How Can I Automatically Read Email Body and Write into Leads

Hello Friends,

I am trying to get this right, how can I automate reading email and assigning content to lead fields.

I have activated reading the title and sender to create documents, works fine.

But I want to be able to read content which comes as a predefined format.

Please help, it has been frustrating for weeks now.

Anyone with pointers, I would be glad.

Inbtw, ERPNEXT is awesome.
