A cohort is a named set of your event’s attendees: VIP guests, Speakers, Everyone still pending. You build it once on the Cohorts page, then apply it wherever a recipient selection is needed — an email send draft today, and automations can add people to one or branch on membership.

Create a cohort

1

Name it

Click Create cohort and give it a name. Members are picked on its page.
2

Choose how membership is maintained

  • Static — you maintain the members; the set changes only when you change it.
  • Dynamic — rules maintain the members; attendees who start or stop matching move in and out automatically.

Fill it

A static cohort’s members come from picking from attendees — filter or search the table and tick people in — or from freezing the current result of rules as a one-time snapshot. A dynamic cohort just keeps its rules; the member list is whoever matches right now.
You can also create a static cohort without visiting this page: on any email send draft, tick your recipients and click Save as cohort.

Rules

Rules are conditions combined with a match mode — match all conditions (intersection) or match any condition. Each condition tests one fact about a registration: With no conditions, the rules match every attendee — add conditions to narrow. A live Preview shows how many attendees match right now, and every condition needs a value before the cohort can be saved.

Static vs. dynamic

A dynamic cohort applied to a send draft brings in its current members at that moment; the send then records exactly who was addressed.

Rules to know

  • Cohorts are per event and live under the event’s Marketing group.
  • Membership resolves against the live attendee list when applied — registrations that no longer exist drop out automatically.
  • A snapshot does not follow its rules. Freezing the result of rules into a static cohort keeps those people even as the facts change; use a dynamic cohort if you want the set to track reality.
  • Automations can only add people to a static cohort — a dynamic one derives its own members and cannot be added to by hand or by flow.
  • Deleting a cohort is allowed and does not touch anything sent with it: send records keep their own recipient lists.
