A: Webinar with event registration is a feature that allows hosts to collect participant details before the webinar through a registration process. This is particularly useful for tracking attendance, sending reminders, and managing follow-up communication. The event registration feature adds a professional layer of engagement, especially for larger or formal events, and is available as an add-on on higher-tier plans, such as the Pro plan (Tier 7).

In contrast, free webinar mode refers to the basic webinar functionality included with all plans. Participants can join directly without needing to register in advance. However, this mode lacks advanced features like attendee tracking and automated reminders. Additionally, the number of participants is limited based on the tier of your plan. For instance, with a Tier 1 (basic) plan, you can host up to 12 participants, while Tier 7 allows up to 300 participants. On the other hand, if you opt for the event registration feature available with the Pro plan, you can increase the participant limit to as many as 10,000, depending on the add-on you purchase​.
