Creating an automation for tag based emails post a workshop

We run monthly workshops. Setting up an email reminder campaign is pretty simple, and I’ve managed to do that without trouble. After each workshop, we sort participants into three groups: those who stayed the whole time, those who left early, and those who didn’t attend. We tag each person based on their status.

Each group needs a different follow-up email. On top of that, several internal team members need to get copies of all participant emails, including both the pre-workshop reminders and the post-workshop follow-ups for all three groups.

How can I automate this process? This is what I’ve tried but this does not work as expected.
