What you can build

Sequences

Automated journeys triggered by signups, events, tags, or segments

Campaigns

One-time email and SMS broadcasts to lists and segments

Transactional email

Receipts, password resets, and notifications sent from your app

Subscribers

Contacts with tags, custom attributes, lists, and activity history

Events

Analytics

How it fits together

Your app sends subscribers and events to Sequenzy, directly or through integrations such as Stripe, Clerk, and Supabase. Sequences react to those events, campaigns reach the segments you choose, and transactional email goes out the moment your app asks for it.
