1. Go to Marketing > Email > Flows and click + Create Flow.
2. Enter a Flow name (e.g. Welcome Series) and choose the Flow trigger – the customer event that starts it – then Save.
3. The flow builder opens showing the trigger block at the top. Click the + under it to open Add Block and choose Email, Time Delay, SMS, Conditional or List Action. A green Block added successfully! confirms it.
4. Click a block to configure it in the side panel and press Save (Changes successfully saved). Blocks with missing required fields show a warning on the canvas.
5. Keep adding blocks with the + under each block. Use the trash icon on a block to delete it (You are about to delete this block, are sure you want to procede?).
6. When everything is configured, switch the On/Off toggle in the header to On. The flow is now live and will enroll customers as the trigger fires.

Note: once a flow is switched On, the canvas's add-block (+) buttons on empty branches are hidden, so you'll need to switch it back Off to keep adding new blocks.

The trigger cannot be changed after creation – create a new flow instead. Settings lets you rename the flow anytime, or delete it (only when it is Off).
