Add new Responders or correct email address errors on the PEOPLE tab.
If new people have been added or addresses corrected after the project launch date, re-schedule your original Catalyst email by updating the send date to a future date. The re-scheduled email will only be sent to new addresses—i.e., those who haven't received this email before.
Note: Re-schedule your original Catalyst email—do not create a new email if you only intend to send it to new or updated addresses, as a new email will be sent to all participants in the project.
