CrossSell Mailer – Post-Purchase Coupon Rules (Lite)

Description

CrossSell Mailer turns every WooCommerce order into the next sale. After a purchase, it creates a unique, personal coupon for the customer and sends it in a post-purchase follow-up email, with the product you want to promote. Then the results panel shows how many coupons were redeemed and how much revenue they brought.

Use it for:

  • Cross-selling: bought the T-shirt? 15% off the matching socks.
  • Repeat purchases: a thank-you discount for the next order.
  • Loyalty and seasonal promotions: Black Friday, Christmas, launches.

Everything runs inside your store, with your WooCommerce email template. No external email platform, no per-email fees, and your customers’ data stays with you.

How it works

  1. Create a rule: trigger product target product, discount, expiry and minimum spend.
  2. When an order with the trigger product is paid, the plugin creates a unique coupon locked to the customer’s email and sends it.
  3. The results panel counts coupons sent and redeemed, the redemption rate and the revenue of the orders that used them.

Does it work with any WooCommerce product type?

Yes. Simple, variable and subscription products are supported. Subscription renewal orders are skipped by default, so customers don’t get a coupon every billing period; you can enable them in Settings.

When is the coupon email sent?

When the order reaches the status you choose in the rule (Processing or Completed), once per order and rule.

Can another customer use a coupon that was not sent to them?

No. Codes are random and restricted to the billing email of the order that generated them. Developers can disable the email restriction with the ppcr_restrict_coupon_to_customer filter.

Can customers opt out?

Yes. Every coupon email includes a one-click unsubscribe link and a List-Unsubscribe header. You can also show an opt-out checkbox at checkout (classic checkout and Checkout block). Order emails are not affected. Only a hash of the address is stored.

How are results measured?

A coupon counts as redeemed when a paid order (Processing or Completed) uses it. The panel adds up the total of those orders and subtracts them if they are later cancelled or refunded. Counting starts with version 1.2.0.

Can I test the email without making a purchase?

Yes. Use the live preview and the “Send test email” button in the rule editor. No coupon is created.

Does this plugin change my existing WooCommerce emails?

No. It sends its own post-purchase email and leaves WooCommerce emails untouched.

Can I create more than one rule or send the email days later?

The free version has one rule and an optional global delay in minutes. CrossSell Mailer Pro adds unlimited rules, per-rule delays in days, categories and more.

1.2.0

  • New: live email preview while editing a rule (no need to save first).
  • New: coupon options — minimum spend, individual use only, exclude sale items.
  • New: GDPR tools — the plugin’s data appears in Tools > Export / Erase Personal Data, plus suggested privacy-policy text.
  • New: subscription renewal orders are skipped by default (no coupon every billing period); can be enabled.
  • Fixed: coupons were created without an expiry date (WooCommerce ignored it), so they never expired. They now expire at the end of the configured day.
  • New: results panel with coupons sent, coupons redeemed, redemption rate and revenue from redeemed orders.
  • New: optional opt-out checkbox at checkout, compatible with the classic checkout and the Checkout block.
  • New: “Send test email” button with sample data (no coupon is created).
  • New: optional daily cleanup of expired, unused coupons created by the plugin.
  • New: rules have a permanent id, so editing a rule never re-sends coupons for past orders.
  • Improved: all admin texts use WordPress translations (translate.wordpress.org ready), with Spanish, German, French and Italian included.
  • Improved: “Resend” now confirms the result and skips customers who unsubscribed.
  • Improved: the setup guide hides itself once the setup is complete.

1.1.3

  • Fixed: rules triggered on “Completed” sent two coupons and two emails per order.

  • New: one-click unsubscribe link and List-Unsubscribe header in coupon emails.
  • New: {{discount}}, {{coupon_expiry}} and {{unsubscribe_url}} variables.
  • New: order note with the generated coupon; coupon description links back to the order.
