This is an welcome email sequence. It is a series of emails that a business send to a prospective customer who has shared his/her email id for a free valuable resource. 

The welcome email sequence helps the business owner provide the resource to the prospect, introduce themselves to the customer, thank them for joining the community and sell a high priced product or service. 

In this pow, it is a 5 email series. The prospect has signed for a short prerecorded masterclass on freelancing. First mail delivers the masterclass and rest of the mails builds relationship and offers help through a paid mentorship in the form of a high priced freelancing course.
