OneSignal vs Postscript FAQ
- Which one is cheaper?
- OneSignal starts lower at $19/mo, compared to $100/mo for Postscript.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.
- Which one is a better deal?
- Depends on what you need. OneSignal: They're the accessible mid-market option in the customer engagement/push notification space — cheaper than Braze or Iterable by a wide margin, but more capable than bare-bones alternatives like Pusher. They're clearly hunting product teams and growth-stage startups who need multi-channel reach without enterprise-level spend. Postscript: Postscript sits in the mid-to-premium range of the SMS marketing space, competitive with Attentive and Klaviyo SMS, and it's clearly chasing DTC/Shopify brands that are already sending enough volume to care about per-message economics. It's not trying to win the hobbyist or ultra-low-volume crowd — the $49 minimum on the 'free' tier filters those out fast.
