emails for customers | WordPress.org

Hi all,

I am new to WordPress, Mollie and pretty much everything related to websites, so my question could be very basic : )

I am trying to configure a Mollie form to send emails to both the Customer: payment successful and Merchant: payment successful. I am learning about variable names, such as {rfmp= “Name”}. To configure the email for the customer, I have filled the following

Subject: A subject

From “email”: [email protected]

From “name”: my_name

I am not using any variable name or fancy format. Is this correct? the customers are not receiving any email after payment
