Hi @chawk57
I have made a test for your reference:

2.

Name:
trim(replace(first(split(replace(outputs('Html_to_text')?['body'],decodeUriComponent('%0A'),''),'Email')),'Name:',''))
Email:
trim(first(split(last(split(replace(outputs('Html_to_text')?['body'],decodeUriComponent('%0A'),''),'Email:')),'Phone:')))
Phone:
trim(first(split(last(split(replace(outputs('Html_to_text')?['body'],decodeUriComponent('%0A'),''),'Phone:')),'Comments:')))
Comments:
trim(last(split(replace(outputs('Html_to_text')?['body'],decodeUriComponent('%0A'),''),'Comments:')))
