Sending Webhooks would allow to integrate with any software outside of WordPress (through Zapier for example). (A Webhook Trigger would also be great). In this Action the admin would select which fields to send (username, email etc.), and of course where to send (URL), maybe the request method (GET/POST).

A trigger when a customer logs in. This would also need a "Customer Login Count" Rule

Github Issue: https://github.com/Prospress/automatewoo-subscriptions/issues/3

Trigger: coupon about to expire within X hours/days Would be great to trigger some last minute sales + this would make an awesome follow up.

It would be helpful to export a list of email addresses that have been sent a specific email and has been viewed/not viewed

This could also include sending SMS.

A workflow could be triggered from a webhook

It would be great if we could base workflows based on the last time user has logged in into their account. That is a good way to recognise inactive customers if the service requires login in order to be used. For example a restricted website for paying customers, an external app using WordPress login to allow access to the app, and more.

after Last login (time) - send email after Last purcharse (Time) - send email etc...
