Everything you need to know about pricing and plans
A MAU is any unique subscriber who triggers at least one workflow or receives a notification in a calendar month. Inactive users don't count toward your limit.
An event is any subscriber action tracked through our SDK (e.g., trial.started, payment.failed, subscription.cancelled). Events are only counted once, even if they trigger multiple workflows.
Trial activation, trial expiring, payment failed, payment recovered, subscription cancelled, winback, upgrade prompts, downgrade prevention, onboarding, engagement, renewal reminder, and annual upsell. All activate in one click.
Free includes email only. Startup adds push notifications. Growth adds SMS. Enterprise includes WhatsApp and custom channels. You provide your own SendGrid/Twilio credentials.
Yes! Bring your own SendGrid, Resend, Twilio, or other provider credentials. We integrate with them. You only pay us for the platform, not per message.
Our AI writes copy variations for your messages and uses Thompson Sampling to automatically route traffic to winning variants. It also optimizes send times based on subscriber engagement patterns.
