FedEx (or UPS) sent me an e-mail with a tracking number and an expected delivery date. When my guitar failed to show up on that date I called them, only to be told they had no package matching that tracking number.
Both FedEx and UPS send notification emails as soon as we generate your shipping label. The initial notice states something like "billing information received" or "pickup information received". It's deceptive if you're not familiar with their system in that it quotes a delivery date and leaves the impression the package itself has been picked up. We generate a shipping label as soon as pack the guitar for delivery. That triggers the email with the tracking number. But until the carrier picks it up, scans it, and prepares the carton for shipping the message you receive on their tracking site is confusing. This can be even more aggravating if you live in the US. Occasionally a carton gets held at US customs before going on to the carrier.
Meanwhile you're chomping at the bit for your new guitar and getting upset every time a delivery truck passes your driveway. Being able to advise a customer of the location of their guitar by email is a great tool. You get a notice at every stage of the delivery cycle. But we wish the courier companies would re-word that initial e-mail to make it a whole lot clearer!
Keep checking their tracking site. Within a day or two the status will update so you know when to anticipate delivey.
