How it works

From zero to first campaign in minutes

Four steps. That's all it takes to start engaging your customers on every channel.

01

Connect your data

Import contacts, sync attributes, and start ingesting behavioral events from your product with a single API call.

POST /api/v1/events
{ "event_name": "purchase",
  "properties": { "amount": 99.00 } }
02

Build your audience

Create segments that combine contact properties with event history. "Users who signed up this week AND viewed pricing 3+ times."
