How to Turn a Flow Live
To start sending a flow, click on the Flows tab and then on the name of the flow in the list.
For each email in the flow you want to start sending, make sure you've customized and previewed the content. Once you've reviewed the email content, click on the paper airplane icon to the left of the flow email name and change the status to Live.
This will start sending emails automatically for any queued recipients. This won't affect anyone who might have received the emails in this flow in the past.
If this email's status was manual and there are any recipients awaiting review, those recipients will still need to be reviewed and sent manually. Emails marked for manual review are not sent automatically when an email's status changes.
