Woocommerce plugin that will notify me and the customer (or send them a voucher) once they have purchased £x amount from a particular category

Does anybody know of a plugin for woocommerce that will send a voucher (e.g. get a free product on your next order) but only after they have spent a cetain amount within a certain timeframe from a certain category - this can be over multiple orders.

Example: spend £50 on shoes before christmas and we’ll send you a voucher for free socks!
Dec 5: £15 on shoes spent
Dec 10: £25 on shoes spent
Dec 15: £30 on shoes spent

Then an email would be sent out shortly after with the coupon code (or I could be informed and send the coupon manually?)

Thanks very much in advance,
Ben
