Hi @nathvi, we completed one final isolated live retest on October 1, 2026 (UTC). This was an actual signup through an administrator-only form, using only the site owner’s already-confirmed test address, not an editor preview or Send test email action. The automation was active and restricted to a hidden QA list.

The subscription trigger completed at 05:35:16 UTC, the delay completed at 05:36:50, and send-email completed at 05:38:52, with no step errors. The queue had exactly one recipient and one processed. The actual inbox received the welcome email at 05:38, still containing the literal XXXX-XXXXXX-XXXX. WooCommerce Coupons remains empty. Actual deliveries on September 26 and September 29 showed the same issue.

For this final run, the coupon block explicitly stored source=createNew, discountType=percent and amount=10, with expiryDay=30, usageLimit=1, usageLimitPerUser=1, individualUse=true and restrictToSubscriber=true. WooCommerce coupons are enabled.

Versions: MailPoet 5.39.0, WooCommerce 11.1.2, WordPress 7.1.2, PHP 8.2.34. Prior distribution checksum checks found no modified or missing plugin files. No other production plugins were deactivated and no customer orders were changed.

We have now stopped further troubleshooting, paused the automation and disabled both signup forms. Please retain this as a verified real-send placeholder case; it has not been resolved. Subscriber addresses, credentials and raw logs are intentionally omitted. Thank you.
