At a glance

  • Turn acquisition and product events into timely onboarding, activation and retention messages.

Who it is useful for

SaaS and subscription teams with reliable events and an owner for messaging operations.

A practical workflow

Define one activation milestone, build a short triggered journey and test entry, exit and suppression rules with known users.

How it fits your stack

Adds behavior-driven lifecycle messaging for SaaS and subscription businesses.

What to consider

Reliable event names, identity mapping and suppression rules need ongoing ownership. Profile and email overages and additional channel services affect cost; the listed entry price is not an all-channel budget.

Pricing and access

Essentials starts at $100/month billed monthly, with 5K people/object profiles and 1M emails/month. Premium starts at $1,000/month billed yearly. A 14-day no-card trial is advertised; overages and channel costs need checking.
