How Argon works

Collect, decide, deliver

You can trace every message Argon sends back to the event and the rule that sent it.

  • Collect

    Send events from your app with our API and SDKs. Or sync people and traits from Snowflake on a schedule.

  • Decide

    Build segments from any event or trait. Then draw journeys with waits, branches, goals and exit rules.

  • Deliver

    Send email, SMS and push from one place. We handle authentication, warm-up and suppression lists.

For developers

Start a journey with one API call

Send one track call. Argon updates the person’s profile, rechecks their segments and starts any journey waiting on that event.

  • Retry safely: a repeated event ID never sends a message twice
  • Separate test and live workspaces
Read the docs
await argon.track({
  userId: "usr_2041",
  event: "trial_started",
  properties: { plan: "growth" },
});

Why Argon

Named for a noble gas

Argon is element 18, a noble gas. It’s stable and rarely reacts. We think messaging should work the same way: dependable, and sent only when a customer does something.
