Unique Woocommerece Coupons In Mailchimp

I have a client who wants to offer a unique coupon code for their WooCommerce store when people sign up for their MailChimp newsletter.

I’ve been looking for a way to include a unique coupon code as an auto-responder along with other options but have not found anyting that works well yet.

If I could generate a ton of coupon codes and have them increment by one for each autoresponder that would do.

I found and bought this plugin http://d.pr/12bIT however it has a few bugs and limitations plus since I own Bloom (http://www.elegantthemes.com/plugins/bloom/) I’d love to be able to take advantage of it’s tracking and better design options.

Any suggestions would be great
