Everything you need.
Already built-in

Drop-In Designer

Drop a message editor directly into your app. Let your users design and send their own notifications without building the infrastructure yourself.

API Integrations

Native support for 50+ email, SMS, push, and collaboration tools. Connect to SendGrid, Twilio, Firebase, Slack, and more without writing custom code or managing webhook endpoints.

Multitenancy

Run separate notification environments for different teams, brands, or customers without rebuilding your stack. Each tenant gets its own rules, templates, and data.

Omnichannel Analytics

Track delivery rates, open rates, and click-through across every channel. See what's working and what's not without stitching together five different dashboards.

Preference Center

Let users control what notifications they receive and how. Embed preference centers and notification centers that respect choice instead of forcing blanket unsubscribes.

Multi-Channel Routing

Send messages on the right channel (email, SMS, push, and more) based on user preferences and delivery rules—without building routing logic yourself.

from fast growing startups to the Fortune 500
