New Platform Acquisition ( FINTECH experience Required)

Output :
3 acquisition driven emails with auto responder & 2 product write up.
-email is to introduce the platform to prospect companies via database email marketing to get their attention on the platform features and get them to request for a demo.
-articles, I probably do a Linkedin post for the time being and send to a fintech news website for them to publish on their page

Brief platform Background ( Details Will be given when project starts) :
The platform is created for traditional financing companies with no digital capability. The platform enables them to immediately convert their business process into a digital environment. It covers product design, customer acquisition, application processing and assessment up to disbursement.

The platform features are plenty, but I need someone who has tech & financial copywriting background to help identify the key USP to be featured in the series of emails.

Do include any similar copywriting you have done to help us decide.
