Dear XXX,
I send the parcel by air mail today. Usually it‘ll take around the next 14– 20 days for the arrival. If there is a holiday, natural calamities or postal strike it may cause some delay. So please be patient and I sincerely hope that you’ll understand the cause.
After receiving the shipment, please let me know. If you have any question regarding the package, please feel free to notify me first and I will try my best to answer your question within the next 6 hours.
I’ll try my best to satisfy you with my products and I hope you can give me a five star feedback in return.
Welcome to my store, I feel much honored to have you as my client and thank you. Best wishes to your and your family!
Regards,
