If you want something more automated, look into the ShipStation integration for HikaShop. ShipStation can automatically send both branded shipment notices and delivery emails to your customers, automatically updates HikaShop order status and inserts the tracking code in the information area for the order, and quite a bit more.
Plus there's an awesome branded ShipStation tracking page for USA shipments. The page is partially customizable. For example, you can add your own business logo, change the primary color scheme, add some social media and contact info etc. It's not a fully custom page, but it's still worlds away from what most companies do, which is sending customers to generic UPS or FedEx tracking pages.
An example is online at the link below. This was for a real shipment I received a couple of weeks ago while visiting Miami.

It's a very powerful branding message for your eCommerce store. The page display updates as the shipped item is in transit. Try playing with it, like hovering over the location dots. If the customer wants to get the full scoop from the carrier, there's always still a link to the carrier tracking page too.
The HikaShop team worked with Polished Geek earlier this year to make several improvements to the ShipStation integration plugin for one of our client projects. It's a really nice system and our client loves it. It's an excellent way to improve your shipping related communication with your customers, integrated with your HikaShop store.
