OneSignal plans
| Plan | Price | What it covers |
|---|---|---|
| Free | $0/mo | Unlimited mobile push sends and subscribers; web push capped at 10,000 subscribers per message; 1 active in-app message; 10,000 free email sends/mo. |
| Growth | From $19/mo + usage | $0.012 per mobile monthly active user (unlimited sends), $0.004 per web push subscriber, unlimited in-app messaging; email 20,000 free sends/mo then $1.50 per 1,000. |
| Professional | Custom (annual) | Annual contract with volume-based discounting; adds advanced operational and team features for mid-market. |
| Enterprise | Custom (annual) | Annual contract with volume discounts, 99.9% uptime SLA, and tiered severity-based support response times. |
- Support is the most common complaint, slow, templated, or doc-link responses, especially on free/lower tiers
- Per-MAU pricing 'scales weirdly' and can get expensive as audience grows even without more sends
- 99.9% uptime is only a contractual SLA on the Enterprise (annual) tier, not on free/Growth
