Frequently asked questions
What does OneSignal cost for a mid-market app team?
There is a free plan at $0/mo. Growth starts at $19/mo and adds a platform fee plus usage: mobile push at $0.012 per monthly active user, web push at $0.004 per subscriber, and email at $1.50 per 1,000 sends above 20,000 free sends. Professional and Enterprise are annual, custom-priced plans with volume discounts, and SMS/RCS is purchased separately by volume.
How long does implementation take?
OneSignal publishes SDKs for Android, iOS, Flutter, React Native, Expo and Unity, and states that integration can get lifecycle messaging live the same day, so most teams reach first production value within days. Professional and Enterprise tiers add Jump Start onboarding support for more complex rollouts.
Does OneSignal support MCP and external AI assistants?
Yes. The pricing page lists OneSignal MCP on every plan, including Free, and the integrations page includes Claude (Anthropic) and OpenAI (ChatGPT) so teams can manage audiences, campaigns and analytics from those assistants, alongside the OneSignal AI Agent.
What data-protection and compliance commitments are documented?
The pricing page documents GDPR compliance, with a DPA on paid plans, plus two-factor authentication, role-based user permissions and audit-log retention (48 hours on lower plans, 90 days on Enterprise). Enterprise adds a security and compliance package and a custom SLA. Certification details were not published on the pages reviewed.
Can we start free and upgrade later?
Yes. The Free plan includes all channels, basic automation and analytics, and OneSignal AI and MCP. Growth is month-to-month and can be upgraded in the dashboard, while Professional and Enterprise are annual contracts with volume-based pricing, payable by card, wire or ACH on annual plans, or through the GCP Marketplace.
