WooCommerce Subscriptions provides a system to retry failed automatic payments: https://docs.woocommerce.com/document/subscriptions/failed-payment-retry/
This system includes customisable Rules to define what should happen at each stage of the retry process, like sending emails. However, it requires custom code to modify these emails.
It would be awesome to be able to use AutomateWoo's email (and other actions) based on retry events.
The most notable events are:
* when a retry rule is applied; and
* when a payment is retried.
There are hooks for each of these events that could be used for new Triggers, including:
To be most effective, there would probably also need to be some new Rules available to check on the number of retries, so different emails (and other actions) can be run at different stages throughout the retry process.
