"This is with regard to last week's email in which you advised the factory of the sequence serial number, could you please forward this email to me? Please kindly include/copy me in on your email if it is relevant to shipping, inspection (i.e. shipping mark, schedule, golden sample, factory audit & cargo status etc). Thank you.
Please note that our customer is required to perform the evaluation for the mass production of PO xxx. Please kindly advise us of your mass production start date with respect to our arrangement. Please follow the sequence serial numbers from Elsa’s instruction."
This doesn't make much sense as in the first sentence you've asked for the email to be forwarded to you, but then in the second sentence you've stated that you only want the email on the condition that it is relevant to shipping/inspection/etc, etc.
Nonetheless, I've tried to make it clearer.
