ needs and preferences. These tools include:
- Send-Time Optimization and Next-Best Channel Selection, which analyze user behavior to determine the optimal send times and channels for each message.
- A/B Test Winner Auto-Selection, which analyzes the results of your A/B tests and automatically guides users to the winning variants based on a metric you’ve selected beforehand (e.g., like open rates, conversion rates, revenue, and so on.)
- Sirius AI which can build campaign segments, journeys, text, and images using text prompts. You can provide simple text prompts with your end goal and our Generative AI will do the heavy lifting of creating customer segments, omnichannel journeys, campaign copy, and images in a matter of seconds.
For a real-life example of Insider’s omnichannel potential, check out our case study with NA-KD.This brand unified their data in our eCommerce CDP to get a single source of truth for all customer-focused initiatives.
Then, NA-KD’s digital marketing team used our platform’s broad channel reach to launch hyper-targeted campaigns across email, SMS, WhatsApp, web push, and app push. This allowed them to reach customers with the right messages, on the right channels, and at the right times — e.g., while they were browsing the website, chatting on WhatsApp, or scrolling through social media.
Using this new approach NA-KD generated a 25% increase in customer lifetime value (CLTV) and a 72x ROI in 12 months.

Benefit #4: Unified customer data and streamlined marketing operations
Building effective and personalized marketing strategies is only possible with a solid understanding of your customers’ journeys. That’s why Insider helps you bring together all relevant customer data from different sources into a single convenient database via our customer data platform (CDP).
Our CDP can unify data from any online or offline source — including customer relationship management systems (CRMs), content management systems (CMSs), APIs, analytics platforms, point-of-sale devices, customer service tools, other CDPs, and more.
The CDP uses this unified data to create 360-degree customer views that give you insights into:
- Previous purchases and browsing histories.
- Channel reachability and integrations across different touchpoints like email, SMS, or WhatsApp.
- Predictive marketing characteristics, such as likelihood to purchase, likelihood to engage on a channel, discount affinity, and much more.
Having all customer data unified in one place removes the need to constantly jump between different tools and painstakingly integrate data sources.
This makes it much easier to launch high-converting campaigns. For instance, Spotlight Retail Group reduced its campaign launch times by 80% thanks to our CDP and Insider’s data activation channels.
