Campagin on-hold subscriptions

We have a subscription business and with that comes churn and customers that put their subscription on hold. We would like to make a campaign for customers that have placed their subscription on hold and offer a discount on the first renewal if they activate their subscription. Do anyone have a suggestion on how to handle this without forcing the customer to start a new subscription? We have woocommerce coupons installed and are just starting with the Metorik tool.
