Send web and mobile app push notifications that bring users back with updates and offers.
Push notification software can target mobile apps, web browsers or both, and that distinction should be checked before anything else. Beyond channel coverage, buyers should compare SDK requirements, journey automation, deep links, rich content, segmentation and how delivery or engagement events flow back into customer profiles. Some products are broader lifecycle-marketing platforms; others make push the center of a multi-channel messaging service. The five tools here are grouped by push use case and are not ranked on a single feature list.

Ecommerce mobile push
#1 of 5 in Push Notifications
Klaviyo supports mobile push notifications that can be sent through campaigns and flows, letting ecommerce marketers coordinate app messages with customer data already used for email and SMS. The fit is strongest for brands using Klaviyo as the central lifecycle-marketing system around an owned mobile app. Its mobile setup uses platform-specific app credentials and Klaviyo SDKs, and notifications can deep-link customers back into app experiences.
For mobile and web push
#2 of 5 in Push Notifications
OneSignal supports mobile and web push notifications and connects them to Journeys, audience segmentation and other messaging channels. Teams can build automated paths that respond to user behavior, then use push alongside in-app, email or SMS messages when appropriate; its broad push coverage makes it particularly useful when a product needs both app notifications and browser notifications under one engagement workflow.
For deeply integrated app messaging
#3 of 5 in Push Notifications
Braze supports push notifications as part of its customer-engagement platform and provides SDK-level controls for web and mobile implementations. Its developer documentation covers service workers, permission handling, click behavior and push-event callbacks, while campaign orchestration can place push inside broader customer journeys. This suits product organizations that want detailed implementation control and cross-channel lifecycle messaging around the same user profile.
Event-driven mobile journeys
#4 of 5 in Push Notifications
Customer.io lets teams place push notifications inside automated Journeys triggered by events, segments, dates, forms or webhooks. Choose it when push should react to behavioral data and coordinate with email, in-app, SMS or other lifecycle messages. Its mobile push supports images, links, sounds, deep links, localization and custom payloads, with SDKs for common mobile frameworks.
Mobile and web journeys
#5 of 5 in Push Notifications
Iterable supports push campaigns for mobile apps and also documents web-push setup, alongside its wider cross-channel journey capabilities. Mobile SDKs help capture device tokens, handle rich notifications, deep links and engagement events, while silent push can trigger background app behavior; the platform fits lifecycle programs where push is coordinated with other campaign channels and where engineering teams can support the required app or web integration.

Mobile push is sent to an installed app through mobile push services, while web push is delivered through a browser subscription and can appear without a native app. A vendor may support one and not the other. Klaviyo, for example, documents mobile push but states that native web push is not currently supported.
The messaging service needs a way to register devices or browsers, receive push tokens, handle clicks and report engagement events. Mobile SDKs and web service workers provide that connection. The marketing workflow may be no-code after setup, but engineering work is normally required to establish the delivery and tracking layer correctly.
Yes, Klaviyo and OneSignal both offer a free plan. Free tiers usually come with usage limits, so check whether they cover your volume before relying on them long-term.
