It's fine if the shipment is late, but it's not a good idea to send a notice of shipment when it hasn't been sent. The postmark will give away the date.
Sorry for the delay.
We confirmed the arrival of the product last night.
We apologize for the inconvenience.
The item arrived in beautiful condition, thank you!
I have received the product. The item was in good condition, but I cannot accept the fact that there was a major loss from the shipping notification to the actual shipping. That means it was reported falsely.
If there was a delay in shipping, would you have provided an explanation to that effect?
