A real CDP, revenue analytics, web experimentation, and product recommendations; connected to the same unified profile. Free to start, or from $18/seat/mo.
Why teams leave
Real complaints from real users, pulled from review platforms, community forums, and customer migration calls.
Push subscribers, email contacts, and phone numbers in OneSignal are separate lists per channel with no true CDP tying them together. There is no unified profile connecting product activity, purchase behaviour, and messaging data in one place.
OneSignal shows push click rates, email open rates, and SMS delivery metrics separately. You cannot see the full customer journey in one report or attribute revenue across channels to understand what's actually driving conversion.
There is no web A/B testing, no on-site personalization, and no product recommendation engine in OneSignal. Every one of these capabilities requires a separate tool, a separate contract, and a manual data sync.
An honest, feature-by-feature comparison to help you make an informed decision.
Blu AI
OneSignal AI is an MCP server that lets external AI assistants control OneSignal via API, currently in open beta and requiring a separate access request. Blu is native to Intempt; it analyses your customer data, builds segments, drafts copy, and triggers journeys without any external tool or API integration.
OneSignal requires you to build the journey, write the copy, and configure the trigger before anything sends. Blu drafts campaign copy, builds audience segments from live product data, and personalises experiences across every channel, with no manual creative overhead.
OneSignal sends messages you configure. Blu detects what's happening in your product and responds. When a user hits an activation event, visits pricing three times, or goes quiet for 14 days, Blu identifies it from the unified profile and triggers the right response automatically.
Most teams are fully migrated and live within a week.
01
We audit your push subscriber list, email contacts, and SMS numbers to plan the migration path for each channel separately, with no overlap or subscriber loss.
02
One Intempt SDK replaces your OneSignal, SendGrid, and Twilio SDKs. Configure push, email, and SMS in one dashboard with no multi-tool coordination required.
03
Send from both platforms for one campaign cycle to validate deliverability and click rates. Cut the old tools on a confirmed date with IntemptVIP on call for 90 days.
Replace OneSignal, SendGrid, and Twilio for less than the cost of running all three separately.

“We were losing visitors before they signed up. Intempt's personalized experiences changed that - we started meeting people where they were instead of guessing. Once they're in, Intempt's automated email takes over and keeps the relationship moving. Acquisition and retention finally feel like one connected motion instead of two separate problems.”

Case Study
StockInvest needed to turn anonymous traffic into registered users before any retention strategy could work. With Intempt's Experiences, they personalized the anonymous visitor flow, surfacing the right content and CTAs to boost signup conversion. Once users signed up, automated Journeys nurtured them through onboarding and deeper engagement, steadily increasing lifetime value.
Yes. Intempt includes web push and mobile push as native channels. You install one SDK, and push notifications are available alongside email, SMS, and in-app messaging in the same journey builder. No separate OneSignal subscription.
Push subscriber tokens can be migrated or re-collected via Intempt's web SDK. For most teams, the fastest path is to install Intempt's SDK alongside OneSignal, collect new subscribers, and cut over when the list is rebuilt.
OneSignal's journey builder is limited to push notifications. Intempt's journey builder spans email, SMS, push, and in-app messages in a single flow. One condition logic tree routes customers to the right channel based on preference, availability, and engagement.
Yes. Intempt lets you A/B test messages within a journey across all channels — email, SMS, push, and in-app. You can also run full-site web experiments and personalization tests. OneSignal only supports A/B testing for push messages.
A typical stack with OneSignal paid ($9+/mo), SendGrid Essentials ($19.95+/mo), and Twilio SMS ($25+/mo plus per-message fees) runs $60 to $200 per month before scaling. Intempt's Professional plan starts at $18/seat/mo for unlimited messaging across all channels.
OneSignal's SDK installs in minutes for push. Intempt's single SDK installs in under 30 minutes and enables push, email, in-app, and event tracking in one step. Most teams have their first multi-channel journey live within a week.
