Add function for mail

I’m creating a web page on localhost where customers fill in a form and I get my email.

I use the Cfroms plugin and I have been programmed into a PHP file so that the forms that are made reach my mail in .CSV file

But since I do not have such advanced knowledge, I can not make the forms reach my email in CSV format.

Could you help me?
