The future of Lifecycle Marketing is autonomous.

The future of Lifecycle Marketing is autonomous. By George Deglin, Co-founder & CEO For more than a decade, customer engagement platforms have offered the same deal: OneSignal hand you a powerful dashboard, and you supply the people, the time, and the expertise to run it. The more capable the platform got, the more of all three you needed. Sophistication meant headcount. Growth meant more budget. UIs got more buttons and more screens. That deal is ending. Dashboards are dying. OneSignal is now building toward Autonomous Lifecycle Marketing (ALM). The premise is simple, even though the engineering behind it isn't: you connect OneSignal to your product, and its software plans, sends, tests, and improves the messages that onboard, engage, and retain your users. You set the goals, the brand, and the guardrails. OneSignal does the work. All the time, continuously. While you're outside. While you're eating lunch. Even while you sleep. This is a real bet, and I want to be direct about it. OneSignal believe the center of gravity in its category is moving from marketers operating software to software operating the full customer lifecycle, with people and AI agents supplying goals, context, and approvals. The platforms built for the dashboard era were designed around a human clicking through every step. OneSignal is designing for a world where most of that work is done for you, and you step in where your judgment actually matters. The autonomy ladder. Nobody hands the keys to an autonomous system on day one, and they shouldn't. Trust is earned in steps, and so is autonomy. Here's how OneSignal think about the climb: * L0 - Manual. The dashboard. A marketer drives every click, and the team scales by hiring. This is where the entire category has lived. * L1 - Assistance. AI drafts copy, suggests audiences, and explains your analytics in plain language. Input is required. You review and ship. This is live today. * L2 - Expert Assist. AI is proactive... It recommends campaigns to fill lifecycle gaps, flags mistakes, and checks your work. Input is still required. * L3 - Agentic Autopilot. You delegate bounded work, and AI does it within the scope and rules you've defined. You approve in large chunks. * L4 - Full Operator. You set your goals and the guardrails. AI plans, sends, tests, and improves the campaigns against it, and reaches out only when it needs you. L4 is the vision, not the present. But there's real value from AI today, and OneSignal see that value growing daily. OneSignal is already climbing. Two products OneSignal has shipped are the first real steps up that ladder, and they reflect two different ways its customers want to work. OneSignal AI offers assistance inside the platform. You can ask how a campaign performed last week, have it draft a journey to re-engage lapsed users, tell it to send a thank you email to recent sign ups users: all in plain language. It knows the page you're on and can answer questions about what you're actively working on at. It can build a journey, compose copy, and provide benchmarks and industry best practices. OneSignal has also introduced Brand Center, to ensure you can reflect your brand, logo, tone, color palette, etc. even when you're moving at the speed of automation. Today, OneSignal AI graduates to Open Beta. "I love OneSignal AI. If I've got a Journey with seven push notifications, I can just ask how my onboarding is performing and it spits out all the results, instead of digging through templates and reporting manually. One prompt probably saved me two hours of work, and it came back in 10 seconds." - Laura Allison, CRM Manager, DC Thomson The OneSignal MCP Server brings OneSignal's capabilities to the AI tools and agents you already use. Built on the open Model Context Protocol (MCP), it lets AI assistants like Claude, ChatGPT, Cursor, and Copilot securely operate OneSignal on your behalf. You can take actions across the entire OneSignal API, with one deliberate exception: OneSignal don't allow delete actions. And as a general safeguard, high-impact actions like sending a message require explicit confirmation. The MCP server unlocks something the dashboard never could: orchestration across your entire tech stack with no 1st party integrations required. In a single conversation, an agent can pull behavioral data from your data warehouse, find where new users drop off in an analytics tool, build a segment in OneSignal, draft the copy, and schedule the sends: coordinating across every tool that speaks MCP, not just ours. That's what an AI-native workflow actually looks like, and it's in Open Beta now with availability in both Cursor and ChatGPT marketplaces. Updates to the free plan: continuing its mission of democratizing customer engagement. OneSignal has always allowed users to sign up and use the product for free. This enables OneSignal to collect feedback from a broad set of users and use cases that forces OneSignal to build a product that is equally intuitive and powerful. As OneSignal bring AI features to market OneSignal want to make sure those can be used by everyone. Free plan users will have access to additional journeys, unlimited message steps, and more data tags alongside its new AI capabilities to drive powerful, personalized automated lifecycle marketing. To sustainably offer these additional features OneSignal is introducing a MAU (Monthly Active User) cap on the free plan. These changes will be rolled out in the coming months. Its differentiated approach. Outcomes first. OneSignal believe many other customer engagement platforms are racing to win on ever-deeper 1:1 personalization. OneSignal think personalization can be made infinitely deep, but not without hitting a point of diminishing returns. What its customers actually want is the outcome: more activated users, more revenue per install, less churn. OneSignal optimize for the best result with the least effort, not the most elaborate configuration with the most. Built for mobile-first teams. OneSignal has always built for mobile-first B2C companies with serious lifecycle needs. OneSignal started as a mobile game studio and built its own software to engage users. Today OneSignal is the best tool for companies doing that same work: driving activation, monetization, and retention with their mobile users. The system gets smarter at scale. Its low barrier to entry means OneSignal work with more businesses, of greater variety, than its competitors do. That scale is a learning advantage: OneSignal understand the goals and tactics that achieve outcomes with AI across the spectrum of businesses that OneSignal work with. Its unique understanding of which lifecycle strategies actually produce results is an advantage OneSignal share with all of its customers. The original version of its platform already drives the outcomes ALM is built to compound: Cashea lifted first-month activation 43% and Letgo reactivated more than 28,000 dormant users from a single campaign. Now imagine that work running continuously, on its own. The promise. OneSignal is building a lifecycle marketing function that's future-proofed for an AI-native world, with lower operating cost, less manual work, and outcomes that improve as both AI and its platform evolve. The send button will always exist. But more and more of what surrounds it (the planning, the testing, the tuning, the late-night "did that campaign actually go out, and how did it do?") will be handled. OneSignal AI and the MCP are continuing to improve and OneSignal is learning from their real usage every day. More capabilities are on the way. If you're already building with AI day to day, this is the moment to get in early and tell OneSignal what works and what doesn't. OneSignal is listening, and OneSignal is building fast. The dashboard era was about giving you better tools. This next era is about giving you the outcomes those tools were always for, and handing back the time you spent operating them.

