What does OneSignal cost?

The Free plan costs nothing and covers every channel, with 10,000 email sends a month and unlimited mobile push for up to 1,000 monthly active users. Growth starts at $19 a month as a platform fee, with messaging metered on top at $0.012 per monthly active user for mobile push, $0.004 per web push subscriber and $1.50 per 1,000 email sends beyond the first 20,000. Professional and Enterprise are annual contracts priced on quote with volume discounts.

Which channels does OneSignal cover?

Email, mobile push, web push, in-app messaging, SMS and RCS, plus iOS Live Activities. All of them are available on the free plan, and SMS and RCS are purchasable with volume-based discounting.

Can an AI assistant operate OneSignal?

Yes. OneSignal AI works inside the dashboard, answering questions about campaign performance and creating segments, templates and workflows from plain language. Separately, a hosted MCP server in open beta connects an outside assistant such as Claude, ChatGPT, Cursor or GitHub Copilot to the messaging, user, segment, template, export and analytics endpoints.

Overview

OneSignal is a customer engagement platform that sends email, mobile and web push notifications, in-app messages, SMS and RCS, and iOS Live Activities from one dashboard. Messages are built in a no-code or HTML builder with Liquid syntax for dynamic content, then orchestrated through Journeys, a drag-and-drop workflow builder. Audiences are described with data tags, segments and custom events, and delivery runs through SDKs for the major mobile frameworks next to an API send endpoint. Pricing is a platform fee plus metered usage rather than a per-seat licence.

Our take

OneSignal fits product and growth teams whose messaging begins in an app rather than an inbox, and its free plan is unusually generous for a platform of this reach, so a small team can run real lifecycle campaigns before paying anything. The pricing model is what to check before committing: cost follows monthly active users and send volume instead of a flat seat fee, so a consumer app with a large but lightly engaged audience can end up paying more here than on a contact-based plan, while a team with a small, valuable audience pays very little. Read the plan ladder carefully too, because the ceilings arrive lower than the channel list suggests. A team whose programme is mostly email should pick a dedicated email platform instead.

Pros and Cons

Strengths

The free plan carries every channel, including unlimited mobile push for up to 1,000 monthly active users
Unlimited contacts and unlimited API send access on every plan, the free one included
Push, in-app, email, SMS and RCS run on one platform, so a lifecycle programme does not span two vendors
Official SDKs for Android, iOS, Flutter, React Native, Expo and Unity
A hosted MCP server lets an outside AI assistant query analytics and operate campaigns

Limitations

Active journeys, audience segments and data tags are all capped below the Enterprise plan
Frequency capping, conversion metrics and CSV exports start on the annual Professional plan
Cost follows monthly active users and send volume, so a large but lightly engaged audience gets expensive
Dedicated sending IPs are limited to the annual plans and depend on volume
Professional and Enterprise pricing is quoted rather than published
