OneSignal sends push notifications.That is about it
You still need SendGrid for email, Twilio for SMS, and Mixpanel for analytics. Intempt puts all four in one system with AI agents and real customer profiles. Billed per seat.
Why teams leave
Why marketing teams are leaving OneSignal
Real complaints from real users, pulled from review platforms, community forums, and customer migration calls.
OneSignal charges per mobile MAU on the Growth plan, so the push bill tracks how many people opened the app. And MAU means monthly active user, not subscriber - you pay for users who never opted in to push.
OneSignal does push and basic email. For SMS you need Twilio. For marketing email you need SendGrid or Mailchimp. For analytics you need Mixpanel. Four tools, four bills, four dashboards, no shared customer profile.
OneSignal segments are tag-based. No behavioral events, no identity resolution, no computed traits. You cannot build an audience like "users who viewed pricing 3+ times but did not start a trial" without piping data from another tool.

What Blu does that OneSignal can't
Lifecycle Marketer

OneSignal journeys are push-first and limited to Professional (custom pricing). Lifecycle Marketer orchestrates all channels from day one on any plan.
Data Analyst
Ties messaging to revenue and conversion

Switching from OneSignal is easier than you think
Most teams are fully migrated and live within a week.
01
Connect your app and import subscribers
Install the Intempt SDK alongside OneSignal. Import your subscriber lists and tags. Both SDKs can run in parallel during migration.
02
Rebuild your push campaigns and add channels
Recreate your active push campaigns in Intempt. Add email, SMS, and in-app to the same journeys. Most teams are sending from Intempt within a week.
03
Remove OneSignal SDK after validation
Monitor delivery rates and opt-in rates for two weeks. Once metrics match, remove the OneSignal SDK and cancel your plan.
An honest read on OneSignal
Where it is strong, where it is not, and who should pick it over us.
What OneSignal does well
- The fastest push implementation in the category, on every platform
- A free tier that is genuinely usable rather than a trial
- Reliable delivery at very high volume across iOS, Android and web
- In-app messaging and simple journeys cover the basics without extra tooling
Where it falls short
- Growth bills per mobile monthly active user, so the push bill tracks app usage and not push usage
- MAU counts people who never opted in to push at all
- Email, SMS and analytics mean SendGrid, Twilio and a product analytics tool alongside it
- It does not resolve identity or attribute revenue, so push sits outside the rest of the funnel
Who uses OneSignal
Mobile app teams whose only channel is push · Startups on the free tier validating whether push moves anything · Developers who want push working in an afternoon
Pick OneSignal if
Push is the only channel you need, you are inside the free tier, and there is no plan to add email, SMS or analytics. OneSignal will get you there faster than we will and cost nothing while it does.
Bottom line
The best OneSignal alternative for teams who have outgrown push as a standalone channel and need it in the same journey as email and SMS. For push alone, OneSignal is hard to beat.
Active users are not the meter.
OneSignal prices per monthly active user, so an audience that never opens a push still bills. Intempt is on-demand. Metered products bill monthly in arrears on actual consumption, with no prepaid bundle to waste and no overage surcharge, rates fall as volume rises, and a month you do not use a product is a month you are not billed for it.
Per monthly active user
- A user who never opens a push is still on the meter
- Email and SMS are separate products with separate billing
- Audience size sets the bill, not messages delivered
On-demand, billed in arrears
- Metered products bill on actual consumption, monthly in arrears
- No prepaid bundle to waste and no overage surcharge
- Rates fall as volume rises, with nothing to renegotiate
- A month you do not use a product is a month you are not billed for it

Frequently askedquestions.
- Yes. Both use FCM and APNs for mobile delivery. Push reliability depends on the device OS, not the platform.