OneSignal unveils Autonomous Lifecycle Marketing vision, opens OneSignal AI and MCP Server to all users.

OneSignal unveils Autonomous Lifecycle Marketing vision, opens OneSignal AI and MCP Server to all users. July 14, 2026, 12:45 GMT Customer engagement platform sets course to autonomous lifecycle marketing that continuously improves itself, with OneSignal AI and MCP available today. The dashboard era was about giving marketers better tools. This next era is about delivering the outcomes those tools were always for, and handing back the time spent operating them." - George Deglin, co-founder and CEO, OneSignal SAN MATEO, CA, UNITED STATES, July 14, 2026 / EINPresswire.com / - OneSignal, the customer engagement platform trusted by more than one million businesses, today announced its vision for Autonomous Lifecycle Marketing (ALM): a self-improving platform that plans and executes messaging campaigns that onboard, engage, and retain a brand's users, all while maintaining a marketers control to set the strategy, goals, brand, and implement guardrails. Alongside the vision, the company released OneSignal AI and the OneSignal MCP Server into open beta, available to every OneSignal account starting today. For over a decade, lifecycle marketing platforms have offered the same deal: a powerful dashboard, run by the people, time, and expertise a company can supply. As platforms grew more capable, they demanded more of all three - putting sophisticated lifecycle marketing out of reach for the lean growth teams behind most consumer apps. OneSignal is building toward the opposite: software that does the work, so a team of five can operate like a team of twenty-five. "The center of gravity in our category is moving from marketers operating software to software operating the customer lifecycle, with people supplying goals, context, and approvals," said George Deglin, co-founder and CEO of OneSignal. "The dashboard era was about giving marketers better tools. This next era is about delivering the outcomes those tools were always for, and handing back the time spent operating them. The products we're opening up today are the first real steps up that ladder." Available today in open beta OneSignal AI is an AI assistant built into the OneSignal platform. In plain language, marketers can create push notifications, emails, in-app messages, and SMS; build segments and multi-step Journeys; get reporting on message and Journey analytics and trends; and receive recommendations and industry benchmarks. The OneSignal MCP Server brings OneSignal's capabilities to the AI tools and agents teams already use. Built on the open Model Context Protocol (MCP) with OAuth support, it lets AI assistants such as Claude, ChatGPT, Cursor, and Copilot securely operate OneSignal on a customer's behalf - spanning messaging, users and subscriptions, segments, templates, exports, and analytics. In a single conversation, an agent can pull behavioral data from a warehouse, find where new users drop off, build a segment in OneSignal, draft the copy, and schedule the sends. The autonomy ladder OneSignal frames the path to autonomy as a ladder marketers climb as trust is earned: from manual dashboards and AI assistance, to proactive expert assistance delegated agentic autopilot, and ultimately a full operator that runs an entire lifecycle program against a company's goals and reaches out only when it needs a decision. The outcomes ALM is built to compound are already proven on OneSignal's platform: fintech app Cashea lifted first-month activation 43%, marketplace letgo reactivated more than 28,000 dormant users from a single campaign, and health app BetterMe lifted retention 22%. About OneSignal OneSignal is the market-leading customer engagement platform for mobile and web push notifications, email, SMS, RCS, in-app messaging, and Live Activities.

