An extremely useful feature you can take advantage of from within Single after publishing your membership is to export a full list of active members. This export can either be of the entire membership, which includes every tier (click the “Export Members” button on the main page of the membership)...
…or of an individual membership tier (click on the desired tier from the main page of the membership and then click “Export Tier Memberships”).
This export will be in the form of a .csv file that is sent directly to the email address you are logged into your Single account with. The export will provide you with customer info such as email, name, membership/tier/term, and location, as you can see in the example below.
