I'm using a sign up form on my client's website, and it seems to work
okay, but no one is being added to the audience group. In the past, we
used to call this purgatory. Can you help me find where people are going?
There are a few things we can check. One would be to see if there is a group assigned to the signup form from within Emma. You can check this by going to audience > forms > signup. From here ensure the 'add to groups' section to the right of your signup form fields has a group selected.
You can see if contacts are floating without a group (we refer to this as a 'Limbo' segment) by going to audience > segments > create a new segment > find contacts based on audience groups > not in any group. Also see our resource center article here on that:
