Description
The Klaviyo add-on connects User Registration forms to your Klaviyo account, automatically syncing new sign-ups as contacts in the selected list and mapping form fields to profile properties. The integration includes an opt-in option at the time of registration, sends sign-up events, and updates data when the user edits their profile in WordPress.
