I currently have several engagement programs running where a person who fills out a specific form on our website will be entered into a specific engagement program and receive a specific series of emails over time.
If the same person happens to fill out more than one form, I'd like to exclude them from entering any additional engagement programs and only receive emails from the first one. What is the correct smart list filter logic to use for each program?
For the filter above, is this saying that the lead will be included in this engagement program if they are not a member of any other engagement program?
Should I use this and list all of the other active engagement programs other than this one?
