Every Study supports up to three enrollment modes. They aren't mutually exclusive — turn on any combination, and participants can reach you through whichever channel fits.

Copy the participant link and paste it into an email, message, lab page, or QR code. Anyone with the link can join.
Active Studies show up in the Open Lab participant app. Volunteers find you through search and browse — no prior contact needed.
Upload a list of email addresses. Each recipient gets a unique link tied to their identity — useful for panels, follow-ups, and within-subject designs.
Availability
Run a public listing for general recruitment and send targeted invitations to your panel — both at once. Direct links keep working in the background.
Listings appear when the Study goes Active and disappear when you Pause, Complete, or Archive. Direct links and email invites don't need Active status.
Each recipient gets a unique URL bound to their address. If they share it, the second person can't claim the slot. Best when you need to know exactly who responded.
