A registrant completes an online registration form for an event that is set up to automatically send email confirmation messages.
The registration contact, housing manager, and/or travel manager can elect to receive an email copy of any attendees who online and complete their registration, housing request, or travel request, respectively.
The planner can send an individual message to a single profile or registration.
The planner can send a message to a group of profiles or registrations.

Email messages can be saved and re-used for future message batches or events.

Sending a Message to a Group of Registrations

In order to send a message to a group of profiles or registrations, the planner must first assemble the group.

This assembly can be done by running a report or searching for registrations.

Running a report with a delivery method of the Results window or Formatted HTML.
Searching for registrations (Registrations > Query Registrations).

After the search returns a results set, click Compose Email in order to create a message. After typing and formatting the email, send it to the group. If a pre-defined Email template is available, the planner can use a pre-defined Email template as the basis for the email if one has been pre-configured as part of the event.
