My question is about the email a person gets after signing up to a subscription

Hi, I just purchased Membership Plugin and So once a person signs up for a subscription they get this email let in them know there username and password BUT the email says is from WordPress (wordpress@iconnectjobs.ca). Why? I would like it to have the email that I choose it to be....Please help. AND a personalized message. I need to be able to edit our own email.

Thank you!
