I got a client who wants to have paid subscription and during the period of subscriptions, email will be sent to customer to do a health check form.
What form and autoresponder plugin should I use to create workflow like this?
1. Customers will pay 1, 3 or 5 years subscription
2. If subscription is active then autoresponder email to customers to fill health check form every three months, if not it will ask customers to pay subscription (goto #1)
3. If customer pay before subscription expires, the subscripiton will be extented
What should I use to create the process like this
Thank you very much in advance
