The ConvertKit addon connects WPForms forms to your ConvertKit account, automatically sending each submission as a new subscriber and assigning tags, sequences, or specific forms according to the filled field. Designed for those who capture leads, newsletter signups, and registrations on sales pages, the component eliminates manual CSV export and keeps the email database synchronized in real time after each form submission.
