Upsell block. Shows a product’s upsells next to the reminded item, then related products. Set a bigger pack as an upsell on the Linked Products tab.
Subscription nudge. When WooCommerce Subscriptions or All Products for Subscriptions is active, customers who bought the product often enough get a subscribe and save link to the product page. Other plugins can use the wfrrp_subscriptions_active and wfrrp_subscribe_url filters.
Marketing sync. Pushes the events reminder due, reorder clicked, reordered and reminders stopped to Mailchimp, Klaviyo or a webhook signed with HMAC SHA256 in the X-WFRR-Signature header. Let that tool send the emails is an option: the store then sends nothing, and the reminder due event carries the reorder and stop links for your own template. Mailchimp only accepts events for people already on the audience.
