Step 1: Create an Autogroup:
In order to identify the recipients for your email, you can add your users to an autogroup (for more information on how to use autogroups and filtering in ARI see this article: https://intercom.help/arirecruiting/en/articles/4879385-how-to-use-auto-groups-filters). The filters on that group will determine who receives your email.
Tip: If you would like to create a hand picked auto group for mass emailing purposes, you can create a tag and add that to each record you'd like to include in the group.
Step 2: Add the Group to the Recipients Field in a Mass Email
Navigate to the ARI messenger and select "Mass Emails", then click mass email.
Click the "choose recipients" button
Select the "Groups" tab and then indicate the subgroup ("Athletes", "Parent 1", Parent 2" etc.)
