Event planning should always include a follow up plan. How are you following up with your visitors.
Your Church service should be no different. How are you following up with your first time guests? How are you tracking the effectiveness of your follow up?
Nearly all church management software programs will include fields for ‘membership type’ (or similar wording). Many offer automated process queues or follow-up alerts.
Use those features and allow them to help you better see where each person is in the process.
