OneSignal handles push notifications but requires SendGrid for email and Twilio for SMS. Intempt delivers push, email, SMS, and in-app messaging from one platform starting at $19/seat/mo.

Why marketing teams are leaving OneSignal
Real complaints from real users, pulled from review platforms, community forums, and customer migration calls.
OneSignal is primarily a push notification tool. For email you need SendGrid. For SMS you need Twilio. Running all three costs $200 to $600 per month before a single campaign goes live.
There is no unified customer profile. Push subscribers in OneSignal, email contacts in SendGrid, and phone numbers in Twilio are three separate lists with no automated sync.
Journey orchestration requires stitching OneSignal, your ESP, and your SMS provider together through Zapier or custom code. engineering overhead for a marketing task.
Analytics are siloed per channel. You cannot see email open rates, push click rates, and SMS conversion in one report or attribute revenue across the full customer journey.
OneSignal's free plan has a 10,000 subscriber cap and no multi-channel orchestration. Scaling past it triggers per-notification pricing that becomes unpredictable.
There is no experimentation layer, no on-site personalization, and no product recommendation engine built in, all requiring additional tools and contracts.

What makes Intempt different
Not just a replacement. A platform built differently from the ground up.
Experiments across every channel
OneSignal A/B tests push messages only. Intempt tests email, SMS, push, in-app, and full-site web variants, all measured against the same unified customer profiles.
Cross-channel revenue attribution
OneSignal shows push click rates. Intempt shows which combination of channels drove conversion. Funnel, retention, and revenue analytics built into the same platform.
Blu orchestrates the full journey
AI-drafted cadences, behavioral triggers, and personalized copy across every channel, replacing the manual overhead of coordinating three separate messaging platforms.
What our customers have to say
“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.”
