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 with 1,000 free emailsStart 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
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
