WooCommerce, Reminder report shows reminders sent, click rate, reorder rate and revenue for any date range and category, split by email, product and category, with CSV export.
A reorder is an order for the same product within 30 days of a reminder, or through its link at any time. Revenue is the line total after discounts, without shipping and tax. Part refunds do not lower it, while fully refunded or cancelled orders are taken out. An optional weekly digest email for the store can be turned on under WooCommerce, Settings, Emails.
