Follow-up after the event is critical. Compare the list of registered attendees versus those who actually attended. Gather their contact information so you can send out surveys and receive feedback, if desired. The key is to get your follow-up emails out as soon as possible after the event, as well as any information you promised to deliver to your audience via email. A prompt follow-up means your webinar is still fresh in your audience’s mind and the feedback will be more valuable. Within an hour is the best amount of time.
