Send a signing request to all members who haven't signed yet. Works for both the main studio waiver and per-class waivers.
Go to Forms & Waivers → Waivers tab. You'll see a list showing who has signed and who hasn't.
This sends an email with a signing link to every member who hasn't signed yet for your primary studio waiver.
When you have more than one active waiver (e.g. main waiver + Aerial Yoga), a "Send a specific waiver to members" panel appears above. Pick the template, click "Send re-sign requests", and Klasly emails every active member who hasn't signed THAT waiver — others are skipped automatically.
