In order to take part in a webinar, participants must register in advance with their name and email address. This is the only way interested parties will receive the participation link. You can use this registration to contact you further, but we recommend the following when handling this data.

Offer participants the opportunity to sign up for your newsletter or blog subscription during the seminar and encourage them to ask questions and interact.
Send the recording of the webinar to the participants so rich people database that they can watch it again at their leisure. You can offer your personal contact details here.
Regularly provide your new leads with relevant, valuable content.
Let your new leads come to you – if the webinar and the subsequent content have excited them and aroused their curiosity, they will take the next step.
conversions
Offer in-depth or advanced webinars on topics related to your product or service. This way, potential customers can educate themselves on their own and see the benefits of your offer. Webinars that build on one another also help to build a relationship through direct contact. Webinars accompany your customers along the customer journey.
