Vanquish Shipping Tracking for WooCommerce

Yes. The free version links to the carriers' tracking pages and needs no external account or API key. In the premium version, the in-site timeline is the only feature that uses a tracking service — with your own API key.

Yes. The checkout features (requested delivery date, delivery estimates on shipping methods, per-product shipping estimates) work in both the block checkout and the classic (shortcode) checkout.

Yes, the plugin is fully compatible with HPOS and with the classic order storage.

No. Your orders keep their tracking: carrier, tracking number and dispatch date are converted the first time each order is loaded, so there is no bulk operation to run. Custom carriers, and the extra shipments and notes if you used them, come across too. Your settings are migrated as well: the tracking messages (including every language, on a WPML or Polylang site) and the order statuses the tracking is shown on. The placeholders are the same in both plugins, so your wording carries over unchanged. Anything that has no equivalent in the new plugin — most of the old options page was workarounds this plugin no longer needs — is simply left behind, and the advanced features have their own settings pages to fill in. The migration never overwrites something you have already configured here, and it does not delete the old plugin's data.

Yes. Every email is a standard WooCommerce email, so you edit it under WooCommerce → Settings → Emails, exactly like the ones WooCommerce sends itself: subject, heading, extra content, the enable switch and your store's branding. The plugin adds "Order shipped", "Shipment status update" and "Shipment needs attention" (the last one goes to you, not the customer, and lets you set the recipient). The tracking block inside those emails comes from the message you write in Shipping Tracking → Messages, where you can use placeholders such as the tracking number, the carrier name, the tracking link and the products carried by that shipment. On top of that, the two monitoring emails accept placeholders in their Subject, Email heading and Additional content fields: {order_number}, {tracking_number}, {carrier} and {associated_products}, plus {status} on the status update and {issue} on the admin alert. So a subject like Your {carrier} parcel: {status} or an extra line saying This parcel contains: {associated_products} works without touching any template.

The plugin ships translation-ready (POT file included). On top of that, if WPML or Polylang is active, the settings pages show one input per language for every customer-facing text (messages, labels, estimates), so you can translate them without extra tools.
