Body: <p>As part of my online events, all participants should receive various mailings throughout the event.
  The problem is that I have people who keep registering to the event, and then they should receive the emails that the others had already received so far.
  How can I re-send a mailing to all participants of an event, excluding all the participants who had already received that mailing in the past?</p>

  When composing your mailing use the "Recipients" field to exclude recipients of one or more past mailings. Here's a screenshot of this in action:

  Specifically, you would choose one group to *include* (which can be a [smart group](https://docs.civicrm.org/user/en/latest/organising-your-data/smart-groups/) based on the event), and several *mailings* to exclude.
