Case study - Reminder of a passing webinar


Aim of campaign

Increase people attendance to webinar.



There's a customer database in our CRM system, who have submitted an application for participation in a free webinar. The sales funnel looks like this: Application -> confirmation of participation -> webinar. Since the participants database is stored in CRM, we connected the Callisto widget. We customized the call script and selected those who left the application for participation in the webinar.



By clicking on the number "1" we move the card to the stage "participant" for further sale to this customer.