OneSignal + Shopify: connect your store to cross-channel messaging in minutes.

OneSignal + Shopify: connect your store to cross-channel messaging in minutes. Your Shopify store already knows a lot about your customers. What they browse, what they add to cart, what they buy, what they abandon, how much they've spent over time. The problem is that this data usually stays locked inside Shopify, disconnected from the messaging tools you use to actually communicate with those customers. OneSignal's Shopify integration, powered by its certified partner Vendo, closes that gap. It automatically syncs your Shopify customer data, storefront browsing events, and server-side order events into OneSignal, where you can use them to trigger messages, build segments, personalize content, and power automated journeys across push, email, SMS, and in-app. Setup takes minutes and there's no custom development required. What data gets synced. The integration pulls data from two sources and sends it all to OneSignal as user tags and custom events, which means it's immediately available for segmentation, personalization, and journey triggers. Customer tags. These are properties attached to each identified customer profile in OneSignal. They update automatically every hour: * Name, email, and phone number * Lifetime spend and total order count * First and last order dates * Email marketing consent status * Shopify customer tags (any tags you've applied in Shopify) Client-side events (real-time). These fire in real time as customers browse your storefront, captured via the Shopify web pixel: * Page viewed, product viewed, collection viewed * Search submitted * Product added to cart, product removed from cart, cart viewed * Checkout started, checkout contact/address/shipping/payment info submitted, checkout completed Server-side events (payment-verified). These come from Shopify's backend and capture the full order lifecycle: * Order received, fulfilled, and delivered * Order refunded or partially refunded * Abandoned checkout (syncs every hour) How to set it up. The setup is genuinely quick. There are four steps, and none of them require writing code or editing your Shopify theme: 2. Connect your OneSignal account by entering your OneSignal App ID and REST API key in the Vendo dashboard. 3. Choose which events and tags to sync and configure your web push settings (prompt style, notification icon, etc.). Once enabled, data starts flowing. Vendo also runs a historical backfill, so OneSignal receives your existing customer data and recent order history right away. You don't start from zero. 4. Enable the Vendo theme block in your Shopify theme settings (Online Store > Themes > Customize > App embeds > toggle Vendo on). This handles SDK initialization, push prompts, user identification, and tag syncing automatically. How customer identity works. An important detail: the integration uses an identified-only approach to user tracking. Anonymous visitors who haven't taken an identifying action are not tracked. A customer becomes identified (and starts generating data in OneSignal) when they do one of the following: This approach is intentional. It prevents the duplicate user profiles and ensures that every profile in OneSignal represents a real, reachable customer. If a visitor subscribes to push and later logs in, Vendo merges the two identities automatically so you don't end up with separate profiles for the same person. What you can build with it. Once your Shopify data is flowing into OneSignal, you have the building blocks for the campaigns and automations that drive real eCommerce revenue. Here are the most common use cases: Abandoned cart recovery. Trigger a push notification or email within an hour of a customer abandoning checkout, personalized with the products they left behind. This is typically the highest-ROI automation you can set up, and the abandoned checkout event makes it straightforward to build as a Journey in OneSignal. Post-purchase journeys. When an order is placed, kick off an automated sequence: a thank-you message, a shipping update when the order is fulfilled, a delivery confirmation, and a follow-up a week later asking for a review or cross-selling related products. Each step maps to a server-side event that's already syncing. Win-back campaigns for lapsed customers. Segment customers whose last order date is more than 60 or 90 days ago and re-engage them with a targeted offer across email, push, or SMS. The last_order_date tag makes this segment easy to build and it updates automatically. VIP and loyalty targeting. Use the total_spent and order_count tags to create segments for your highest-value customers, then send them early access to sales, exclusive offers, or personalized product recommendations. Web push for your storefront. The integration deploys OneSignal's web push SDK on your Shopify store with no code. Visitors can subscribe to push notifications directly from your storefront, and you can start re-engaging them immediately, even if they never created an account or provided an email address. Pricing. The Vendo integration is available on three tiers, all of which include the full set of data syncing, event tracking, and web push deployment: | Plan | Details | | Startup ($25/month) | Up to 1,000 orders/month. Email support. | | Growth ($100/month) | Up to 12,500 orders/month. Standard onboarding support. | | Scale ($250/month) | Up to 50,000 orders/month. Premium support. | You can purchase through the Shopify App Store or directly from OneSignal. The pricing is the same either way. Note that the Vendo integration fee is separate from your OneSignal plan. Additional usage fees may apply if your order volume exceeds your plan's allotment. Get started. If you're already on OneSignal and running a Shopify store, you can have data syncing within the hour. Install the Vendo app from the Shopify App Store, connect your OneSignal account, and start building the campaigns your Shopify data has been waiting to power. If you're new to OneSignal, create a free account and explore the platform before connecting your store. And if you have questions about the integration or want help planning your first campaigns, reach out to its team.
