Emails that send themselves

Welcome new users, follow up on trials and win back customers who leave. Each flow starts on its own, from what happens in your product and in Stripe.

Start a flow from what your users do

A flow starts when an event comes in, when a tag is added or when someone joins a list. Signups come from Supabase, trials and payments from Stripe, and anything else from your app through the API.

  • Built-in events for signups, trials, subscriptions and payments
  • Your own events, sent from your app or your agent
  • Exit rules, so a customer who pays leaves the trial flow
How events work

Waits, conditions and branches

Wait a few hours or a few days, check where someone stands, then send the email that fits. A paying customer gets a customer story, someone still on the free plan gets a hand.

  • Wait steps in minutes, hours or days
  • If and if/else steps on plan, tags, lists or any property
  • Add a tag or a list as a step, to hand someone to another flow

See what each step does

Every step shows how many people reached it and how many opened its email. You see who is waiting, and why anyone got stuck.

  • People reached, opens and clicks per step
  • Who is waiting on each wait step, and when they move on
  • A flow you edit never changes the version people are already in

FAQ

Frequently asked questions

What can start a flow?
An event (a signup, a trial, a payment, or any event your app sends), a tag being added to a contact, or a contact joining a list.
Do I need to write code?
No. Connect Supabase and Stripe and the built-in events arrive on their own. Your own events need one API call from your app, or your AI agent can send them.
What happens to people already in a flow when I edit it?
They finish on the version they started. Your changes apply to the people who enter after you save.
Do automated emails cost more?
No. Every email costs the same, $1 per 1,000, whether a flow or a campaign sends it.
