Auto-generate and email coupon codes using Woocommerce

Hi,
My website has a sign up form where visitors can put in their name, email and phone number to sign up.
I need a feature where, as soon as the visitor signs up, an email is sent to his/her email address containing a unique coupon code. This code can then be used on the user’s next order.

The coupon needs to:
– Have a unique code
– Usable only once
– Be subject to certain cart conditions such as minimum order
– Have an expiry specified number of days from sign up (for example, 7 days from sign up)

Currently Woocommerce does not seem to have an automatically-email on sign up feature I believe. Any free or paid plugins that can do this?
