New User Registration Confirmation Email

I’ve done quite a bit of research on this topic, but can’t find a general plugin for this. Everything i’ve found is either too advanced, or you have to purchase a license.

I just want a confirmation email to be sent to a new user after they register on my blog. Seems pretty simple, but it’s proving to be a difficult issue.

I’ve tried WP-Members, but it requires the use of fields. I’ve already got a registration form styled out. I don’t want to use any of it’s fields, but it won’t work unless i do. Frustrating.

Thank you for any help and guidance in the right direction.
