OneSignal review

OneSignal is a lifecycle messaging platform for teams that want to coordinate customer communications across push, email, SMS/RCS and in-app messages. Its core pitch is broader than sending notifications: Lifecycle Journeys can orchestrate campaigns for onboarding, engagement and retention, while personalization and analytics help teams tailor messages and assess outcomes.

The platform also offers AI-assisted campaign work. OneSignal says AI can draft, send, test and optimize campaigns within brand guardrails. The published feature information does not specify which plans include those AI capabilities or how usage is limited, so confirm that before budgeting around them.

For mobile development, OneSignal lists SDKs for Android, iOS, Flutter, React Native, Expo and Unity. It also connects messaging with analytics and customer data tools, though the published information does not name those integrations. In practice, this makes OneSignal a candidate for teams that want marketing workflows and developer-facing delivery tools in one product—not just a push service.

The clearest advantage is channel and workflow coverage. OneSignal brings push, email, SMS/RCS and in-app messaging together with lifecycle journeys, segmentation, personalization and analytics. That can reduce the number of tools a team needs to coordinate, especially when marketing staff need to run campaigns without routing every change through app code. One Reddit commenter made a similar distinction, saying OneSignal may suit teams that want push, email and automation in one place; that is one user’s view, not a guarantee of fit.

The entry plans have concrete limits, which makes an initial cost check possible. The Free plan includes 10,000 email sends a month, mobile push and in-app messaging for up to 1,000 monthly active users (MAU), web push for up to 10,000 subscribers per send, and three active journeys. Growth starts at $19 a month and includes 20,000 email sends, five active journeys, 10 audience segments and 30-day message-event retention.

The listed SDK coverage is also useful for teams building across native and cross-platform mobile stacks: Android, iOS, Flutter, React Native, Expo and Unity are named. OneSignal’s pricing page lists unlimited sends for Growth mobile and web push, though those channels are charged by MAU and subscriber count respectively.

The free tier is not a generous fit for a growing app if mobile usage is the main constraint: it stops at 1,000 MAU for mobile push and in-app messaging. A Reddit thread describes that same 10,000-to-1,000 MAU reduction as a reason to look elsewhere. Growth removes that stated cap from the included feature list, but mobile push then costs $0.012 per MAU; web push costs $0.004 per subscriber. Growth email is $1.50 per 1,000 sends after the included 20,000 monthly sends.

SMS/RCS pricing is not published, so teams cannot estimate a full multichannel bill from the published pricing information. Professional and Enterprise also require annual contracts with custom pricing. Professional lists 20 active journeys, 20 audience segments, 100 data tags and one year of reporting history; Enterprise lists unlimited journeys, segments and tags, with two years of reporting history. Message-event retention is 90 days on Enterprise, compared with 30 days on Growth.

Support is another point to check before switching. One Reddit commenter reports slow responses and ignored issues, while another thread complains about pricing changes. Those are individual reports, not verified service-wide findings, but they argue for confirming support terms and migration costs before committing.

OneSignal has a free plan, and Growth starts at $19 per month. The Free plan includes 10,000 email sends a month, mobile push and in-app messaging for up to 1,000 monthly active users (MAU), web push for up to 10,000 subscribers per send, and three active journeys.

Growth is month-to-month. It includes 20,000 free email sends a month, five active journeys, 10 audience segments, and 30-day message event retention. The pricing page lists extra Growth email at $1.50 per 1,000 sends, mobile push at $0.012 per MAU, and web push at $0.004 per subscriber. Push sends are unlimited on those paid add-ons.

The next tier is a contract change, not a listed price step: Professional and Enterprise require annual contracts with custom pricing. Professional includes 20 journeys and one-year reporting history; Enterprise adds unlimited journeys and two-year reporting history. SMS/RCS and premium integration prices aren’t published. Webhooks are available on annual plans, with pricing by sales. A free trial isn’t listed.

OneSignal covers push, email, SMS/RCS and in-app messaging, with SDKs listed for Android, iOS, Flutter, React Native, Expo and Unity. That breadth may make a move involve more than replacing a sending tool: map your channels, journeys, audience segments, event data and app integrations before deciding what needs to migrate. The published materials don’t document migration services, import formats, data export options or how existing journey logic transfers, so treat those as questions for sales or support—not assumed capabilities.

We also don’t have sourced Reddit posts in this brief, so we can’t responsibly say what users most often cite when leaving OneSignal. Before committing, ask how to export subscribers, consent records, message history and analytics, and whether exports include the fields your next platform needs. Check SMS/RCS rates separately; they aren’t published. If leaving, confirm export access and timing before ending service, especially if you rely on annual Professional or Enterprise terms. The available pricing details don’t specify cancellation or renewal rules.
