...因為我担心會寄失物品,而且最緊要你能收到物品和得到你的好評呢!
...(It is) because I worry that the item may be lost in the mail. Furthermore it is most important for you to get the item and for me to get your positive feedback!
Whether the parcel/package that are delivered to you may be posted missing or not, you'll definitely receive your parcel/package,and let yourself a good comment to me.
It means sending and delivering parcel/package.
