Filtering who enters a flow better

There are multiple ways of doing it by setting certain contact properties and/or passing in more information with your forms, but with a very general, blanket statement, you could always just set a Flow Filter for “has not been in this flow.”

Hi @eck thank you for this question.

And thank you @In the Inbox and @DavidSandel for your helpful insights. @In the Inbox is spot on with his note on users only being able to travel through a list-triggered flow once. 

You may also want to investigate a potential duplicate welcome flow in your account that’s triggered off of the same list, making it appear that a user has gone through the same welcome flow twice (when in reality they’ve actually gone through two separate flows triggered off of the same list). It’s unlikely (unless you’ve explicitly cloned your existing welcome series) but worth looking into anyway :)

One little trick you can use to differentiate between flow email sends, is to click on this little icon on user profile page next to the “Received Email” metric. That will lead you directly to the flow the email was sent from.

I’d also double-check the lists the sign-up forms submit to as well. It’s also possible one sign-up form is sending emails to another list-triggered flow. You can double-check the list connected to each sign-up form in the Signup Forms tab. 

I hope that additional insight is helpful :)
