Since version 2.0.2, we added two modes for sending the due reminder email to customers.
Days after the first payment:
suppose a customer order a deposit product on 1 June, and the shop admin sets a reminder date to 7. now, the customer will receive an email notification after seven days, which means on 8 June.
Based on product status:
in this mode, the reminder email will send when the order status manually changes from "Deposit Payment" to "Selected Order status from reminder option."
This mode is beneficial for those shop owner who takes custom orders for products or delivers products globally.
Manual Deposit Reminder:
Like the default WooCommerce Order actions, now it's also possible to send reminders.
