You can schedule requests for old Shopify orders fulfilled prior to Judge.me installation here.
You just need to give us the order creation date from which we will start (e.g. 6 months before Judge.me installation), and the maximum number of emails a buyer should receive from old orders (1 is recommended).
We need the maximum number of emails because we will process a lot of old orders at the same time, so if a buyer ordered many times we might send her a lot of review request emails at once.
We will skip the ones that are unfulfilled or already processed before, and apply your Review Request > Blacklist settings to the remaining ones. You will receive an email after we are done processing the old orders and the results of our work will be added to your Dashboard.
Note: this feature is only for Awesome plan.
